Matthew Kaminski

Managing Partner

Born and raised in South Florida, Matthew Kaminski received a degree in History from the University of Florida in 2006. He later earned a Juris Doctorate degree from Florida A&M College of Law in 2009.

Matthew Kaminski has been practicing law since passing the Florida Bar in 2009. He began working at a real estate litigation firm in Plantation, Florida. Mr. Kaminski participated in mediations and civil court practice (including judicial mortgage foreclosure, title actions, and evictions) all over the State of Florida. 

In 2011, Mr. Kaminski moved to Seattle and went on to open his own office in the heart of Belltown at the historic Markham Building on 3rd Ave and Blanchard. In addition to providing quality and affordable legal services through his practice, he has chosen to give back to his new home by volunteering with…

the King County Bar association’s Housing Justice Project and Kinship Care Solutions Project providing free services to Low-Income clients. Matthew Kaminski also proudly works with the Legal Voice, a women’s rights group benefiting the State of Washington. He is currently the vice president of the Yakima Volunteer Attorney Services Board.

“I’ve always felt that an attorney is measured by what he gives back to the community.”

When Mr. Ashby invited him from Seattle to introduce him to his Family Law firm approach, one that merged a caring, client-centric approach with 21st century technology, Matt knew that this firm was ushering him in a new approach to family law and that he wanted to be a part of the Ashby firm “family.” The firm and he share the core belief that no one wins when two parents are pitted against each other, instead he has always striven to find collaborative solutions to difficult problems.

This collaboration continued until 3/25/2019, when Ashby Law withdrew from the Yakima / Kittitas area. Matthew Kaminski and Brooke Barnes decided to create their own firm to not only focus carrying out the dream of bringing a different approach to family law issues. Yakima Law, PLLC was born out of their desire to help more people, including criminal law and other civil matters.

Jodi Mumford

Attorney

Jodi (Felton) Mumford was born and raised in Yakima. She is a graduated of Eisenhower High School, Washington State University, and the University of Idaho College of Law. Jodi has practiced law in Yakima since 2009, focusing mainly on immigration law.

Jodi likes the personal aspect of immigration law very much. Meeting new people every day with different backgrounds and experiences and being able to help them navigate the confusing and ever-changing immigration laws whether it be in immigration court when facing deportation or helping her clients to obtain citizenship, legal residence, or permission to work in the United States. Seeing a client obtain their first legal resident card, take the oath to become a United States citizen, or simply witnessing a hug between spouses or a parent and child who no longer have to worry about losing a family member to deportation are the best parts of her job.

Outside the office Jodi enjoys spending time with her husband and two young daughters. Jodi loves to spend time outdoors especially in the summer and can often be found boating on Lake Roosevelt. Some of her other interests include reading, working out, attending sporting events, and enjoying many of the local wineries and breweries the Yakima Valley has to offer.
