While in college, John was the President of the University of Toledo's Student-Managed Portfolio.  Upon graduation, he began his full time career in financial planning with Northwestern Mutual.

As a financial advisor, John focuses on helping successful and busy business owners, physicians, and professionals save money efficiently, protect those they love, and minimize the impact of taxes over time, in order to live the life they deserve.

John is committed to continuing his education and providing current and relevant knowledge to his clients.  John received the CERTIFIED FINANCIAL PLANNER™ (CFP®) certification. 

From the CFP® website: Most people think all financial planners are "certified," but this isn't true. Anyone can call himself a "financial planner." Only those who have fulfilled the certification and renewal requirements of CFP Board can display the CFP® certification marks, which represent a high level of competency, ethicsand professionalism. CFP Board's Standards of Professional Conduct require CFP® professionals to look out for your interests above their own.

John serves clients nationally including Ohio, Illinois, Florida, Texas, Georgia, and California.
