L.H.
Dayton OB/GYN has several Doctors. I recommend Dr. Michael Theising and my 2nd choice is Dr. Brent Imbody. They have lady Drs as well if you prefer. I have been with the practice for 11 years now (Dr. T to be exact) and they have delivered 3 out of 4 of my kids. I have recommended them to my friends and family and have had no complaints thus far.
937/208-6800 - for their Downtown Dayton office. They also have 3 other offices: Centerville, Beavercreek and Fairborn.
