Michelle Ash CFP®, RICP®, CASL®

Michelle Ash believes a financial planner’s perspective should be holistic, by taking a total wealth management perspective that allows clients to factor their goals, values, and priorities into their situation.  Critical to a client's success is the integration of planning to address some of retirees' greatest worries:  health care expenses, weathering the market’s ups and downs while using a portfolio for income, minimizing taxes, to name a few.  This approach is what she brings to The Retirement Continuum™ courses to help attendees maximize retirement success.
