"I love jazz and, like the jazz greats, an entrepreneur has to be ready to improvise. It’s a privilege to help an entrepreneur create a great business that looks little like the business the entrepreneur first thought he or she was creating."

Jim is a partner in HMB’s Business and Finance Group. He focuses his practice on start-up and early stage financings, mergers and acquisitions, contract negotiation and providing counsel to company executives and their boards of directors.

Jim represents businesses from their beginnings through initial financing, growth initiatives, subsequent financing and ultimate liquidity. While a large portion of Jim’s practice is centered in the technology space, Jim also represents entrepreneurs who seek to purchase, operate and grow established businesses in areas such as marketing, packaging, manufacturing and distribution.
