Meet the rest of the team

Ryan Hutchins

President, Valuation

Ryan founded Peak Business Valuation, a national firm that delivers 1,100+ business valuations and 150+ equipment appraisals a year. He works with business owners who are buying, selling, or growing — and need to know what they actually have. His focus is quality, accuracy, and making sure the number means something.

Jason Parr

President, Sales Tax

Jason has spent 30 years going deeper into one discipline while most firms go broader. He joined Peisner Johnson in 1996 and built his career there learning every service line, working through every kind of situation, and eventually becoming President and CEO. The Sales Tax People has completed 35,000+ projects for companies ranging from regional mid-market businesses to large multinationals. His clients are CFOs, controllers, and the accountants who serve them, usually calling when the exposure has already been building quietly for months. He'd rather you call before that point.

David Mink

President, Marketing

David founded Avalaunch Media in 2012 and built it into one of the fastest-growing marketing agencies in the country: 50 people, 8 figures, clients like Red Bull, GoPro, and Microsoft. After working with hundreds of companies, he kept seeing the same pattern: businesses with a real marketing leader get results. Those without one waste time and money. That's why he built the first fractional CMO, agency-backed solution and why he joined Ampleo.
