Vanderbilt is a excellent residency that will only get better over the next several years. The senior residents have all been able to accomplish their professional goals (3 private practice, 2 academic practice, 1 fellowship). You get to train with some of the more approachable and better known OB/GYN's in the country who have edited and written the major texts in the specialty. Dr. Gabbe (Gabbe's obstetrics) helps you learn diabetes in diabetic clinic, Dr. Jones (Telinde's gynecology) teaches in gyn oncology, Dr. Zimmerman (chapters in Telindes and past president of Society of Pelvic and Recontructive Surgery) teaches vaginal surgery. These are just of the few people who you will work with in a new financially stable hospital.
There aren't any fellows at Vanderbilt which means you are the first assist for radical hysterectomies, complex pelvic cases, and high risk OB cases.
The new chair is Dr. Nancy Chescheir from UNC and she has been universally lauded for her positive impact on the program.
Vanderbilt should be on everyone's list of places to interview if possible. The hospital is up to date and new, Nashville is a great city, and the opportunity to be a balanced OB/GYN with options for private practice or fellowship are there. Good luck.
