Sonoma Capital has named Martin Gagnon president, effective July 1, 2026. Gagnon succeeds Michael Dubowec, who has moved into the role of special advisor to the president while continuing to serve on Sonoma’s board of directors and as a founding shareholder. Sonoma has also promoted Mathieu LeFebvre to vice president, sales.
Gagnon joined Sonoma at its inception as the company’s founding sales leader and has played a central role in building its origination platform, expanding its market presence and driving business development across the organization. As president, he will lead Sonoma’s continued growth while building on the strong foundation established during the company’s first four and a half years.
“Martin has been instrumental in Sonoma’s success from day one,” Randy Smyth, CEO of Sonoma Capital, said. “He combines strong leadership, deep industry expertise and a clear vision for the future. The board has tremendous confidence in his ability to lead Sonoma through its next chapter, and we believe the company’s best days are still ahead.”
Dubowec led Sonoma to nearly $300 million in assets under management in just over four years. Beyond the company’s growth, he helped build the team, culture and values that continue to define Sonoma today.
“Michael’s contribution to Sonoma extends far beyond the growth of the business,” Smyth said. “He helped build an exceptional organization and a culture that continues to set Sonoma apart. We are grateful for his leadership and pleased that Sonoma will continue to benefit from his experience, insight and guidance in this new role.”
As special advisor to the president, Dubowec will continue supporting Sonoma’s long-term growth and strategic priorities while remaining actively involved as a board member and shareholder.
Sonoma has also promoted Mathieu LeFebvre to vice president, sales. LeFebvre has been a key contributor to the company’s growth and has consistently demonstrated strong leadership, deep industry expertise and a commitment to both clients and colleagues. In his new role, he will lead Sonoma’s sales organization and play an important part in executing the company’s next phase of growth.
“We enter this next chapter from a position of strength,” Smyth said. “We have an exceptional team, a growing platform and a clear vision for the future. I am excited about what lies ahead for Sonoma.”
