Dr. Johnson professional and focused care for me with my left knee replacement and follow up care gave me confidence that I received the best care.
- 5 out of 5 starsReviewed on 1/8/2026
I like Dr. Johnson very much. This practice and I are still fairly new to each other, so I am still building a comfort/trust level. Dr. Johnson seems to listen more closely than another Dr. I've seen in the same department, and he spent more time. Though my injury is acute to my experience, it's not like I have a broken leg. So the care level is at a certain level of remove.

It was an excellent medical care

- 5 out of 5 starsReviewed on 1/8/2026
Great provider and visit, but it took almost an hour past the appointment time to be seen-that's a long time. The doctor briefly apologized when he came in to the room. I'm not at all angry about it, but it was a very long wait without much interim communication.
- 5 out of 5 starsReviewed on 1/8/2026

- 3 out of 5 starsReviewed on 9/8/2025
I think it will be easier to rate the experience once MRI results are back. One thing is that it's hard to think of all questions in such a short time and I wish I'd had the chance to discuss id knee pain could be subsidiary of preexisting hip labral tear and gait/posture problem. But otherwise it was a good interaction and I have deep respect for the doctor and his team
- 5 out of 5 starsReviewed on 9/4/2025

- 4 out of 5 starsReviewed on 8/28/2025
I had to look on my chart to see the medical term for my condition. I didn't feel like it was explained well to me due to the provider seeing I was visibly upset. He asked if I was seeing someone for professional help since I was upset.
- 5 out of 5 starsReviewed on 8/21/2025
Glad that the EPIC system works as intended. My provider had my X-ray and CT scan from another hospital system as well as my medical history and medications from my primary care physician. The system gave the provider the information needed for an effective and time efficient visit.
