He treated with respect and didn’t talk down to me. I could tell he really cared and was focused on finding out and helping me with my situation. He made sure to ask me if I understood everything he said and took the time to listen.

Dr. Mackler is aways completely prepared for the visit. He always reviews test results prior to the visit and is prepared to discuss results, the meaning of the results, and ready to answer questions without rushing through the visit. He is very professional yet very friendly.

I have been a patient of Dr Mackler for many years. As for me he has been tne best. I'm sure he would rather a CURE be found for Cancer than to have to tell one more person they have Cancer. Am sure he would rather dig ditches than to get up one more day to tell someone they have Stage IV Cancer as he had to tell me. I could not do his job every day.
