About Me

We organize & help operate businesses and estates with trust, respect, & teamwork.

For more than 25 years, I have helped clients take strategic approaches to their business needs. In my experience,too many businesses try to self-diagnose solutions to their problems, resulting in overemphasizing management and under-emphasizing leadership. This approach is more about control push rather than stewardship pull.

My role, as one of your team players, is to facilitate problem solving using a multi-step consulting process to create change, as well as overcome technical and adaptive challenges to shape your future strategy.


* Business law. Entity formation, commercial contracts, complex transactions.
* Intellectual property. Trademark, copyright, trade secrets.
* Estate and tax planning. Wills, trusts, probate administration.
* Transformative change. Strategic planning, education, compliance programs.

  • Michael Charles Doland

    Many Avvo attorneys give accurate answers but what distinguises Mr. Guay is the "practical" nature of his suggestions which accompany his answers. If I were a client I would want this quality in my lawyer, not just being correct, but advice that balances the costs and benefits of being "right" versus the exploration of alternatives that can accomplish the same goals. Bravo!

  • Dorothy G Bunce

    Mark Joseph Guay has a deep understanding of business & contract law which means he understands that there are often no easy or simple answers. Bad if you want a lawyer to tell you what you want to hear, but good if you want a lawyer to keep you out of court. I am happy to endorse Mr Guay here on Avvo.
