Dr. Marissa Tenenbaum, Plastic Surgeon


Dr. Tenenbaum is an Assistant Professor at the Washington University School of Medicine. She is board certified by the American Board of Plastic Surgery and was voted among the "Best Plastic Surgeons" and "Best Doctors in America" by St. Louis Magazine.

Dr. Tenenbaum graduated from Washington University, an institution she once attended as a medical student. By training several plastic surgery residents annually, she is involved with educating the next generation of plastic surgeons about cosmetic and reconstructive surgery.

At West County Plastic Surgeons of Washington University, Dr. Tenenbaum focuses on facial plastic and body surgery with a special interest in breast procedures including augmentation, breast lift, breast reduction and mastopexy-augmentation as well as breast reconstructive procedures. She honed her skills, including in-depth fellowship training in innovative cosmetic surgery procedures such as the Laser Bra, at Marina Plastic Surgery Associates in Los Angeles, California, under its director, Dr. Grant Stevens.

Born and raised in Minneapolis, MN, Dr. Tenenbaum started her training as a student and a triathlete at the University of Wisconsin-Madison.

She made the move to St. Louis to attend Washington University School of Medicine, one of the highest ranked medical schools in the country (consistent ranked in the top 10 by U.S. News and World Report). She graduated ninth in her class, earning the prestigious Alpha Omega Alpha (AOA), among numerous other honors.

Dr. Tenenbaum sought a career that made a real difference in patients’ lives. She’d seen an otoplasty (ear surgery) on a 6-year-old girl who had been teased in kindergarten, and knew that, for her, first grade would be different. With the encouragement of her mentor and chair, Susan Mackinnon, Dr. Tenenbaum decided to pursue plastic surgery. She was immediately attracted to the amount of skill and finesse that was required by surgeons executing delicate procedures, the variety of operations performed, and problem-solving nature that was required for success. After extensive research of training programs across the country, Dr. Tenenbaum came to the conclusion that she would benefit the most from the program right where she was, at Washington University.

After three years of general surgery at Washington University, Dr. Tenenbaum completed a year of research with Dr. Alex Kane, chief of Pediatric Plastic and Reconstructive Surgery at Washington University, in his craniofacial imaging lab, taking Dr. Tenenbaum to Copenhagen, Denmark, for work with collaborators. During her plastic surgery training, she won awards for the best clinical presentation two consecutive years.

“I believe that plastic surgery can be a life-altering event. Whether the culprit is an accident, cancer or simply aging, pregnancy or weight loss, plastic surgery can help patients feel “whole” again. In addition, our specialty demands that we are skilled and highly trained surgeons who put patient safety first, and I am also extremely proud of that.”
