About Dr. Marvin
Dr. Marvin



Doctor Robert Marvin is a Board Certified Surgeon who specializes in Minimally-Invasive Surgery (Laparoscopic Surgery) for the cure of Morbid Obesity. He has additional Certification in Surgical Critical Care and has been recognized by the American Society of Bariatric Surgeons (ASBS) as a surgeon practicing at a Center of Excellence in Obesity Surgery.

Dr. Marvin is affiliated with Nobilis Health. He utilizes Southwest Freeway Surgery Center when a surgical procedure is required. Southwest Freeway Surgery Center is an outpatient ambulatory surgery center, offering patients a quality of care comparable to a concierge and a convenient alternative to a hospital-based care.  

Dr Marvin grew up in Orange County and attended the University of Southern California where he studied in the Honors program known as the Thematic Option. He was elected to Phi Beta Kappa and graduated Magna Cum Laude with a Bachelor’s degree in Biology in 1985. He then spent the next four years in Montreal, Quebec, Canada at McGill University at medical school, and subsequently graduated with the degree of MDCM in 1989.

Dr Marvin began his Residency Training in San Antonio at the University of Texas Health Science Center in 1989. He was chosen as the Administrative Chief Resident for the General Surgery in his final year, and was designated the Outstanding Laparo-endoscopic Resident Surgeon in 1994.

In 1995 he moved to Houston, Texas where he did additional training as a Fellow in Surgical Critical Care at the University of Texas Houston. The following year he was asked to join the Faculty as an Assistant Professor of Surgery and taught at Hermann Hospital with the Trauma Service. He practiced general surgery, critical care and trauma surgery until 2000. During that time he conducted clinical research and his work was published in multiple medical journals such as the American Journal of Surgery and the Journal of Trauma. He also was the main author on the chapter on Critical Care in Sabiston’s Textbook of Surgery that year.

In September 2000 he left his professorship to enter a Private Surgical Practice. Dr. Marvin has done additional training to learn the techniques of Laparoscopic Gastric Bypass (1992), the Laparoscopic Adjustable Gastric Band (2004) and the Laparoscopic Gastric Sleeve (2007) operations. Since the inception of his Obesity Surgery practice in 2002 he has performed surgery for more than 1000 patients suffering from Morbid Obesity with excellent outcomes and low complication rates. Because of the quality of this care he was recognized as a Surgeon practicing at a Center of Excellence by the ASBS in 2006. He is the Medical Director for Obesity Surgery for both Obesity Surgery Specialists and Houston Surgical Specialists in Houston. He is currently the primary surgeon for the Houston Obesity and Metabolic Disease Clinic.
