Mary Wyman


Mary Wyman maintains a practice focused on corporate advisement and commercial litigation. Mary’s goal is to provide a complete representation individually tailored to each client’s needs, from counseling her clients on non-litigation matters and attempting to resolve disputes early on, to providing vigorous representation throughout the litigation process and at trial. Mary’s experience as an ardent corporate advisor and skilled litigator allows her to serve as outside general counsel to many clients.

Mary’s focus in commercial litigation ranges from complex multi-party business litigation to simple contract disputes. Mary has extensive experience in lender liability, business torts, contract enforcement claims, contract defense claims, and real estate related disputes. She has been successful in numerous trials where she obtained beneficial outcomes for her clients.

Complimenting her commercial litigation experience, Mary’s practice also includes trust and probate litigation, as well as corporate and real-estate transaction matters. This multi-faceted approach enables Mary to provide a full-service representation to her clients.
