Bariatric Surgery Staff

Take a few minutes to get to know and learn more about our caring bariatric surgery staff members as you begin your weight loss journey.

Dr. Fitzer

Dr. Fitzer is an ASMBS Bariatric Center of Excellence surgeon, and he’s our center’s director. He is Board certified, fellowship-trained, and a fellow of the American College of Surgeons. He decided on bariatric surgery during residency, where he realized that there is no other act in medical practice that does as much good for a patient as does a well-performed weight-loss operation.

Dr. Fitzer on his enthusiasm for bariatric surgery: “There once was no way to cure type 2 diabetes. As a bariatric surgeon, you do that all the time -- some days twice before lunch.”

Danielle Fitzer, RN, BSN, CBN

Danielle Fitzer, RN, BSN, CBN. Danielle is our lead patient care navigator and all-around patient advocate. Bariatrics has been her focus since graduating nursing school, and she is a Certified Bariatric Nurse. She supervises the process of securing insurance approval for our patients. She is very knowledgeable, and she probably knows the answer to just about any bariatric-surgery-related question you can produce.

Her outside interests include fitness, travel, and family.

Jessica Marmo, RD

Jessica Marmo, RD. She's yet another one from Pennsylvania. She grew up there, graduated from Penn State, and enjoys traveling, hiking, and doing various outdoor stuff with her dog (Moose). On picture day, she opted for something that was not black and sleeveless, providing needed evdence (to Dr. Fitzer's relief) that such is not our uniform.
