As an attorney at BrownWinick law firm, I work primarily in the intellectual property practice group. Growing up I was always involved in the arts and sciences, and as those interests evolved, they led me to become an advocate for artists and scientists. Witnessing my clients' unique ideas is one of the best parts of my job. I love coming to work every day knowing that I get to play a small part in protecting those ideas.

My Approach

Seeing my clients' creativity inspires me to pursue similarly creative and effective legal solutions to cater to their specific needs. It is my goal as your attorney to present you with straightforward legal strategies and solutions even in the most complex of situations. Whether it's applying for a patent, policing a copyrighted work, or defending a trademark, I'm always available to help you work through any legal issues you may run into, so you can continue zealously pursuing your passions.

More About Me

In 2016, I graduated from Iowa State University with a B.S. in chemical engineering. I went on to graduate from Drake University Law School in 2019 and was admitted to the Iowa bar the same year. Prior to joining BrownWinick, I was admitted to the Illinois bar and practiced at an intellectual property boutique firm outside of Chicago.

I am a member of the American Institute of Chemical Engineers and a member of their Chemical Engineering and the Law forum.
