Dr Costa runs a small office attached to his home. He has the abillity to see you when your able to come in. I have never had to wait more then 5 mins to bee seen. I never over charged me, made a treatment plan and stuck to it......no unnessary visits. I never felt that he prolonged the treatment to get money. I was feeling good and he pretty much "kicked" me out, said treatment was done and couldnt see charging me anymore money. I havent seen him in about a year, have to go back and get adjusted. You work directly with Dr Costa. ( he also runs the office) Overall, Great Doctor, loves to talk and takes time to explan everything.
