Callard and Cowdery

For over twenty-five years John Cowdery has been creating value, improving operations and guiding the growth of successful environmental services firms.

Today he’s sharing his vast industry knowledge, connections and proven methods to help business owners meet their objectives – growth, improved financial performance and operations, succession, or acquisition.

Passionate about the quality and preservation of our natural resources, John has built businesses that not only succeed financially, but succeed in advancing their founders’ visions and ideals.

At Hygienetics a Boston based consulting firm, John grew the firm’s West Coast operations from six to 120 people in 18 months, opening and running West Coast offices in San Francisco and Orange County.

At ATC Group Services, he ran West Coast operations, growing the  division through organic growth and strategic acquisitions from $7mm to over $30mm in annual revenues.

In 2000, Jones & Stokes hired John to be CEO and lead the company through an operational turnaround including streamlining of back office procedures, new operational programs, and business development designed to stabilize and grow the firm while planning for ownership succession and acquisition. During his eight years there he grew the firm through acquisitions and organic growth from four offices to 23, and from $22mm to over $75mm in revenue with annual growth of 15%. In 2008 he orchestrated Jones & Stokes sale to ICF.

Above all, John brings a straightforward, practical, efficient communications and consulting style – no learning curve – that quickly produces decisions, actions and results. He’s an effective sounding board for the toughest questions and issues. And rather than peering over an owner’s shoulder, John stands shoulder-to-shoulder with his clients, ready to roll up his sleeves to help execute these business-changing strategies.


"We brought John in to manage a board requested internal review of all financial and operational systems. This review has proven to be a tremendous value, creating a multi-million dollar cost savings initiative that has placed us on track to have one of the most profitable years in company history. His seasoned leadership skills and ability to focus on "results oriented" activities helped to make this a relatively short project, providing results that commonly would not be realized for months with a traditional consulting firm."
