About The Firm

Groff Murphy PLLC was founded in 1992 by lawyers with big firm experience who wanted to provide high-quality legal services to their clients with the flexibility and efficiency of a focused smaller firm.  Since that date, Groff Murphy has attracted experienced lawyers with similar goals and commitments.  We are a team of highly capable lawyers who enjoy practicing together and being an integral part of our clients’ business team.
