Our History

Built on Experience. Evolving With Purpose.

SAI’s history reflects steady growth, long-standing relationships, and a commitment to serving customers well as markets and technologies evolve. From our beginnings as a manufacturer’s representative in Ohio to our current regional footprint, each chapter of our story has shaped how we support engineers, contractors, and building owners today.

The Story of SAI

A sepia-toned vintage photograph showing a group of men wearing suits and name badges, walking along a sidewalk. They appear to be attending an event or meeting. In the background, there is a small hut-like structure, some trees, and a fenced area with parked cars.

1962 — The Beginning

Roger Anderson founded RG Anderson as a Manufacturer’s Representative.

1982 — New Partner

Steve Gammeter joined Roger Anderson and his son, Nick Anderson, as a partner of RG Anderson.

Four men in suits gathered on stage during a business award ceremony. Three of them are holding a trophy while smiling. They appear to be in a celebratory mood as they stand close together in a spotlight.

1999 — The Merge

RG Anderson in Cincinnati merged with Stoermer Equipment Company in Dayton and became Stoermer-Anderson, Inc., allowing the company to open an office in Columbus and expand into central Ohio.

2013 — New Acquisition

Stoermer-Anderson acquired JH Ballenger Co., gaining the expertise of their sales and service staff and adding Cleaver-Brooks to the Stoermer-Anderson line card. This broadened the market to include a large portion of Kentucky and led to the opening of the Louisville branch office.

2014 — Ownership Transition

After the passing of co-owner Nick Anderson, Steve Gammeter assumed sole ownership of Stoermer-Anderson.

2018 — New Owners

Lisa Hatfield, Keith Walters, and Tom Schimdt became the new owners of Stoermer-Anderson.

2022 — Change in Leadership

Tom Schimdt retired, shifting leadership to Lisa Hatfield and Keith Walters.

2024 — New Headquarters

Stoermer-Anderson headquarters relocated to Blue Ash, Ohio, to support continued growth.

The building has modern architecture with a large windowed facade. Partner logos such as CleaverBrooks, Armstrong, and others are visible at the bottom.

2026 — A Fresh Look

Following a name and logo update, Stoermer-Anderson is now SAI, and launched a new website in 2026 to better serve customer needs.

Looking Ahead

While SAI’s name and footprint have evolved over time, our focus has remained consistent: representing trusted manufacturers, supporting applied systems, and building long-term relationships with the people we serve. As we move forward, we remain committed to adapting thoughtfully while staying grounded in the experience and values that have guided us for more than six decades.
