Ryan Wimmer, CPA

Ryan has worked in public and private accounting for over 15 years and has seen the inner workings of many companies in that time. His experience ranges from large, multi-million dollar private companies to publicly traded companies to non-profits to small, one man operations. As a one man operation himself, Ryan understands firsthand the need for cost-effective, valuable and simple financial help.

He moved to Denver in 2011 after growing up in the New York City suburbs. He earned his CPA while working at a CPA firm specializing in tax, audit, bookkeeping and payroll for a large number of local small businesses. After working in corporate accounting for three years in Denver, he decided to get back to his roots and provide services to the people he feels most comfortable with, the small business owner.

In his free time, he is an avid skier, rock climber, and mountaineer.
