EXPERIENCE

Lisa Marquis believes in settling family cases collaboratively whenever possible. Her clients view the collaborative process as a way to better control the outcome of their case and reduce stress and trauma to their family. Divorce is certainly an ending, but Lisa also sees it as the beginning of a new family unit. She believes that the collaborative process can smooth the transition for you and your children. Lisa also understands that some cases cannot be handled collaboratively and also effectively represents clients in contested matters that are presented to the court for determination. However, even in those contested cases, Lisa uses her training as a collaborative attorney to minimize the level of conflict between the parties and endeavors to always put the best interest of the children first.

In 1991 Lisa began her legal career as a litigation attorney with Streich Lang in Phoenix. In 1994 she moved back to her home state of Texas to work as a tax attorney with the Dallas law firm of Johnson & Gibbs. When Johnson & Gibbs disbanded in 1995, Lisa began practicing family law in Plano. In 1997, Lisa partnered with Sharon Easley to form Easley & Marquis. In 2012, Easley & Marquis dissolved and Lisa joined with Hastings Hanshaw and Collin Kennedy to create and lead the family law section at Hanshaw Kennedy Marquis, PLLC.

Lisa is well known for her work in collaborative law, successfully handling more than 100 cases. She has been secretary, vice-president and president of the Collin County Bar Association, chair of the Collin County Bench/Bar Foundation and vice-president of the Plano chapter of the American Business Women’s Association.

Lisa grew up in Devine, Texas. In 1988 she graduated from the University of Texas at Austin with a double major in Government and Sociology, and in 1991 received her Juris Doctorate, with honors, from the University of Texas School of Law. Lisa and her husband of 25 years, Steve Harklau, live in Celina and have two daughters. Lisa is a Girl Scout Leader in Celina and previously served on the church council of Rejoice Lutheran Church in Frisco.
