Matthew Grimshaw began Grimshaw Law PLLC in 2018. Prior to that, he served as an attorney for the Cramp Law Firm. His association with the Cramp Law Firm began as a law clerk and then he joined the firm as an Attorney in November of 2016. He received his law degree in 2016 from St. Mary's University School of Law and his MBA in 2015 from St. Mary's University Greehey School of Business. Matthew is a member of the Legal Honors Society Phi Delta Phi and graduated from St. Mary's University School of Law in the top 18% of his class.

Although his family's roots have always been in Texas, Matthew grew up in a military family in San Diego, California. He moved to San Antonio in 2008 to attend Trinity University where he played two years of varsity baseball. After two years, he transferred to Texas A&M University where he earned his Bachelor of Arts degree in History and Economics. His experience as a child in a military family taught him the importance of caring for and protecting the unique needs of individual families as well as the strength of families in serving and securing the needs of the larger community at the local, state, and national levels. His passion is to bring his expertise in family and business law together to be your best advocate in navigating the legal process, allowing you more time to focus on your family. Matthew provides straight-forward, compassionate, consistent counsel in your time of family need whether it involves resolving a divorce, determining custody and child support issues, adoption, planning an estate, managing the probate process, or other family related legal needs.

When he is not working, Matthew spends time with his wife and two children. He loves to keep up with the latest in sports, especially the Spurs, and San Diego Chargers and Texas A&M Aggies, as well as the Cowboys, Texans, and Astros. Matthew loves exploring new restaurants, parks, and museums, and enjoying all the family fun San Antonio has to offer.
