About me

I was born and raised in the desert of Southern California, but got tired of the heat and decided to move to the Pacific Northwest in 2011. I graduated from the University of La Verne College of Law in 2010 where I had the opportunity to work in the California Courts gaining valuable experience helping clients with family law cases. Since passing the bar, I have had the opportunity to assist clients in a wide variety of law which has given me valuable experience.  I am well known among friends and family as an avid Batman fan and general lover of science fiction.
