Dr. Peterson is really, really good. He has done two implants on my right upper and last week did one implant on upper left. He did a sinus lift during the procedure also. The last surgery, went so well all I needed was a little Ibuprofen; the stiches held as they should. I've had over 6 oral surgeries and the last one was the least painful. I attribute this to his skill, with the knife and how he stiches the wound. Can't really say enough!
