Dr. Jason Sims, DO
Family Medicine · Board Certified
The same doctor. A better way to practice.
After years of caring for patients and families across Colorado — in Conifer, Golden, and beyond — Dr. Sims is opening a Direct Primary Care practice at KerixHealth in Lone Tree.
This new chapter gives him the opportunity to practice medicine with more time for what matters most: listening to his patients, understanding their individual concerns, and helping them achieve better overall health. With a smaller patient panel, you get longer appointments and real accessibility when you need him.
If you've been considering continuing your care with Dr. Sims, you can enroll now and reserve your place in his new practice.

What patients say about Dr. Sims
Excellent. I used to see Dr. Sims in Conifer and was very happy with his care. I recently reconnected with him at the Golden office and am once again totally pleased with the care I have received. He is very patient and takes the time necessary to provide a high level of care. I recommend him…
He always makes me feel like he is listening to my concerns and truly wants to find the right treatment.
