In the exam room
We decided the embarrassment was the enemy.
This hangs in the exam room. It is the first thing patients see, and it does the one thing a physician’s office usually forgets to do: it tells you that you are allowed to feel human about this.

How it works
A surgeon who wants to help you avoid surgery.
The procedure room is down the hall from the consultation room. For most of what we treat, that is the whole journey.
- No general anesthesiaTreated under local anesthetic, in the office.
- No hospitalYou walk in and walk out the same afternoon.
- No prescription pain medicationMost patients need nothing stronger than over-the-counter pain relief.
- Back the next dayMost patients return to work, life, and sport the next day — typical, not guaranteed.
