Dental Service Organizations · Independent comparison
Independent profiles of the major DSOs.
No broker relationships. No placement fees.
Seven profiles of the dental service organizations that are actively buying practices in 2026. Contract red flags, scoring, editor notes, and the things nobody at the negotiating table will tell you out loud.
Most of what a selling practice owner reads about DSOs is written by people paid by the DSO. Placement brokers collect a commission from the buyer. Industry publications run advertorials. Bar association referral lists quote the firms that advertised that month.
There is a difference between information and marketing, and the difference matters when you are about to sign the largest contract of your career. This site is an attempt at the first one.

Why this site exists
I owned eight practices across Arizona before selling in 2026. I sat across from term sheets from several of the DSOs profiled here. I signed one of them. I also did not sign several others for reasons I wish I had known earlier. Read the full methodology.
