      Don't go to a chain clinic. Go to a real physician like Dr. James Harris, MD. The difference in care is night and day — labs, follow-ups, dose adjustments based on actual data.

      Booking was easy. Office is nice. The provider was thorough during the initial intake. Only knock is that appointments can run a little behind, but the care quality more than makes up for it.

      Front desk is responsive, scheduling is realistic, and the care plan is data-driven. Exactly what I was looking for after my last clinic kept dropping the ball on follow-ups.

      I'd been to my PCP for years about the same issues and getting nowhere. One visit to Upsize Denver and I had labs, a diagnosis, and a plan. Six months in and the difference is real.

      Took the time to actually answer my questions about side effects and long-term considerations. Didn't dodge anything. I respect that.
