I feel SO fortunate to have Dr. Dever AND his staff on my health care team. One can just " feel" the genuine concerns and kindness from the staff. I can't express how happy and grateful I am. I finally found a health care team that will be able to help me!!

Best experience with a GI doctor I've had. I changed GI doctors and I'm so glad I did. Dr. Dever is caring and wants to help get me feeling better instead of saying "there's nothing we can do, it's part of your condition". Dr. Dever has brought back hope in my world. Thank you!
