PSST Continues Strategic Nationwide Expansion with Acquisition of California-Based ACA Compliance Solution Services

Adds Western Customer Base and Premier Broker Network

LOUISVILLE, KY / ACCESS Newswire / October 21, 2025 / PSST, providers of integration and compliance SaaS solutions for efficient organizational management, announced today the acquisition of ACA Compliance Solution Services (ACA CSS), a Woodland Hills, California-based leader in Affordable Care Act compliance. ACA CSS supports private sector companies nationwide, with a particularly strong customer base in the Western U.S. Through a previous acquisition PSST gained an established presence in New York, Ohio and Connecticut. Now with the addition of ACA CSS, PSST’s strategic expansion has spanned westward – reaching some of the most attractive markets in America.

A Legacy of Excellence

The dynamic father-and-son team of Glenn Davidow and Michael Davidow has built ACA CSS into one of the most recognized and respected brands in the industry. ACA CSS has evolved to offer a full suite of ACA compliance solutions, including 1094/1095 compliance, ERISA Wraps, and Form 5500 filings. Consistent with PSST’s model, ACA CSS augments its solutions with white glove customer service.

This acquisition ushers in an exciting new era for ACA CSS – Glenn will remain closely engaged with the company as a strategic consultant, while Michael ascends to a leadership role within the PSST platform.

Market Strength Through Unification

Now in its seventh year under PennSpring Capital ownership, PSST continues to leverage its industry expertise and PennSpring’s capital base to pursue additional acquisitions of complementary ACA and HR compliance solution providers.

“It is gratifying to be truly inspired by a founding team, as we have been with the Davidow family and ACA CSS,” stated PennSpring Managing Partner Lou Castelli. “In an industry increasingly driven by broker relationships, ACA CSS brings to PSST a broker network without peer. We are excited to combine resources and increase market share across the critical Western U.S.”
