My name is Ron Guay. I am a CERTIFIED FINANCIAL PLANNER™ based in Sunnyvale, CA. I work primarily with high-income tech professionals that are in the rapid accumulation phase of their financial lives (30’s & 40’s).

After spending the first 20 years of my career in financial planning & analysis roles within a large corporate setting, I made the decision to leave a strong six-figure salary and Vice President title to pursue my dream of promoting financial wellness and literacy in the community while running my own business. I launched Rivermark Wealth Management to make this dream a reality.

I look forward to working for you and your family to clarify your primary goals & values, to building a financial plan customized to your unique objectives, and to be your financial coach through all of life’s twists and turns.  

I follow a comprehensive approach to wealth management.  Similar to physical well-being, financial wellness is a result of developing and maintaining good habits and avoiding costly mistakes.  As your financial guide, I'll provide wisdom on the optimal path to achieve your goals and I'll be your accountability partner to keep you on that path and making progress.

I currently live in Sunnyvale, CA with my wife Deepti and our 3 sons.  When I'm not working, I enjoy running, cooking, and traveling.  I'm originally from Pittsburgh, PA, and still follow the city's sports teams (Go Steelers!).  In the community, I volunteer on the Cumberland Elementary School Site Council, and I enjoy coaching my kids' youth soccer teams.
