Kate E. Sereff

Broomfield, Colorado

I have known I wanted to be a lawyer since high school, when I participated in my first mock trial program.  After graduating from the University of Nebraska-Lincoln, I moved to Virginia to begin law school at Washington and Lee University.  I graduated law school in May 2011 and moved to Colorado with my family.  I passed the bar in Colorado and was admitted to practice in 2011.  I have worked primarily in family law since 2011, including working as a solo practioner from 2014 through 2016.  I began as an associate with Cooper, Tanis & Armas, P.C., in February 2017.

I am drawn to practice primarly in family law as this area of law provides opportunities to work directly with clients, educate and inform clients about the legal process and their rights, and assist clients through a difficult transition.  I advocate for my clients to obtain the best result possible for their particular case, whether through direct settlement, mediation, or litigation, to help clients move forward after their case is concluded.  I understand that each person and each case is different and work with clients to provide individual strategy and options.
