Attorneys and Staff

Who we are

Shantelle L. Argyle, Attorney at Law
Co-Founder and Executive Director

Shantelle Argyle finished law school with the intention of helping people like herself; people of modest means and without a lot of options for legal representation. Shantelle is passionate about serving those who really have no other options: those in the middle, who are working hard but can be easily crippled by a legal setback. When no such job existed, Shantelle started Open Legal Services, Utah’s first and only nonprofit modest means law firm, with Daniel Spencer in the hopes of serving that group and also building a life for herself and her family. So far, it’s working! It’s sustainable, growing rapidly, and helping so many people. Plus, it’s shaking things up and that is something Shantelle always tries to do.

Shantelle has worked for several private law firms and as a public defender. She co-founded Open Legal Services to bring truly affordable justice to those who really have no other options. She practices criminal and family law, and has worked on cases ranging from child custody to murder. She is passionate about the OLS mission, and will tell anyone she can about the Revolution in Affordable Legal Services. Shantelle attended law school at the University of Utah and graduated in 2013. She is admitted to practice law in Utah. Avvo - Rate your Lawyer. Get Free Legal Advice.
