Edward Cahill, CPA
Ed grew up in small-town Iowa and received a bachelor’s degree in Accounting and Economics from Iowa State University. Ed’s post-college career before moving to Boulder included a position in the auditing department of a Chicago bank and CPA/Audit Manager with a regional Iowa CPA firm.

Ed’s goal is to provide meaningful and cost-effective assistance in coordinating client's short-term tax and accounting demands with longer-term planning considerations. This often involves collaboration with financial and legal advisors. 
Ed and his wife Sherry spend lots of time with their three grown children and two grandsons.. Ed is a fair-weather hiker, biker, camper, skier and feels fortunate to live in Colorado which provides many days of great weather to enjoy these activities.
