This representation includes flexible billing arrangements that allow for hands-on legal representation with a limited budget. We have assisted with the formation and growth of businesses in software, medical services, professional services, medical devises, robotics, real estate, manufacturing, on-line and traditional retail, as well as forming and guiding non-profit organizations.

Mergers and Acquisitions

Our experiences with early stage and developing companies helps us understand the process needed to move from development to preparing for a sale or other major financial event. We recommend a process to get ready for a sale or other financing. We have helped the owners in successful sales of technology businesses, engineering, law, medical, oil field and insurance services, as well as manufacturers and distributors of various products. Of course, we also assist buyers or investors with the understanding of what the sellers have gone through or are going through. This includes reviews of issues that could kill a deal or make the investment more risky. We assist with a strategy for reducing that risk. When specialized legal or other professional services are required, we assist by locating and monitoring other professionals to help get the deal done.
