Our Philosophy

“The main business of a lawyer is to take the romance, the mystery, the irony, the ambiguity out of everything he touches.”

-Antonin Scalia

At the end of the day, our primary goal at the Law Office of Erin Melsheimer, PLLC is to make sure each of our clients walks out the door understanding their situation, their options, and how to evaluate which solution is best for them. As skilled as we are at advocacy, we have never had a client that was happy with an outcome they didn’t understand.

Erin Melsheimer, Attorney

Erin Melsheimer is the owner and founder of Law Office of Erin Melsheimer, PLLC . Her practice focuses mainly on highly contentious family law matters and criminal defense work. She is extremely comfortable in a courtroom, but understands all cases are different. She strives to provide each client with a strategy that fits their unique goals. She is also certified in collaborative law.

Erin is a native Texan; she says “y’all” and “fixin’ to” and “hook’em.” She received her B.A. in American Studies from the University of Texas in Austin and her J.D. from Southern Methodist University’s Dedman School of Law. She began her career as a prosecutor in McLennan County, Texas (home of Chip and Joanna Gaines!) where she prosecuted all levels of state crimes. In 2011, she started her own practice, Law Office of Erin Melsheimer, PLLC, doing a combination of criminal defense, family law, and child protective services work as both an ad litem for parents and children. She also served as an Associate Judge of Collin County Probate Court #1 from 2017-2019 handling a variety of mental health matters. Erin became licensed in Montana in 2019, just before relocating here.

When Erin is not in the office, you can find her spending time with her husband, her son, and their French bulldog. She loves a margarita on a patio, a float down the Madison, exploring the mountains, and visiting friends and family in Texas often.

Collaborative law is a unique dispute resolution technique used in family law matters that shifts the focus from winning to finding solutions. As a result, parties are better able to preserve co-parenting relationships, able to think outside of the box to develop solutions that are specific to their individual circumstances, and avoid the blood pressure spikes that come with traditional litigation. Each case has four professionals involved: two attorneys trained in collaborative law (one for each party), a mental health neutral, and a financial neutral.

Nothing can rock your world as much as these three words, “You’re under arrest.” With experience as both prosecutors and defense attorneys, we are prepared to assist you with whatever trouble you find yourself in- from DUIs, to thefts, to assaults, to murder.
