The reviews listed below were collected independently of Collin County Pulmonary Associates through rater8. Each review represents an authentic and verified patient experience.
Everyone was very friendly. Didn’t have to wait at all. Just a very pleasant atmosphere and experience. Only took an hour for testing and diagnosis. I felt so much better about my COPD when I left. Dr. Chappell really encouraged me to exercise so that I’ll not only lose weight but greatly improve my breathing.

I really like Dr. Chsppell’s style. I immediately felt like he wanted to know a bit about me before testing and deciding on a course of action. I will recommend him highly.
