Dr. Mackler has followed my care for 5 years and as our meetings started to happen less and less, he still maintained rapport with me as if he had seen me a week ago. He gave great advice, spoke to me on my level, and remained professional at all times.

Dr Mackler is a caring and attentive Dr. We have seen him for quite a few years and have been impressed with how well his office runs and the wonderful people that work there. He always takes the time to go over the test results and answer any questions we have.

Dr is very easy to talk to. Went over all the test results explaining as we went. Did a physical exam and reassured us that he is doing everything he needs to do, is engaged socially at senior center and shoots pool with friends. Will see Dr. next year after we do the blood work. We really are pleased with the doctor and the whole office.
