After helping take a small startup to acquisition by a multi-billion dollar market cap company, building a successful mobile app company with tens of thousands of users, turning a failing intellectual property business into a trusted source for new research and technology, and growing a commercial products company into the US Government and Defense market, Michael Mehlberg refocused on what he loves most:

Helping small businesses owners achieve their goals and live their passion.

His approach to technology, business strategy, product development, marketing, and sales is both practical and highly effective, and has helped multiple small businesses grow into the company their small business owners envisioned. 

He co-founded Modern da Vinci to provide expertise and guidance to small business owners, who at times feel overwhelmed by all they need to know to run a small business effectively. 

Mike is an excellent manager. He worked closely with us to ensure that we had the information and resources needed to achieve the team’s goals, focusing on enabling us to do our jobs.

Mike’s leadership enabled us to consistently achieve success.
