Dr. Randal Baker and Dr. Derek Nagle are amongst the most experienced bariatric surgeons in Michigan. Grand Health Partners physicians have performed over 10,000 surgeries! Our providers are known for their innovation and dedication to bariatric patients. It is that dedication that has enabled Dr. Baker and Dr. Nagle to continue to care for bariatric surgery patients who live in the northern Michigan area.

Grand Health Partners is proud to announce that we will be expanding our brand to reach areas of Northern Michigan who may not have previously had access to these weight loss services. We have established a satellite location where our physicians, Dr. Baker and Dr. Nagle, and other bariatric providers can see patients in Petoskey. These providers have been servicing the Petoskey area under McLaren Northern Michigan for over 6 years and have experienced great patient success.

Obesity is the second preventable cause of death next to smoking. It is a disease that effects more than one-third of US adults according to the Journal of American Medicine. Here at GHP, we believe that no geographical area should be left out of having bariatric medical professionals available.
