02Healthcare-only

A narrow mandate buysa shorter learning curve.

Seventeen years
One sector
No exceptions

Every generalist fund that has lost money in healthcare lost it the same way. Not on the growth rate — on a billing practice that was compliant in one state and not in another, on a payor contract that reset three months after close, on a physician compensation model that could not survive being renegotiated.

Those are not tail risks. They are the ordinary operating reality of the sector, and the only defence against them is having seen them before. We have run a corporate integrity agreement to completion. We have taken two platforms through a payor termination and out the other side. We have rebuilt a revenue cycle that was eleven months behind.

So we do not diligence a healthcare business the way a generalist does. The clinical quality review happens before the quality of earnings, because a platform with a bad outcomes profile is not cheap — it is unbuyable. Our chief medical officer sees every deal in week one, and has killed four of the last nineteen.

“A generalist could learn every bit of this. It would cost them roughly four hundred million dollars, which is about what it cost us.”

03Operating

Four functions we staff ourselves,because outsourcing is how platforms stall.

41 operators
on the central team
Compliance9 people · led by a former OIG counsel
Coding audits, Stark and Anti-Kickback structuring, state licensure, and the unglamorous work of documenting that a referral relationship is what the platform says it is. Two of our platforms arrived with an open corporate integrity agreement; both closed them out on schedule.
  • Quarterly coding audit, every site
  • State licensure calendar held centrally
  • Pre-LOI regulatory screen on every add-on
Revenue cycle17 people · Chicago and Tampa
Claims, denials, payor contract benchmarking and the collections tail. Where we have taken a platform's revenue cycle in-house, days in A/R have fallen by a median of eleven days in the first year. It is the single largest source of value we create, and the least interesting thing on this page.
  • Median days in A/R at exit: 32
  • Denial rate target: under 4%
  • Payor rate benchmark refreshed twice a year
Clinical6 people · CMO, two CNOs, three quality leads
Outcomes measurement, HEDIS and star-rating performance, incident review, and the clinician relationships that determine whether a platform can recruit. Clinicians stay because other clinicians are running the clinical side, not because a spreadsheet told them to.
  • Clinical review before quality of earnings
  • Outcomes reported to the board quarterly
  • No non-competes for clinical staff below director
Mergers & acquisitions9 people · proprietary sourcing
A standing pipeline per platform rather than a banker-led process per deal. Roughly 110 letters of intent a year across the portfolio, of which about 21 close. Add-ons are underwritten to what the platform can absorb in a year.
  • 168 add-ons closed, 2018–2026
  • Median add-on: $1.9M EBITDA
  • Integration capacity is what binds, and it is not capital

04What we buy

Stated plainly,so nobody spends a month finding out.

Control only
No minority positions
Platform EBITDA
$5M to $40M, with a defensible run-rate and a close that can survive an auditor.
Add-on EBITDA
$1M and up, in a therapeutic area where we already hold a platform. We do not build a platform out of add-ons alone.
Structure
Control and majority recapitalisations. Sellers roll 10–25% in every deal we have done since 2014.
Therapeutic areas
Behavioral health, musculoskeletal, post-acute, laboratory, dental, women's health and the health-IT that serves them.
Payor mix
Commercial-weighted preferred; we will underwrite a government-weighted book where the rate environment is legible.
Timing
Indication within 10 business days of a CIM. Clinical review inside three weeks. Signed in eight.

If you built the practice

You will talk to the same two people from the first call to the second anniversary. We will tell you in the first meeting what changes for your clinicians and what does not, and we will put it in the letter of intent rather than leaving it as a promise. Sellers roll alongside us in every deal, which is the only guarantee that actually means anything.

Start a conversation

If you are running the process

Indication in ten business days. Clinical review inside three weeks. We have not re-traded a signed letter of intent on a regulatory finding since 2016.
