SOUTHLAKE, TX / March 9, 2023 / Allied OMS – a doctor-owned, led, and governed management services organization (MSO) in the oral and maxillofacial surgery space – is pleased to announce that Advanced Oral and Maxillofacial Surgery, Oregon Oral Surgeons, and WestsideOMS have joined its growing network of top-tier OMS practices, expanding the footprint of Allied OMS’ Doctor Equity™ model in Colorado and Oregon.

“At Allied OMS, we’re committed to providing better alignment of interests, better economics for our surgeon partners, and better transparency into the MSO business model,” said Ryan Graham, COO at Allied OMS. “We’re pleased to share our Doctor Equity™ model with these best-in-class practices and look forward to helping them achieve their goals.”

“We had been approached by several different groups and ultimately decided the Allied OMS model was the right one for us,” said James Lessig, DDS, who leads Advanced Oral and Maxillofacial Surgery in partnership with Thomas Michalik, DMD, MD. “A doctor-governed organization means that we will retain clinical and cultural autonomy at our practice. Allied OMS’ doctor-led board of directors will always put the doctors first.”

Oregon Oral Surgeons, WestsideOMS, and Advanced Oral & Maxillofacial Surgery are the latest practices to join Allied OMS, the only doctor-owned, doctor-led, and doctor-governed MSO in the country. For more information on Doctor Equity™ and gaining Power Through Partnership™, visit

“Partnering with Allied OMS puts me at the helm of my financial future,” said Todd Tucker, DMD, MD who leads Oregon Oral Surgeons alongside Bryan Williams, MD, and Brian Allender, DMD. “I’ll get all the benefits of a large organization – better contracts, negotiating power, and a network with which to share best practices, without exiting too early or at too low of a multiple.”

“It was important to me to pick a partner that shared my long-term vision for my practice,” said Rupi Dhadli, DDS, MD, of WestsideOMS. “Allied OMS’ unique Doctor Equity™ model ensures that everyone’s interests are aligned as we work together to secure a better future for my practice and my patients.”

With the addition of these three practices, Allied OMS now has a network of 46 doctors, serving patients out of 50 locations across 10 states, including California, Colorado, Louisiana, Maryland, Michigan, New York, Oregon, Tennessee, Texas, and Virginia.
