Christal Crooks, M.D.
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 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.
Reid Usedom, D.O.
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 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.

Wars sites on the web which I continue to run today - youtini.com. My wife and I also enjoy
