Dr Chappell is a superior pulmonologist, He quickly reviews my case and then expanded our visit to explain how my high blood pressure issues related to my sleep apnea. He reassured me about my upcoming angioplasty for my lower anterior descending artery and also checked my carotid artery for sufficient blood flow. He’s empathetic and ensures his patients leave with a good understanding of their future needs to keep their condition stable. Highly recommend Dr Chappell
