Your SPM&Co Team

Stephan P. McMahon


Stephan has over 13 years of experience working with closely held businesses. Instinctually, Stephan founded SPM & Co to extend his passion for growing a unique and distinctive experience for those on his team as well as each of his clients. This experiential environment was designed to produce first-class results that have a positive, long lasting impact on his clients, the community, and last but not least… his team members and their families.

Stephan focuses on working with his clients to provide them with the connected knowledge and tools to make confident, strategic decisions for their companies, thus bettering their long-term success. Given the current business climate, as challenging as it is, Stephan sees it as an opportunity to bring fresh ideas and creative solutions to his clients.

Stephan grew up spending summers on the Cape with his family until they eventually made it permanent. Settling into Harwich at the start of high school Stephan quickly immersed himself in the Cape lifestyle – complete with a rusty soft–top Jeep. After graduating as a Harwich High School Rough Rider, he joined the Navy and served 8 years as an Avionics Technician, completing 3 overseas deployments all on aircraft carriers – obviously saltwater runs through his veins. During this time Stephan also earned his degrees in Business Administration and Accounting & Finance. Upon his transition out of the Navy, Stephan started his career in public accounting working for a large CPA firm in Portland, Maine until his wife decided it would be best to move back to Cape Cod to raise their young family and dig their roots into the community where they would start an accounting and advisory firm that would help small business owners in the community thrive.

Stephan is highly involved in community endeavors on the Cape. He feels strongly about leaving a positive imprint on people’s lives both through professional and personal relationships, which is exemplified by his role on the Board of Directors for the Cape Cod Chamber and as President (Past) of the Board of Directors for the Yarmouth Chamber of Commerce, as well as past and present participation in support of the YMCA of Cape Cod; Cape Kids Meals, WellStrong and the Cape Cod Challenger Club (to name a few).

Personally, as a husband and father of two, time with family is paramount. Whether it is early morning water skiing sessions with the kids, coaching just about every sport, cheering on the sidelines of every Monomoy High School field hockey game, or family hikes that magically always end at a brewery – making time for family is critical to having some semblance of balance and true happiness.

Lauren moved to the Cape 3 years ago with her husband to be closer to the water and all the Cape has to offer. When not in the office, Lauren enjoys going to the beach, getting lost in new books, and spending time with her family and friends. A serious animal lover, she recently welcomed two rescue dogs into her family, giving her two older cats a couple of new “big brothers.”
