A bariatric surgeon and obesity specialist, Dr. Paya has performed more than 5,000 laparoscopic procedures since 2004 to help morbidly obese patients from all parts of the United States.Dr. Paya's dedication to the surgical treatment of obesity is reflected in his extensive education and continuing education certificates.

Dr. Paya went even further in his own education for related procedures, including LAP-BAND placement, Laparoscopic Roux-en-Y, Laparoscopic Sleeve Gastrectomy and revision surgery and regularly performs these procedures at his practice.Dr. Paya believes that weight loss surgery is a great solution for morbidly obese patients who have struggled to lose weight throughout life. In order to increase each patients chance of complete and permanent weight loss, Dr. Paya has developed a multi-disciplinary approach to augment and compliment every obesity surgery he performs. As a bariatric surgeon, he collaborates with a team of psychologists, nutritionists, anesthesiologists, exercise facilities and fitness trainers for a balanced approach with the goal of helping the patient achieve permanent weight loss. This proactive approach helps the patient address the challenges of permanent weight loss from every aspect, assisting in his or her rehabilitation to maximize healthy weight loss and maintain the loss once it has been achieved for the rest of the patients life. Dr. Paya and his staff believe that knowledge and education are key components in the success of each patients weight loss journey.Dr. Paya and the staff at SurgiThin understand that the patients decision to undergo bariatric surgery is not an easy one to make.
