John LeMieux

John LeMieux, Co-Founder & Principal

"To best assist my clients with complex financial decision making, I believe I need to address the multifaceted realities of life that underscore the financial facts. My experiences as an entrepreneur co-founding Anton LeMieux Financial Group, a financial planner, and an investment advisor have combined to guide me in identifying the unique financial needs of each individual, family, family-owned business, and nonprofit organization that I serve. Working alongside my clients to more thoroughly understand their needs, I can create the best plan to meet them.

"I know that the realities of life can impact our personal goals and, potentially, our overall financial outlook. After a reoccurrence of liposarcoma, I lost my left leg to cancer. Having faced such a challenge, I don’t shy away from conversations with clients that might become more personal or even emotional. I know these discussions and the details they provide are important to the success of the work we do together.

"In the process of designing a financial plan, my clients and I discuss their own realities. It’s this depth of conversation that helps me create their best holistic financial plan and bring to it the strategic value and client advocacy that our firm was built to offer."
