About me

Advocate. Counselor. Attorney. I work with residents in Colorado and many nearby communities on legal matters that are critical to their family.


After law school, I spent years working with respected legal professionals on various family law and estate planning matters, honing my skills and learning how to best serve our local community. In 2014 I decided to put my experience to work more directly and opened The Cossitt Law Firm. We provide comprehensive and advocacy with family law and estate planning matters.


Are you going through a divorce? Trying to settle child custody disputes? Going through a child support battle? Wondering about creating a trust or drafting a will?


My firm can help with all of this and more. I pride myself on providing tailored guidance that takes your specific goals into account. From managing fair settlements to aggressive advocacy in the courtroom, I am willing to do whatever necessary to protect your rights.
