Lisa Marquis
Practice Description
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. Even
in cases that need to be handled through the more traditional litigation process, Lisa strives
to be part of the solution and not part of the problem.
Representative Experience
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. After 15 years in practice with Sharon, Lisa joined with Hastings Hanshaw and
Collin Kennedy in 2012 to start a family law practice with the firm of Hanshaw Kennedy
Marquis. In April of 2015, Lisa joined the firm of Quilling, Selander, Lownds, Winslett &
Moser, P.C. to head up their Collin County office, which opened in Plano on April 1, 2015.
Lisa is well known for her work in collaborative law, successfully handling more than 130
cases. She has been secretary, vice-president and president of the Collin County Bar
Association, chair of the Collin County Bench/Bar Foundation, and speaker and course
director for the State Bar of Texas Collaborative Law Conference. She is an active member
of the Association of Networking Professionals, in which she has held the positions of
Vice-President and President for multiple terms. Lisa has also served as a Girl Scout Leader
in Celina and on the church council of Rejoice Lutheran Church in Frisco.
