Jenna Beh joined Bay Bariatrics in November 2018 as both physician assistant and bariatric treatment coordinator. Prior to becoming a Physician Assistant (PA), Jenna was a registered dietitian in her hometown of Pittsburgh, where some of the first laparoscopic weight loss procedures were performed.

“Obesity is a deeply personal disease. I’m honored when patients choose to share their stories, struggles, and successes with me.”

When Jenna and her dog aren’t spending a rainy day binge-watching a new show on Netflix, you may bump into them walking on the beach, jogging around town, hiking through the woods, or practicing yoga.

*Dr. Tersigni did my operation, and I am so grateful that my postop has been almost completely uneventful and pain-free. I’ve lost more than 100 pounds from my high weight, and my diabetes, which I had for 10 years, appears to be cured. The good doctor and his staff have been so caring, and words cannot express my gratitude.
