Why they matter

A repeat physician-rollup operator who just closed his first institutional capital raise, actively expanding a doctor-led OMS platform state by state.

Background

Daniel (Dan) Hosler comes from a healthcare family (his mother a nurse anesthetist, his father founder of an ambulatory surgery center and GI practice), earned a BA in Biochemistry from Rice University and an MBA from Northwestern's Kellogg School, and started three companies before business school. He spent 15+ years in private equity, including as a principal at Sterling Partners leading M&A for its Great Lakes MSO eye-care rollup (10 deals in under two years), before co-founding DuneGlass Capital, a lower-middle-market healthcare PE firm where he is Managing Partner and chairs the investment committee. In 2020 he founded Allied OMS, a doctor-owned, doctor-led MSO platform for oral and maxillofacial surgery practices, which now supports 50+ locations across 14+ states.

  • 2017
    As principal at Sterling Partners, led formation of Great Lakes MSO with Grand Rapids Ophthalmology, an eye-care practice rollup where he closed 10 deals in under two years

Call-prep brief

Daniel (Dan) Hosler, Founder & CEO, Allied OMS

Background

  • Healthcare family roots (mother: nurse anesthetist; father: ASC founder/GI practice owner)
  • BA Biochemistry, Rice University; MBA, Kellogg (Northwestern)
  • Started three companies pre-MBA; 15+ years in PE
  • Principal at Sterling Partners, led M&A for Great Lakes MSO eye-care rollup (10 deals in <2 years)
  • Co-founder/Managing Partner, DuneGlass Capital (chairs investment committee)

Current focus

  • CEO of Allied OMS, a doctor-owned/doctor-led MSO for oral and maxillofacial surgery, founded 2020, now 50+ locations across 14+ states
  • Just closed first institutional capital (65 Equity Partners + Everberg Capital, June 2025)
  • Actively expanding into new states (e.g. Indiana via Oral Surgery Michiana, 2025)

What he cares about

  • Doctor-majority governance, shared economics between capital and surgeons
  • Positions Allied OMS as an alternative to "conventional MSO" roll-up models
  • Prides the platform on low leverage relative to peer DSOs/MSOs

Potential sensitivities

  • Just took first institutional money. May be guarded about further outside capital or control questions this soon after the raise
  • Strong public stance against traditional PE extraction models; approach any pitch through a doctor-alignment lens
  • Runs two overlapping roles (Allied OMS CEO + DuneGlass Managing Partner), clarify which hat is relevant to your ask

Questions to ask

  1. How is the 65 Equity Partners/Everberg capital being deployed, organic buildout vs. bolt-on M&A pipeline?
  2. Given the Great Lakes MSO precedent, does he see OMS consolidation following the same multi-year rollup trajectory as eye care?
  3. How does DuneGlass's thematic healthcare-services thesis inform which new states/specialties Allied OMS targets next?

Outreach draft

Subject
Physician rollup playbook, quick call?
Hi Dan, I've been following Allied OMS's growth, the doctor-led governance model plus the recent 65 Equity Partners/Everberg raise is a compelling structure in a crowded MSO space. Your earlier work scaling Great Lakes MSO in eye care and now building a similar platform in OMS gives you a rare repeat-founder view on physician practice consolidation. We're doing work in the physician practice rollup space and would value your perspective, on deal sourcing, doctor alignment structures, and where you see the next wave of consolidation heading. Would you have 20-30 minutes for a call in the next couple of weeks? Happy to work around your schedule. Best, [Placeholder Name]
