Coalesce-backed Miller buys ACE to expand Mid-Atlantic reach

Miller Environmental Group, the portfolio platform backed by private equity firm Coalesce Capital, has acquired ACE Environmental Services, strengthening Miller’s footprint across the Mid‑Atlantic and adding complementary field capabilities. The deal expands Miller’s ability to bid larger, multi-site contracts and respond faster to regional demand for environmental remediation and waste solutions.

ACE, a regional provider serving commercial, industrial, marine and residential clients, brings a set of local contracts, trained crews and equipment that dovetail with Miller’s existing branch network. Company materials show Miller already operates from 30 locations nationwide; the integration of ACE’s assets will deepen capacity in key Mid‑Atlantic corridors and shorten response times for customers facing regulatory or operational incidents.

Robb Schreck, chief executive of Miller, described the move as a tactical enlargement of service scope and operational reach. He emphasised that the acquisition is intended to produce cross-selling opportunities across industrial cleanups, emergency response and ongoing waste management services, while preserving the local management expertise that clients rely on.

From ACE’s side, General Manager Tim Wise framed the transaction as a way to join a larger platform without sacrificing the team culture and service standards that built ACE’s regional reputation. Employees and customers should see continuity in day‑to‑day operations alongside access to a broader suite of technical services and capitalised resources under Miller.

Coalesce Capital, which manages more than $1.6 billion in assets according to its disclosures, said the acquisition aligns with a broader roll‑up strategy to assemble a vertically integrated environmental services group along the eastern seaboard. JJ Hearty, Coalesce’s head of business development, noted the firm is executing a disciplined consolidation play to scale field services and improve bidding competitiveness for municipal and corporate contracts.

Operationally, Miller and ACE plan a phased integration intended to keep service continuity while aligning pricing, safety and billing systems. Market watchers will be watching whether this and similar deals accelerate a wave of platform expansions in the environmental services sector as PE sponsors seek scalable, service‑led growth.
