July 18, 2025Zachary W.Verified patient
I did not care for the environment at all and would never . All the questions asked were not relevant. The reason I was there and the reason was not actually discussed. He did tell me that if I’d like to leave they won’t charge me so I left.

This was my first primary care appointment since moving out to CO and I was a little nervous- but everyone was so kind and doc was great!! Very intelligent and helpful.

Dr. Knols is a clear communicator with a calm and approachable demeanor. Helpful staff. Clean office. I needed a refill on a prescription andI was in and out quickly.
May 15, 2025Natasha H.Verified patient
Was in and out in under an hour. The dr was friendly, answered the few questions I had and talked me into a referral for a mammogram even though I've been avoiding doing it. It took me a couple trips around the parking lot to verify I was in the right place, but the office itself is really nice and so was the front desk staff.

Friendly, communicative and engaged. Dr. Knol asked questions and provided feedback on a first visit that demonstrated he was informed and took the time to review my health history.

I had my first appointment with Dr. Knol this morning. He was friendly, personally and had a comforting bedside manner (which I really appreciate!)!
The office staff and Phlebotomist were equally friendly.
I'm grateful.

amazing comfortable experience.
May 3, 2024Herman B.Verified patient
Dr was friendly and seemed to listen but when I reviewed my after visit notes on mychart it read like he wasn't listening or that the notes were for a different patient and frankly that makes me lose confidence in this provider. After the followup for my medications I will be switching providers.

I was told i didn’t fill out their paperwork which I never received. He owes me a prescription of 6 bottles of Levemir today to South City Market. Durango Colorado. We are reporting this to the med board across the region
June 29, 2023Christa T.Verified patientVideo visit
Dr. Knol seemed pretty durect, a clear communicator, and a bit in a rush. Nothing like my primary I had back home. But it was a last minute appointment and he was able to refill my medication. I’m happy with him so far.

The staff and Dr. Knoll were all very friendly, knowledgeable and helpful. I had a great visit and Dr. Knoll’s demeanor has really put me at ease so I highly recommend this clinic
June 1, 2023Doreen V.Verified patient
Dr. Knol was extremely friendly, and best of all he is a doc who LISTENS to whatever you have to say. He asks about any concerns you have and is ready to actually discuss them. He is not like some rushed doctors who only give you a minute or two and then disappear without even listening to you. Dr. Joshua Knol is a very good, friendly, knowledgeable doctor who is easy to discuss matters with, and I am very happy to have him as my new primary care physician.
May 18, 2023Forrest S.Verified patient

April 18, 2023Greg R.Verified patient
Pretty happy with my experience. I haven't been to a doctor in 10 years - they made it a pretty painless experience for a newbie. Even though I didn't have my insurance card, they were understanding and had a plan to grab the information, which I appreciated. I plan to return!
More than 1 year agoZachary T.Verified patient
staff was really nice and Dr. Knol was great I'm always weary of changing to a new doctor but they all made it seamless and I am very comfortable having this Dr and office for my new medical needs.
