Dr. Ahearn has been my doctor for over 6 years and has taken very good care of me. I feel like it's due to him that I have been stable for 6 years. He is very caring and personable and takes as much time as it takes for an office visit. I never feel rushed. I highly recommend him.

After being misdiagnosed by another doctor with a chest xray Dr Ahearn was able to read my xray properly and helped immensely answering questions and addressing my concerns and most importantly got me feeling better!! What a great change from previous doctors who just wanted to get me in and out! A very caring doctor who takes the time!
