Undergraduate: University of Missouri 
Medical School: Texas Tech Health Sciences Center 
Why I Chose OB/GYN: I really love the variety that OBGYN has to offer. You can be in the OR, clinic and labor and delivery all in the same day. I truly enjoy all the subspecialties, which I believe is really important since I want to be a generalist. 
Why I Chose Chattanooga: I did a 4th year away rotation here and fell in love with this program. The people, including residents and faculty, were all so kind and welcoming. I also believe that the wide exposure to diagnoses and the acuity seen here will help prepare me for after residency. 
OB/GYN Areas of Interest: Generalist 
Hobbies: spending time with my family and dogs, hiking, water sports/swimming, reading, traveling

Hometown: Johnson City, TN
Undergraduate: East Tennessee State University
Medical School: ETSU Quillen College of Medicine
Why I Chose OB/GYN: OBGYN is the perfect combination of clinical contiuity with patients, office based procedures, and surgical procedures. I want to walk with my patients through every step of their life, from menarche to menopause and everything in between. I am also very passionate about women's health and advocacy and am proud to empower women to make choices about their reproductive health.
Why I Chose Chattanooga: I had the opportunity to do an away rotation here as a fourth year medical student and loved the culture of the program. We get great exposure to all facets of the specialty and surgical exposure early on. I truly think that this program will train me to be a competent, confident OBGYN upon graduation.
OB/GYN Areas of Interest: Adolescent reproductive education, underserved communities, reproductive advocacy
Hobbies: Hiking/ exploring the outdoors with my husband and two dogs, travelling, trying new restaurants, baking (macarons are my favorite thing to make).

Medical School: Pacific Northwest University of Health Sciences
Why I Chose OB/GYN: I did not know I wanted to do OB/GYN when I started medical school, but after my OB/GYN rotation, I knew I had found my perfect fit. Finding a specialty that allowed for surgery in the mornings, clinic in the afternoon, all while delivering babies in between is so exciting. And having the opportunity to take care of women across their lifespan while being and educator and advocate made it that much more appealing to me.
Why I Chose Chattanooga: I did an away rotation here and was excited by everything Chattanooga had to offer. There is such a diverse patient population with high-acuity needs, I knew I would receive great training. Not to mention I would be joining some pretty great co-residents!
OB/GYN Areas of Interest: So far generalist, but I love the obstetrical niche so we will see!
Hobbies: Hiking, fishing, brunching, binge watching Netflix.

Rachel Nelson, MD PhD
University of Tennessee Health Science Center College of Medicine


Hometown: Saratoga Springs, New York
Undergraduate: Siena College
Graduate: Wadsworth Center New York State Department of Health, University at Albany
Medical School: University of Tennessee Health Science Center
Why I Chose OB/GYN: OB/GYN is a unique field with so many opportunities to empower and care for our patients as primary care providers, surgeons, and subspecialists. I love that our connection with our patients and our community does not stop at the hospital doors. As OB/GYNs, we have the ability to create longstanding relationships with our patients, and to be allies and advocates for them through their reproductive care.
Why I Chose Chattanooga: I completed a rotation here during my fourth year at UTHSC. I was excited to find that the curriculum and teaching style perfectly matches my career goals and learning style, with a strong emphasis on surgical skill and evidence-based medicine. I also love that this is a smaller academic program - we have all of the benefits of a major teaching hospital (Level I Trauma Center, Level IV NICU, diverse subspecialty training) but with a close-knit, supportive environment and many opportunities for one-on-one mentoring. I feel very confident in knowing that I will grow into a skilled surgeon and clinician, as well as a compassionate advocate for my patients.
OB/GYN Areas of Interest: Reproductive Endocrinology and Infertility, genetics, LGBTQ health, reproductive justice, rural medicine.
Hobbies: Yoga, scuba diving, animal rescue and rehabilitation.
