I see Dr Collier about once annually for a chronic aortic issue. He reviews results from an MRI always taken earlier that day, and answers any questions I have - until I run out of questions.

All care providers, Dr Collier, EKG tech and Echo tech were friendly and efficient. I felt I was in good hands

Reviewed on Jul 13, 2018

the doctor was 2 hours late!!!!!

Reviewed on Jun 8, 2018

The echocardiogram that I had scheduled should have been scheduled for a time earlier in the day so that I could have had that test done and then seen Dr. Collier at an earlier hour. As it was, I had an EKG test at 11, and then the echo wasn't until 2:30 which didn't begin until after 3:00. So I ended up waiting from 11-3 and then the echo took about an hour before I then saw Dr. Collier after 4. I didn't leave the clinic until after 5 o'clock. This was a long day for me. I am from over 1000 miles away from the clinic and so scheduling is important to me.

Reviewed on Jun 8, 2018

Dr. Collier's staff and nurse saw me early and without delay. It was the problem with the scheduling of the echo and the fact that the echo test didn't start until late.

Reviewed on Jun 8, 2018

I believe the echo test schedulers should have taken into consideration the fact that I needed the test done before seeing the doctor and have it scheduled at an earlier time or at least worked me in before 3 o'clock as I was there at 12.

Reviewed on Jun 8, 2018

I really appreciate Dr. Collier he took time with me and had a GREAT bed side manner. You get the feeling that your care is his concern and you are not just a number! I would recommend him to my family and friends.
