Dr.Haghighat is simply the BEST at what he does. I am in the military and started looking for a doctor to correct my gum recession on the lower canine. I found Dr. Haghighat from the recommendation of a friend who previously had work done by Dr.Haghighat and praised his high quality of work, I decided to contact Portland Implant Center. I have to say that Dr.Haghighat did exceptional work. He and his staff were upbeat, friendly and professional. I highly recommend him.
