Mike Mrozowicz

Highlands Ranch, CO 80130

As a polio survivor (1952), I would like to utilize the skills that I have developed through work and volunteer activities to find ways to improve the quality of life of those of us impacted by musculo-skeletal limitations.

 I had a 42-year career with John Deere and have extensive experience in accounting, finance, and operations.   I am a CPA and have a B.S. in Accounting and an MBA (finance emphasis).

I believe that my greatest strength is my ability to work cooperatively with others from different disciplines and backgrounds to accomplish complex objectives.

I have been married for 32 years (Lisa) and we have two adult sons (Jonathan and Ryan)
