Sean R. MacLachlan


I specialize in business start-up, growth and transition.  From the genesis of a new idea to mergers and acquisitions of public companies, I work collaboratively with clients of all sizes at each stage of the business life cycle. Business evolves with time and growth and I feel it is important to be flexible and adaptive to support that evolution.  I enjoy assisting clients to structure and reorganize their corporate organizations, raise equity and debt capital, negotiate commercial relationships, achieve growth organically and by acquisition, achieve best corporate governance practices and transition interests to new owners when the time is right. Working with owners and executive management teams in technology, real estate development, condominium and home building, transportation and business and professional services, I seek out passionate people keen to think outside the box and change the world around us.
