The person, removing my staples and applying Steri-Strips could've washed their hands and wore gloves when treating me.

I have no recommendation. The doctor was excellent from surgery up through post-op appointment. His assistants, fellow doctors that were involved, all courteous and professional. I've been really happy with the outcome of the surgery and the doctor was super, super personable. And that's it. Just wanted to share that I was really happy with the doctor.

Everything was great

In the hour that I was there I had maybe 10 minutes with a live person and the other 50 minutes just sitting and waiting. That should have been a shorter time to wait

Keep clinic operation as it is now. That is why we drive 100 mi to see Dr Lonergan. Never rushes me. Excellent relief from shoulder injections
- 5 out of 5 starsReviewed on 7/24/2025
Your parking was not difficult for me. I fear the distance for some may be more of a challenge if they drive their self. I know some facilities provide valet parking for those people that have no one.

I have enjoyed my visits to this office. Very little wait time and everyone is super nice and seems to know their job responsibility. If I had to critic anything it would be to make a note on the patient's chart about what sport they play, it would go a long way with the parent that the doctor remembered it. But I know he sees tons and tons of patients
- 5 out of 5 starsReviewed on 5/25/2025
