Waiting room was clean and neat. I only waited a few minutes before being taken to the exam room and I saw Dr. Colligan after a few more minutes. As usual he was friendly, professional and very thorough.

I only get one day a week to schedule a visit with Dr. Colligan in this office but it's still very convenient since I live out here.

May 22, 2021

I felt very rushed this visit. like the focus was in a hurry.

★★★★★

May 22, 2021

arrived 15 mins before my 10:15 m appt. other lady came in at 10:20, mentioned she had a 10:30 with my same doctor. at 10:34, the other lady was called before me. I questioned lady at front desk, who seemed new. she looked at the screen & quietly discussed it with the more tenured front desk lady. I was then simply told, "They'll call you back in few minutes." I wasnt called until 15 mins later. it was upsetting the lady didnt just apologize & admit she didnt check me in.

★★★★★

May 14, 2021

when I call, I frequently get sent to voice mail and returned calls are not timely. Also, the website has a link to Directions, but there are no directions to the office, only the office address. Would be helpful to state the office inside NC Baptist Hospital Atrium, use elevator, etc.

★★★★★

May 14, 2021

very friendly, helpful, and professional.

★★★★★

May 14, 2021

Filled out online update/registration, but had to stand in line waiting to check in for 12 minutes. Updated all my meds online a few days before the appt., but when I arrived no medication updates had been posted. went over all the same medication info with nurse while waiting for Dr. Colligan. Why ask patients to update meds online, and then ignore update only to go over the same thing in person?

★★★★★

May 14, 2021

I always am treated very well by Dr. Colligan's staff. Dr. Colligan is excellent and I trust his judgment when he suggests treatment plans and/or makes suggestions on what I should do.

★★★★★

I was contacted with a reminder of my appointment 2 days before, so after 6 months since my last visit, I was getting a little antsy.Also the afternoon before I got a voice mail asking me for any records my primary care doctor might have on me. I thought that was cutting it close. I returned the call with the information but the recording said my call would not be returned for another 24 hours. By then I would have seen the doctor anyway. Bad communication on their part, I thought.

★★★★★

May 1, 2021

The nurse assistant rushed me through an EKG rather curtly. I got the impression she was Leary of not having it on time before the doctor walked in.

★★★★★

May 1, 2021

This doctor has high praise on the Internet, so he must be good.

★★★★★

May 1, 2021

My daughter who went in with me timed the actual doctor's visit with him in the room. It was 4.43 minutes from Hello to Goodbye. It was neither good nor bad other than not being asked if I had any questions.

★★★★★

May 1, 2021

I appreciate Dr. Colligan's knowledge and is very thorough and helpful to me! He explains everything to me and helps me know and understand all of his concerns for me and my care!

I was sent a web site to sign in for my appointment. I used the web site and the last page showed I had an outstanding balance on my account. I had already paid this amount so I figured the payment was being processed.

During one of my recent visits I had to wait too long because the staff was down one person. As always, I had a tight schedule and after waiting and without me needing to urge or complain, April who was working the front desk (I apologize if I have that wrong because Vicki and others have been exceptional too) took me back and personally administered the EKG. I stayed on my schedule. Great experience. Thank you!

★★★★★

Mar 14, 2021

Dr Colligan is off the scale. I have personal examples I won't get into. I do recommend him frequently and my Mother in Law is now his patient. My wife is a retired CVICU Charge Nurse and would echo my comments.
