Early morning medical procedures are rarely something anyone looks forward to especially when they require an unpleasant 24 hours of preparation. But the staff here clearly understand that. From the moment you walk in, you're greeted with a level of warmth and compassion that immediately puts you at ease. Someone has taken the time to train this team to recognize what patients have just been through, and it shows. You feel welcomed, not processed. The facility itself is spotless and well run, adding another layer of confidence before the procedure. And then there’s Dr. Michael Mills. In an era when medical histories sometimes feel skimmed over, Dr. Mills is in a class of his own. He reviews your history as if he were preparing to defend a thesis on it during your appointment. That level of preparation and attention is rare and deeply reassuring. Dr. Mills is a winner. And the staff? An unexpected bonus.

Beat the Trend of Early-onset Colon Cancer through Timely Screening
Colorectal cancer cases rising in young adults is a concerning global trend. The best way to beat the trend is to prevent or detect the disease early through timely screenings.
My health status had changed pretty quickly, and I’m grateful that Dr. Mills was able to see me quickly for a consultation, and then schedule my upper and lower endoscopy fairly soon. I found the staff at the endoscopy center to be highly professional and very well organized. My procedure went flawlessly. It was delayed a bit because of a complex case, which was no problem for me. It was overall a highly satisfactory experience.
