I was born in raised in Trinidad and Tobago. I came to this country to work as a RN and then I decided that I wanted to learn more and pursued my dream of becoming a doctor. I attended the University of Central Florida for undergrad with a degree in micro and molecular biology and the attended the University of Central Florida College of Medicine. I always had a desire to help the underserved because of my experiences in both Trinidad and Tobago, as well as some of the hospitals I worked for in the U.S. In medical school, that desire also intersected with the desire to specialize in family medicine and global health. I applied to the Bristol Residency Program while I was doing an away rotation there. I am very happy to return for residency.

I love traveling, being with close friends and playing with my spoiled dog. I also enjoy reading novels, going to science fiction conventions, and crocheting - even though I am not very creative, but I can follow instructions.

I grew up in a small town in western North Carolina. After undergraduate studies in Durham, NC, I spent a few years working in medical and environmental research. I married my partner in crime and decided to quit studying and start doing! We saved up and moved to Tanzania for a year. There were many adventures, misadventures and a lot of amazing community health work. Inspired to do even more, I moved to Mexico for medical school and then to the American southwest for clinicals. I am thrilled to be back home in the Appalachian Mountains to start another chapter!

I am originally from a small town in Middle Tennessee. I attended college at Tennessee Tech University in Cookeville and received my degree in biology. I then headed to Blacksburg, Virginia and completed my medical education at Edward Via Virginia College of Osteopathic Medicine. I’ve always been interested in family medicine because it is so diverse, and each person has their own story. I think the best health care is delivered by building lifelong relationships with patients. I chose Bristol because of the excellent faculty and the close group of residents. I am very excited to continue my training in Bristol!

I am married to my college sweetheart, and I have three younger brothers. I enjoy running, playing chess, drums, and reading. My wife and I also love to play tennis, listen to music, travel, and attend concerts.

I was born in Johnson City and raised in Kingsport. I grew up always being outdoors - hiking, biking, and swimming, and I continue to enjoy these activities. I worked for a chiropractor for two years and saw the benefits of helping the body mechanically so knew I wanted to incorporate this type of medicine into my medical practice. This led me to attend Edward Via College of Osteopathic Medicine in Blacksburg, VA. 

My wife Yolanda and I are ready for our next adventure - raising identical twin girls! We both take part in mission work in the U.S. and internationally, and hope to always reach out to others in need. We have a tight-knit family mixed with Cubans and Americans and seems that we are always cooking and dancing around the house. 

We chose Bristol Family Medicine Residency because of the residents and faculty that I met during my interview. We wanted to come back home and work with people who enjoyed working together. Bristol was the best of both worlds!

I was born in Sacramento and raised in a rural town seated in the heart of gold country in northern California. I worked as an electrician for several years but was drawn into medicine after discovering my passion for helping and building relationships with people. My undergraduate years were spent in rural Nebraska as well as Kansas City, KS. LMU-DeBusk College of Osteopathic Medicine in Harrogate, TN provided my medical training and it was during this time that I met my incredible wife.

On my days off you will probably find me fishing, hiking, or playing some sort of game outdoors. I feel blessed and excited to be a part of the medical community in Bristol, and I can’t wait to see the awesome ways God will work in the community while I am here.

I was born in Miami, but mostly grew up in Salt Lake City. My parents are musicians, who taught me the importance of humanitarianism and passion in whatever I do. I am the first physician in my family because I wanted to use those strengths and contribute substantially to the world through medicine. I got my bachelors in exercise physiology at the University of Utah and a master’s in medical health sciences before attending Alabama College of Osteopathic Medicine for medical school.

I’ve been married to a beautiful, wonderful woman named Jessica for almost 7 years. Together, we raise two gorgeous and lively daughters, Milana and Avalyn. We enjoy rough-housing, watching movies, hiking and dancing to loud music together. I love snowboarding and sports. I play drums and piano and I also dabbled a bit as a professional DJ. I also speak Italian fluently.

I grew up in the mountains of Asheville, NC, and went all the way to Macalester College in St. Paul, MN for undergrad, where I double majored in biology and environmental studies. Then I came back south to attend medical school at LMU-DeBusk College of Osteopathic Medicine in Harrogate, TN, where I have been living with my wife Kat and our super energetic black lab, Haka.

I am very excited to be a part of the ETSU Bristol Residency Program. My colleagues and I have the opportunity to take part in building strong and important patient relationships based on trust and a mutual interest in their well-being. I think effective healthcare must be patient-centered, and based on equal respect for all patients.

In my free time, I like any sport and all kinds of things that get me outside in this beautiful area - soccer, basketball, disc golf, hiking, running and canoeing.

After moving around a few times as a kid, my family settled in a small town in Ohio, where I did most of my growing up. I attended Wright State University and have a degree in chemistry with a minor in French. Later, I studied at Ross University School of Medicine and completed most of my clinical clerkships in Chicago. I am interested in full-spectrum family medicine, and would love to work in a patient centered medical home in the future.

My husband and I love the Appalachian region, and when he matched at ETSU for his psychiatry residency, we were beyond excited. I am very thankful to complete my training at ETSU Bristol. The program has a good balance of family time with education, with a superb group of people and the opportunity to learn OMT!  

In my leisure time, I enjoy going on hikes through the beautiful mountains, gardening in the backyard, and spending quality time with my family and dog.

I am an East Tennessee native who is passionate about my Appalachian roots. I went to Centre College in Danville, KY for undergrad where I majored in Religion and played soccer. I returned to East Tennessee to attended ETSU Quillen COM for medical school and I am excited to continue my medical education close to home. At Quillen, I participated in the rural primary care track, which cultivated my interest in providing care in small communities. Ultimately, I would like to practice in rural East Tennessee with an emphasis on obstetrics and women’s health. I consider myself a sports enthusiast, both playing and watching. I enjoy cheering on my Tennessee Volunteers and the United States national soccer team, winning as many intramural championships as possible, and enjoying the mountains with all they have to offer.

I am from Richlands Virginia, a small coalmining town in Southwest Virginia. I attended King College in Bristol, TN for my undergrad education. During that time I began volunteering as an EMT, which significantly intensified my interest in medicine. I then attended Liberty University for medical school. During school, I developed a passion for Family Medicine and patient relationships. I enjoy seeing patients of all ages, women’s health, and office procedures. In my residency search, Bristol had the ultimate package. It was close to home, offered excellent training, and had the most amazing group people. After my residency training, I plan to practice rural family medicine, seeing patients in both the hospital and the clinic. My spare time is usually spent volunteering, fly fishing, hunting, cooking or spending time with my family. I am married to the love of my life and we are blessed with an amazing daughter.

I was born and raised in Richlands in the mountains of Southwest Virginia. I completed my undergraduate studies at the University of Virginia. Go Hoos! Though my plan was always to pursue medicine, I worked in and around the coal and mineral mining industries for a few years, while also working as a firefighter and EMT. I attended the Post-Baccalaureate program through the Edward Via College of Osteopathic Medicine (VCOM) in Blacksburg, VA and then stayed at VCOM for my medical education. During my clinical rotations, I was lucky enough to rotate through Bristol and knew where I wanted to train for residency! The awesome residents, amazing faculty, and their dedication to family medicine were an instant draw for me! In my free time, I enjoy hunting, fishing, boating, hiking, and NASCAR – after all, It’s Bristol, baby! After completing my training, I hope to stay in the region to practice.

I was born in Miami, Florida and grew up in South Florida for most of my life. I love any outdoor activity that allows me to include my chocolate Labrador.  I also enjoy archery and doing mechanical work on my car. During undergrad I studied Forensic Science with a minor in Criminology. I attended Ross University School of Medicine shortly after that.  I fell in love with family medicine during my third year of medical school.  I choose Bristol Family Medicine Residency after seeing the confidence each resident exudes from being well prepared by the well-structured program, and the availability of challenging cases.

My wife Angie is currently finishing up her Bachelors in Health Business Administration. We meet in High School while attending a bible study at my parents’ house.  It was a match made in heaven the day I met her.  My wife and I enjoy attending a variety of social activities- sports games, concerts, etc.

Greetings from the Northwest!  I was born and raised in Montana and completed medical school at the University of Washington.  Prior to medical school, I met a handsome man from southwest Virginia and we always planned to move back to the area to be close to family and the family farm.  We could not be happier to be joining the Family Medicine residency program at Bristol!  In our free time, we love being outside.  I am eager to learn to garden in a climate that offers more than 3 months of growing weather!  I grew up in a small town and hope to ultimately practice in a rural area where I can provide affordable care to my neighbors.  The ETSU Family Medicine program is perfectly matched to that goal and I know I will finish residency well trained with my humanity intact.

I grew up in a small town in Northeast Mississippi on the Mississippi and Alabama state line. A family friend, who was a nurse, introduced me to healthcare as a career. This led me to my first job in healthcare as a nursing assistant. I worked as a nursing assistant while attending college at the University of North Alabama to obtain my BSN in Nursing. I worked as a registered nurse for 17 years and found the job to be very rewarding, however I felt that I had a calling to practice medicine and decided to pursue that calling. I attended medical school at the Alabama College of Osteopathic Medicine and have spent the last two years of medical school in Northwest Alabama in my clinical rotations. I have always had a desire to practice family medicine in a rural setting and I feel very fortunate to be a part of the Bristol family.

My wife and I like to spend time outdoors, we also love to travel and attend concerts and sporting events. I personally enjoy creative hobbies such as woodworking, drawing and painting. I am also an avid outdoorsman and love hiking, outdoor photography, fishing and gardening.

I have special interests in geriatric medicine and patient education, especially diabetes management. When searching for a residency, I knew I wanted to train in an area that was close to my hometown and family. After completing a rotation in Bristol, I knew this program would be the perfect place to obtain an excellent education while working alongside truly wonderful people. It would also allow me to be close to my family! I am excited to start this new adventure in Bristol!

Since I was young, I have sought to live “a life less ordinary.” I grew up in Sevier County, in the shadow of the Smokies. After earning music degrees from Carson-Newman College and Western Carolina University, I enjoyed thirteen years of teaching and administration in independent schools in Wisconsin, South Carolina, and Georgia.

A wilderness first responder course showed me a new passion, and I soon began prerequisites for medical school at Agnes Scott College in Decatur, Georgia. I then joined the inaugural class of the Auburn campus of the Edward Via College of Osteopathic Medicine. Following my second year of medical school, I participated in ETSU’s Appalachian Preceptorship, which led me to discover Bristol’s family medicine residency. Bristol’s residents and faculty seem like a family to me.

In my leisure time, I enjoy reading, collecting socks, and adventuring with my wife, Dottie, and our dogs, Chewy and Mocha.

I was born and raised in the Portland, Oregon area and attended medical school there at Oregon Health Sciences University.  Most of my hobbies are things I can do outdoors with my family (camping, hiking, bicycling, and snowboarding) but I also ran my own automotive performance shop prior to medical school and love drag racing and other motorsports.  During my previous career I had several opportunities to travel to the south and loved my time there, so Bristol was high on my list of places I wanted to live during my residency training.  That combined with the great training offered by ETSU drew me to the program here and I’m excited to become part of this amazing community.

I grew up in Morristown, TN, where I dreamt of becoming a physician since I was 2 years old. As I grew older this dream persisted, so I earned my bachelor’s in biology from Austin Peay State University before attending Medical School at Ross University. Growing up in a rural area develop my passion for serving underserved populations and medical missions. During medical school, I volunteered at community clinics to provide preventative services and education on healthy lifestyle. I have also been able to participate in medical missions with Remote Area Medical and the U.S. Navy comfort mission in Dominica.

Outside of medicine, I am a Disney fan, and enjoy traveling. I have a goal to visit every country in the world, having already visited Greece, Russia, Australia, amongst others. I enjoy the outdoors including hiking and paddle boarding. We have several pets: a labradoodle, two birds, and two cats.

I grew up in a tiny mountain community nicknamed “The Valley Above the Clouds” in Suches,
Georgia. My roots are as Appalachian as they come and I’m proud of where I’m from. After
graduating from the smallest public school in GA - with a graduating class of 12, I might add - I

Therapist. I attended Mercer University School of Medicine in Georgia from 2015-2019. I have a
great deal of interest in Direct Primary Care and intend to one day open a practice using the
model. Outside of medicine I have innumerable hobbies and interests. I am a die-hard Star
Wars fan and ran a book club in medical school which led to the creation of one of the best Star
Wars sites on the web which I continue to run today - My wife and I also enjoy
car-camping in my 4Runner, #doglyfe with our poodle, Rey (yes named after the Star Wars
heroine), board games, craft beer, and all things nerdy.

I grew up on a family owned cattle farm in LaFayette, Georgia. I received my undergraduate
degree from Berry College in Rome, Georgia before receiving my medical education from

allowed me to develop an interest and passion for full spectrum family medicine, particularly in
the areas of women’s health and pediatrics.
Some of the things I enjoy are fishing, weight-lifting, and exploring local parks, as well as
working with my brother on farm projects.
I am excited to continue my training through ETSU in Bristol because I was impressed with the
residents that I met at the program and the strength of the training that the residents receive. I

I enjoy spending my spare time with significant other, Patrick, and our four cats.

I am a native of East Tennessee and grew up in Carter County, outside the small town of Elizabethton.  I attended ETSU for my undergraduate degree and Liberty University College of Osteopathic Medicine in Lynchburg, VA for my medical education, where I fell in love with OMM.  I am excited to be back in East TN for residency and to serve the community I’ve been blessed to call home.  I was drawn to Family Medicine because of the unique patient relationship that occurs in family medicine, and also for the ability to take care of people of all ages.  It was clear to me during my interview at Bristol that this residency program was the perfect fit for me; from the family atmosphere to the wonderful faculty and staff, the Bristol residency just felt like home.  During my days off you will probably find me riding horses, spending time with my family and spoiled rotten German Shepard, or watching football (Go Vols!).  We also love outdoor activities like camping, hiking, and chasing waterfalls. Fun fact: I actually having camping to thank for meeting my husband!
