John R Roost, DO

Obstetrics and Gynecology

Accepting New Patients

Meet John

Since moving from Michigan to join Mercy Health Physicians and gaining my board certification in OB-GYN, I have developed a strong connection to the Perrysburg area. It has been exciting to see the growth here including the new Mercy Perrysburg Hospital and to continue to make connections to patients and families in this area. I have a special interest in patient centered obstetrics, including high risk, along with gynecological Robotic surgery.
