Partner Named to 2019 Inc. 5000 List of Fastest-Growing Companies

Ranks #4829 overall, #42 in environmental services

Partner Engineering and Science Inc. (Partner), a national engineering, environmental and energy consulting and design firm headquartered in Torrance, CA, has been named as one of Inc. 5000’s Fastest-Growing Private Companies in America for 2019. Partner ranked #4829 overall, while also ranking #42 in the Top Environmental Services category. The award-winning firm attributes this honor to its hard-working team members and their steadfast commitment to being a widely-recognized and trusted brand in the due diligence and commercial real estate industries.

The annual Inc. 5000 list is the most prestigious ranking of the nation’s fastest-growing private companies. The list represents a unique look at the most successful companies within the American economy’s most dynamic segment—its independent small businesses. Microsoft, Dell, Domino’s Pizza, Pandora, Timberland, LinkedIn, Yelp, Zillow, and many other well-known names gained their first national exposure as honorees on the Inc. 5000. This is Partner’s fifth time on the Inc. 5000 list, an honor bestowed to only 4% of all private companies.

“The companies on this year’s Inc. 5000 have followed so many different paths to success,” says Inc. editor in chief James Ledbetter. “There’s no single course you can follow or investment you can take that will guarantee this kind of spectacular growth. But what they have in common is persistence and seizing opportunities.”

Not only have the companies on the 2019 Inc. 5000 list been very competitive within their markets, but the list as a whole shows staggering growth compared with years prior. Partner has experienced a three-year growth trajectory of 57%.

“We are extraordinarily proud to be recognized on the Inc. 5000 list for the fifth time,” says Partner CEO Joseph P. Derhake, PE. “Our core, market-leading practices continue to experience steady growth, while our newer, entrepreneurial practices are experiencing meteoric growth. This honor is a testament to our continued goal of providing exceptional cross-disciplinary services for our commercial real estate clients and being the home for the most talented professionals in our field.” 

With global headquarters in Los Angeles and East Coast headquarters in Eatontown, NJ, Partner continues to expand its presence with over 800 employees and 43 offices worldwide.
