I was referred to Dr. Donnellan by my cardiologist, Dr. Cheeran, and I couldn’t have been more pleased with my experience. From the moment I arrived, the entire staff was warm, welcoming, and professional. I was especially impressed that there was virtually no wait time.
The doctor took an incredible amount of time with me and never made me feel rushed. He carefully explained my EKG and answered every question in a way that was easy to understand. His patience, kindness, and excellent bedside manner immediately put me at ease and gave me great confidence in his care.
It’s rare to find a physician who is not only highly knowledgeable but also genuinely takes the time to listen and make a patient feel valued. I am so grateful for Dr. Cheeran’s recommendation and would highly recommend Dr Donnellan too anyone needing an electrophysiologist.
