As a Jacksonville fee-only financial planner, I like to use straightforward communications techniques to distill complex financial topics into layman's terms. I have found that understanding your plan and your investment strategies leads to confidence - which leads to financial success. It is difficult to be confident in a plan or a strategy that no one understands. - Jon Castle, MSFS, CFP®
"Our Job is to make YOUR Job... OPTIONAL!"

Jon Castle is a Jacksonville, FL fee-only financial advisor. He is a managing partner in Paragon Wealth Strategies, a wealth management, financial planning and investment advisory services firm that helps individuals, families and business owners grow their assets for retirement, protect their assets during retirement, and minimizes their taxes throughout.
More specifically, Paragon is a deep expertise, high touch, boutique wealth management firm that helps ordinary people become millionaires and millionaires become multi-millionaires. Unlike most firms, we work as a team and bring a high level of expertise across multiple disciplines to our clients dependent on their situation.
EINSTEIN SAID, “IF YOU CAN’T EXPLAIN IT SIMPLY… YOU DON’T UNDERSTAND IT WELL ENOUGH.”
THAT’S JON’S MOTTO.
Jon specializes in working with those who are at or nearing retirement. Common issues he solves for his clients include:
- When can I retire?
- How much do I need to retire?
- How do I get health insurance if I retire early?
- How can I minimize taxes in retirement?
- What is the best social security strategy - for me?
- How should I invest in retirement?
With over 25 years of experience in financial planning, investment management, and working directly with retirement age clients, Jon Castle believes a simple, straightforward way of explaining things (often with upside-down drawings) can help clients be more successful because they understand their strategies, make decisions confidently, and then go on to focus on what’s really important in their lives - enjoying retirement and family.
Jon graduated in 1989 from the United States Military Academy at West Point and served as an Armored Cavalry officer and helicopter pilot in the U.S. Army until he entered the financial services industry in 1995.
He is a CERTIFIED FINANCIAL PLANNER™ professional and holds a Master's Degree in Financial Services (MSFS). In addition to setting the strategic direction of the firm and chairing our Investment Committee, Jon specializes in estate planning (Wealth Transfer) concepts. Jon was the author of the Community Column “WealthGuards” for the Florida Times-Union, has been featured in Kiplinger, on WOKV and Fox4, the Jacksonville Business Journal, was the co-host of the call-in financial talk radio show, “Financial Feud,” and is an instructor for "The Retirement Continuum" course held bi-annually at the University of North Florida. He has also been a guest lecturer on wealth preservation topics at the Florida Coastal School of Law and on business aspects of the financial industry at large at the University of North Florida.
Mr. Castle is a former member of NAPFA and a current member of the Financial Planning Association (FPA). He grew up in Virginia, is married, and has two adult children. In his free time, Jon enjoys activities with his family, mountain hiking, running his spec Miata on a racetrack, paddleboarding, walking the beach with his wife (no, really, it’s true), and riding his Harley (whose name is Clyde). He also studies and practices the Leung Sheung lineage of Wing Chun Kung Fu. Occasionally, he hits the gym or goes running and complains about it afterward.
We founded PARAGON Wealth Strategies with the goal of creating a cost effective alternative to the abuses, conflicts of interest, inexperience, and poor levels of service that many clients report they receive at the leading Wall Street firms or retail outlets. We strive to be the optimal financial firm for clients who desire objective, holistic wealth management, without proprietary influence, delivered by a team of highly credentialed financial professionals who care about them as individuals. Professional excellence, concern, sensitivity, and diligent oversight are PARAGON’s core values.
Our Commitment to you is one of honesty and service. We have an unmatched capacity for hard work, and a down-to-earth, practical approach with pragmatic advice intended to maximize your odds of achieving your goals. We recognize that you have worked hard developing your own career; we work equally as hard developing ours. We are committed to enabling our clients to enjoy their lives while their financial affairs are managed by an independent, credentialed, objective team of professionals who can bring nearly every financial resource to the table in support of that goal.
Please Note: PARAGON does not offer HOURLY rate services or "one-off" financial plans for a one-time project fee. PARAGON Wealth Strategies provides comprehensive wealth management services - including all investment management, financial planning, tax planning, estate planning, and retirement income planning as a core offering of a comprehensive wealth management relationship.
After offering an hourly fee option in the past, and watching those clients struggle and lag behind our other clients in virtually every area of financial success, we eliminated that service option. In our opinion, the hourly model and "one-off" financial plans significantly distracts our team's focus from delivering an extraordinary service and investment experience to all clients, all the time.
Please visit PARAGON's website for a detailed discussion of service models available.
