Joann Garcia Post-Operative Coordinator  “Helping patients after surgery allows me to hear about their latest triumphs, like being off of medications, running with their kids, getting promotions at work. They’re so happy, it makes me feel good to be part of Dr. Yadegar’s team.”

Mary Clark Community Education “It’s important to let people know we’re here and what Dr. Yadegar has to offer. I’ve been working in this field for more than 10 years, and Dr. Yadegar is an expertly skilled surgeon, nurturing caregiver, and excellent teacher. That’s why he performed my weight loss surgery!”
