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.

	March 2022 They are all very thoughtful and care about you and your situation!!!
	January 2022 Great care
	December 2021 Mercy has always been the best!
	December 2021 Very happy with Dr. Johnson. He is an excellent caring doctor. The staff is great as well.
	November 2021 Dr Johnston was fabulous, he didn't make me feel like just a number he was attentive and very personable
	November 2021 Dr Johnston is by far the best doctor I've ever come across. His bedside manner is more than anyone can desire. He shows compassion and answers all of the questions you may have.
	September 2021 Dr Johnston has the best bedside manner of any physician I've ever seen! He is very concerned for the health and well being of his patients.
	August 2021 I saw Dr. Johnston for a post-op visit. This surgeon has saved my life, quite literally, three times. He's absolutely amazing. He's extremely professional but every once in awhile I'm able to get a little smile or chuckle. I wouldn't trust anyone else with an abdominal surgery.
