K.H.
Well, they aren't in Grand Blanc, but Flint so I guess that's close enough...
Dr. Nita Kulkarni - She is mine and just delivered my first baby. I love her so much! She always makes sure you don't have any more questions or concerns before leaving you. The only pitfall I can see (and I don't think it is, but some people might) is that she's the only OB/GYN in the office and it's a small office so they don't have a whole lot of big equipment. Alot of the testing and such is done at the hospitals. A good point is that she can go with any of the area hospitals - she's not contracted under just one like alot of doctors are.
Dr. Mona Hardas - She's great. I've met her and have heard wonderful things about her. My mom works at the Hurley labs and a lot of the ladies in the hospital use her and like her very much.
Good luck! I know it sucks trying to find new doctors. My OB/GYN retired 3-4 years ago and I had to search for a new one. Having a mom that works at the hospital with alot of other ladies did help that search a lot though.
