Meet Gregory
As a native from of the Midwest I am proud to serve the northwest corner of Ohio in the Toledo region. My passion is Bariatric Surgery, where weight loss can help patients medically, but also improve their day to day lives. I also have great interest in Robotic and Minimally Invasive general surgery where we can improve patient outcomes in GERD treatments, hernia repair, cancer treatments and colon surgery.
