"The wait time to see Dr. Katz is at least one hour in the waiting room, sometimes more. He runs lots of lab tests in his own lab to make his services ever more costly."
— RateMDs"Staff is tough to deal with and very unfriendly, billing is disorganized, and they do not have any sort of website or app that allows you to communicate..."
— Yelp"The best medical experience I've ever had. Everyone (front office, nurse, lab, radiology and doctor) was beyond friendly, knowledgeable and helpful."
