Our History

Be the best

ERP International is commemorating its tenth year as a comprehensive science and technology solutions provider to federal agencies, providing mission services in the areas of health, national security, and defense.

In 2006, husband-and-wife team Melvin and Sandra Petty cofounded ERP with two primary objectives, to provide for their family and to solve complex business and government challenges. The team recognized the value of serving as a trustworthy partner and steward who provides counsel and thought leadership based on their real-world practical experience. The founders sought to improve their customers’ mission performance through the use of quantitatively managed processes and innovation to deliver maximized return on investment (ROI) outcomes and customer satisfaction. This successful approach resulted in a cost conscious and competitively priced partner delivering comprehensive solutions through people-focused practices. Their two-person family affair has since grown into a company of more than 450 employees across 40 satellite offices. Each and every member of the ERP team aids the company’s efforts to deliver superlative solutions, which has led to more than 300 successfully executed Federal contracts principally in highly secure and mission essential environments.

Currently, ERP supports 370 Air Force sites worldwide, and our health IT solutions affect every single member of the Air Force and Air National Guard. ERP has provided more than $3 million of annual savings to the Defense Health Agency since 2015, as well as clinical support to 360 federal organizations and 1.8 million federal workers. ERP also supports 55 U.S. Army military hospitals and 343 clinics, plus more than 300,000 U.S. Navy personnel and over 250 U.S. Navy ships.

The company has enjoyed a remarkable 41 consecutive quarters of top-line growth and profitability. Over the years, Washington Technology and Inc. Magazine have both ranked ERP among the fastest growing firms in the nation. Dun & Bradstreet’s customer satisfaction survey gave ERP a rating of 95% (putting us in the top 5% of U.S. corporations!), and ERP was recently designated as a Capability Maturity Model Integration (CMMI) Maturity Level 5 organization — a designation awarded to less than 100 US-based businesses across all sectors – demonstrating our strong commitment to providing high value and high quality services to our customers.

The Federal Government has changed a great deal over the past ten years, and ERP has been fortunate to have been positioned to have a profound impact on the transformation of agencies it serves. ERP’s co-founders remain steadfast about their primary objectives of providing for their family and the more than 1000 families connected directly to their portfolio as employees, consultants, strategic partners, advisors, and subcontractors. Our mission remains to “be the best, by delivering our best to our customers, our employees, and our communities.”
