Louie Lee founded Lockstep Partners in 2026 after twelve years executing transactions in private equity, investment banking and, for most of that time, inside private-equity-backed services platforms.
He has led M&A at six sponsor-backed platforms: Commonwealth Island Capital (Argentum and ACI), a law firm MSO focused on personal injury; StrideCare (Webster Equity Partners); GI Alliance (Apollo), where he led 23 platform and add-on transactions before the majority sale to Cardinal Health; RAYUS Radiology (Wellspring Capital), where he ran a 11-site de novo program; Unifeye Vision Partners (Waud Capital); and Caregiver, Inc. (DW Healthcare Partners and Council Capital), through its 2020 sale to WindRose Health Investors. At four of them he was the first M&A hire and built sourcing, diligence and integration from zero.
Earlier, he advised on private equity secondaries, including LP portfolio sales and a GP-led transaction, at Greenhill & Co.; covered industrials clients in investment banking at UBS, where he closed a lead-left acquisition financing; and worked in private equity at Graham Partners.
