Paul St. Onge

Founder & Financial Advisor

After five years as a high school teacher and coach, Paul began his career in the life insurance industry at age 29 alongside his wife, Anne, while raising their two children, Bryan and Amy. Fourteen years later, with their family expanded to include Jeff, Christopher, and Matthew, Paul sought greater independence and the ability to build a truly client-centered practice while maintaining the family balance that mattered deeply to him. With Anne serving as his administrative assistant, he joined Commonwealth Financial Network, drawn to the firm’s simple but powerful philosophy of “help advisors to help their clients”. The focus of working with clients to help them achieve their goals and navigate their financial life with confidence and clarity is at the core of Paul’s approach.

In 2017, Paul’s son, Matthew, joined the practice after graduating from the University of New Hampshire Paul College of Business and Economics, helping ensure continuity and long-term support that clients fully deserve.

Paul is a graduate of University of Massachusetts Amherst and holds FINRA Series 6, 22, 26, 62, 63, and SIE registrations. He is also an Investment Adviser Representative with Commonwealth Financial Network.
