About Us

  • John Hannah, CFP®, CPA


    John is a licensed Certified Financial Planner® (CFP®) and a CPA (although he no longer practices public accounting). John spent a decade in public accounting during the 1990’s, working with individuals and business owners. While specializing in personal taxation, he found that many of his clients sought financial planning advice from a trusted source. John became licensed as a Certified Financial Planner® in 1998 and started his own financial planning firm shortly thereafter. His strong background in personal taxation is an excellent complement to his knowledge of investments, insurance, and estate planning.
