Bringing Together People

Our History

Where We Came From:

In 2020, Cornerstone Solutions, Inc. and Ledgerwood Associates, Inc. combined their trusted practices and 40-plus years of selling premier software solutions to the construction and real estate markets to become one entity – ETHOSystems.

Covering the Midwest, Southwest, and Rocky Mountain regions, the new entity is focused in recommending, designing, implementing, and supporting solutions tailored to the specific needs of the construction and real estate (CRE) vertical, as well as professional services.

Cornerstone Solutions, Inc. was founded in 1985 and has helped over 1,000 companies in the Midwest over their thirty-year span. As a designated Authorized Partner for Sage and honoree of the Sage Customer Excellence Award, Cornerstone focused solely on the particular needs and evolving demands of the CRE industry.

Reopened in 2009, Ledgerwood Associates, like Cornerstone Solutions, was a business lifecycle B2B service offering comprehensive Professional Services to multiple verticals.

Having met over 30 years ago, Dominic Pernai of Cornerstone Solutions and Ed Ledgerwood of Ledgerwood Associates share a camaraderie and passion for being trusted solutions providers in the construction and real estate software space. Both gentlemen have served – and are active members of – the Sage Business Partner Advisory Committee (BPAC), helping to shape the company’s strategic vision and product development in relation to channel partners’ business growth and customers’ goals.

Together, their wealth of expertise and experience are the basis for ETHOSystems, which expands their once-separate enterprises’ geographic reach and capabilities footprint to serve clients and prospects more fully, efficiently and responsively.

ETHOSystems was born of a complementary and purposeful merging of the companies. The brand promise conveys the synergy: “Quality Software and Ethical Services.” The company will continue to operate from the two locations, with the same level of professional, knowledgeable and responsive service.
