Call-prep brief

Background

  • 25+ years in healthcare services, health plan operations, and capital markets
  • 17 years at Goldman Sachs (Investment Banking division) advising on major healthcare transactions
  • CFO of Humana from 2014, overseeing primary care businesses and driving strategic transformation
  • EVP and President of Aetna at CVS Health (Sept 2023–Aug 2024), leading a segment serving ~35M members
  • Departed Aetna in August 2024 after CEO Karen Lynch cited financial performance below expectations amid a Medicare Advantage cost spike (MLR jumped to 89.6%)
  • Named Senior Advisor to WCAS's Healthcare Group in July 2025

Current Focus

  • Advises WCAS on complex, creative partnerships across the healthcare ecosystem — payer, provider, and services intersections
  • Sits on nonprofit/industry boards, including the New York Historical Society

What He Cares About

  • Payer economics and MLR discipline — the dynamic that ultimately cost him the Aetna job
  • Primary-care and physician-practice operating models, drawing on his Humana oversight of primary care
  • Capital markets and deal structuring, rooted in his Goldman Sachs background

Sensitivities

  • His Aetna tenure ended abruptly after 11 months amid a public earnings miss — avoid framing questions as "why were you let go"; keep discussion forward-looking
  • May be guarded discussing CVS/Aetna internals given the recent, public nature of his departure

Questions to Ask

  1. What underwriting/MLR lessons from Aetna's 2024 Medicare Advantage miss should a physician-practice roll-up build into its underwriting?
  2. Which primary-care/value-based models from his Humana tenure translate best to a roll-up thesis?
  3. Who in his Goldman/Humana/Aetna network would he introduce for platform or bolt-on diligence?

Outreach draft

Subject
Physician Practice Roll-Up Diligence — Quick Call?
Brian, Congratulations on your new advisory role with Welsh, Carson, Anderson & Stowe. Your run leading Aetna's payer segment and Humana's primary-care strategy as CFO gives you a rare vantage point on where physician-practice economics are heading, especially with Medicare Advantage cost pressure reshaping the market. We're doing diligence on a physician-practice roll-up thesis and would value 20 minutes of your perspective on payer contracting dynamics, primary-care unit economics, and where you'd underwrite risk differently today. Happy to work around your schedule. Would you be open to a short call in the next couple of weeks? Best, [Your Name]
