A.D.
One of my good friends lived there and said this for you:
We lived in Marietta (West Cobb and they have great public schools, and some great neighborhoods at a decent price point. East Cobb (also in Marietta) is nice. Another great area (but taxes a little higher) is Alpharetta and surrounding areas. I am sure the real estate agent could make other recommendations, but I would definitely include those in my search.
