I would highly recommend Dr Chapman to anyone who has stomach issues, after going to a local GI and he did many test on me and couldn’t find the problem, he referred me to Dr Chapman and after reviewing my records he asked if anyone ever checked for Celiac, I said no so we did bloodwork and it was borderline, and I started to feel better. Well after last year and all it’s craziness it started again and I just went back we did bloodwork again and now he said I Have Celiac Disease. Now I’m following a gluten free/dairy free diet and I hope to see changes. He is a great doctor! After following the diet since February I’m still have problems so he is checking other things out, said he won’t stop until we solve the problem! I really like this in a doctor!

My experience at the offices of Dr Casey Chapman could only be described as a cathartic out of body experience. I was greeted by a staff that had the resemblance of the Gods of Olympus. Making one question their own place in the world wondering why one would deserve such an angelic treatment. As far as the treatment of patients goes, the gentle and caring approach of the staff emits a sense of comfortability only rivaled by the comfort of your own mother. You will leave this office with a sense of clarity of your condition, confidence in your outlook, and security in your health. I cannot recommend this palace of healing enough as they have assisted me in becoming the best man I can be. Ps… The staff really is genuinely gorgeous.

Dr. Chapman and his staff handle their patients with the utmost respect and empathy. The support and resources are exceptional. I came here with a very complex set of issues after years of Crohn's disease and messy gut scarring from endometriosis + laparoscopic surgeries. He was able to navigate the details of my symptoms, history, lifestyle, etc. and help me vastly improve my problems and my overall quality of life.
