John’s interest in the financial services industry can be traced back to his college days when he earned bachelor's degrees in both finance and human development and family studies, followed by a master's degree in finance. He wanted to understand the key aspects of the financial lifecycle and integrate financial discipline to assist individuals in successfully planning for those events.

His focus is to provide all clients with superior service by understanding their needs and providing relevant information in an easy-to-understand format.

Donald F. Oatley, CPA, PFS, Business & Investment Consultant Don Oatley

Business & Investment Consultant

Don moved full-time into investment advising after selling his mid-size CPA firm in 2001. With over three decades of experience as a certified public accountant and fifteen years of experience in the financial services industry, Don’s experience as both a trusted CPA and financial advisor positions him to help clients chart a sustained and profitable course of secure investing.

 

As a CPA, Don assisted clients through many difficult lifecycle challenges such as business downturns, divorce, family estate issues, the death of a spouse, and retirement issues, among others, so he understands the relationship between investing and financial security. Don’s philosophy of “Value Investing” (buying quality investments at discounted prices) has helped grow his clients’ assets while minimizing their risks.

 

Don has been active in the Colorado Society of CPAs (CSCPA) as a member of the board of directors and as vice president. He is a member of the financial planning committee and has helped implement personal financial planning and investment conferences sponsored by the CSCPA.

 

Don served in the U.S. Navy as a Naval Flight Officer, saw service in Vietnam, and retired from the Naval Reserve with the rank of Captain. When not engaged in his passion (investing his and his clients’ money), Don enjoys spending time with his three grandchildren, fly fishing, hiking, trap shooting, and traveling.
