Dr. Renke was very impatient, not friendly at all, and, in my opinion, very unprofessional. He answered my questions very rudely and impolite. He also charged me $75.00 for seeing me for two minutes, where he didn't even do anything but look at my teeth for a second and glance at X-rays that ANOTHER dentist had taken. Dr. Renke was so rude that I will surely take my business elsewhere - even if that means I have to pay double somewhere else.
