"We have a special needs daughter who needed her foot looked at. Thankful that Affinity accepted her Medicaid first of all. Staff was nice, did not have a long wait, doctor was knowledgeable and understanding with our daughter, which means a lot. She was able to get x-rays done on her foot and received the results before we left. A great place to go on short notice."
