Positive experiences often highlight his ability to explain medical conditions thoroughly, his compassionate bedside manner, and his willingness to listen to patient concerns, even going the extra mile to ensure understanding.

I really like Dr O'Leary. Being seeing him for 3-4 years. Doesn't make me wait , asks questions about my current situation and answers all my questions concisely. I drive about 30 miles to see Dr O'Leary when I could travel to closer Duly locations for my cardiology appointments.

Love, love Dr. O'Leary.My Mom is 87 years old, very HOH.Dr. Speaks slowly/loudly, holds her hand in speaking to her. She has some confusion but includes her in conversation as she is able. Dr.O'Leary is a great MD as well!

He walked in the room and was very much in a hurry. It was a regular checkup, and everything looked fine from previous test that happened almost a year ago. He didn't ask if I had any questions or want to know about my life, which can be really important in terms of stress, exercise, etc. I felt rushed and tried to iterate so me things. It just seemed like I was at a fast food restaurant.
