First and foremost welcome to Mason. I moved to Mason from Raleigh, NC about 4 yrs ago. Moving from the South to the Midwest can be quite the adjustment....especially if you are originally from the south. So if you ever have questions or need to talk, let me know. I can give you pointers on differences I have learned over the past 4 yrs between NC and here. :-)
So for Doctors.....I take my kids to GHA-Mason on Mason Montgomery Road. I really like it there. Some of the highlights are that they have Sat morning office hours and they have a pharmacy right on site that is very conveneient. My kids go to Dr Robinson and he is great. But there are several other peds there that are good too including Dr Kryvski (sp?). I also go to this office myself as they have Family Patrice docs as well. I am very rarely at the Dr so dont know if I could recommend one per se, but I usually see Dr Jay Hayner.
Now my OB ...... I absolutely LOVE. The office I go to is on Montgomery Rd called NE Center for Women's Health. The office is really busy which can be a pain but I love my Dr there. I go to Dr Sullivan. He is fantastic, makes me feel very comfortable and I can ask him anything. Actually I go to him for more stuff than my regular Dr.
For vision and dentist I dont really have any good recos.
Well good luck and let me know if you have more questions. I also have an 8 yr old son and 2 yr old daughter. Welcome to Mason.
