I just went to Dr Colligan about a little over a month ago This has been the worst experience I have ever had with any physician in my entire life. I cannot get timely information regarding test and monitor results. I also cannot get his office to provide me with cost information. I cannot get his office to call me back. I cannot get their office to answer their phone (put on hold for very long lengths of time). Absolutely horrible. I would be very dissatisfied if this were about my pet.

Dr. Colligan and the staff in the office were great!!! I was taken in on time and Dr. Colligan spent a lot of time with me explaining what was going on, next steps and what to expect in the future. He even followed up with me on the weekend.

I've been going to Dr Colligan for about a year. His staff is friendly and efficient. You see the Dr within 10 minutes of arrival. Dr Collidan is open, informative, positive and to the point. There is room for discussion, questions and your input, and he is clear / direct with his thoughts. Overall, a perfect balance. I believe he knows his stuff and that he has my best interest in mind.

Dr. Colligan has been my cardiologist for over 5 years..He has shepherded me with great care through the entire gamut of diagnoses, prognoses, open heart surgery and continuing follow-up. His professional experience and competence combined with his personable "bedside manner" makes him an exceptional doctor. Notably, I have referred both friends and family and they have all been very happy with Dr. Colligan We all have the highest regard and confidence in him. .

What a wonderful experience ! Scheduling was easy. The staff was amazing. My appointment was at 8:40 and I was in the room being checked in at that exact time. I really liked his nursing assistant. Dr Colligan was so nice. Took a good history and let me know about follow up.
