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!

From the moment I walked through the door, I was met with warmth, professionalism, and genuine care. Dr. Dever is truly outstanding—not only highly knowledgeable and skilled, but also compassionate, patient, and attentive. They took the time to listen to my concerns, explain every step of the process clearly, and made me feel completely at ease.
The staff deserves equal praise. Every team member I interacted with was friendly, efficient, and kind. They handled everything—from scheduling to follow-up—with incredible attention to detail and a smile. You can tell they genuinely care about their patients.
This practice sets the gold standard for medical care. I highly recommend Dr. Dever and their wonderful team to anyone looking for top-notch, personalized healthcare.
