"Dr. J, deserves six stars minimum. He has been our family Dr. for 35 years. He’s not in this practice for the money. He is one of the last physicians that’s in it to make a difference."

— WebMD Patient Review

"Worst care ever! Doctors don’t give you a complete physical, Staff doesn’t care about you. Paperwork is left on someone desk and never faxed... Save yourself time and frustration don’t go here."
