Katelyn has been practicing law for more than twenty years. She has a traditional labor law practice and represents labor unions before arbitrators, state labor boards, and the National Labor Relations Board. She also negotiates labor contracts and advises clients on strategy and changes in the law that may affect their rights or obligations.


Katelyn also brings a depth of experience to advising clients on issues concerning disabled employees, fitness for duty tests, medical leave, and other employment-related issues. She provides advice and guidance to labor union entities regarding their obligations under the law to their employees, members, apprentices, and other stakeholders. She has been reviewing and advising on the intersection of disability, worker injury, and family medical leave issues since she began practicing law. Katelyn has assisted dozens of clients with disabilities in achieving reasonable accommodations in the workplace. 


She represents clients in the state and federal courts in Oregon, Washington, and Alaska, and works on appeals. She defends her labor union clients in court and in administrative actions when the need arises. Katelyn has acted as local counsel for national labor unions.

In addition to her labor practice, Katelyn represents individuals before professional licensing boards and commissions. She looks for creative opportunities and solutions but will litigate a case when necessary to protect her client's professional reputation and livelihood. She has represented clients before the Department of Public Safety Standards Training, Oregon Medical Board, Oregon Board of Nursing, Teachers Standards and Practices Commission, Oregon Health Authority, Oregon Board of Dentistry, Oregon Board of Licensed Counselors and Therapists, Oregon Government Ethics Commission, the Medical Quality Assurance Commission (in Washington), the Alaska Board of Nursing, and other agencies. Katelyn has experience working with professionals who are seeking help for alcohol and substance abuse problems, or for mental health concerns.


Katelyn represents select clients in employment-related matters and civil rights claims. She has litigated claims under Section 1983 (constitutional claims), Title VII, the ADA, the ADEA, as well as state law claims and contract disputes, in state and federal courts, before arbitrators and in administrative hearings. She represents federal employees and contractors in administrative proceedings related to employment discipline and whistleblower status.

Katelyn was previously an equity partner at the Tedesco Law Group. She started her career as an associate attorney at the Law Offices of Judy Snyder. Before becoming a lawyer, Katelyn worked in many industries including as a seasonal forest fire fighter, a claims adjuster for a military shipping company, a library employee working in the "stacks," various roles in non-profit organizations devoted to serving children and families, and for a vegan food company. Having worked with people from different backgrounds and industries allows her to find common ground with clients from all walks of life.


When not fighting for workers’ rights, Katelyn enjoys spending time with her family, running with her dog, traveling, camping, and reading.
