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.

    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]
