Donna Jewett

Truest Founder/Attorney

Direct, genuine, highly-informed and compassionate – these are the qualities that have enabled her to gain the trust of her clients since 1994. Whether she’s providing trust reviews, family wealth planning or creating a new estate and trust, Donna is passionate about protecting the families she serves and ensuring her client’s best interests are always at the forefront.

Prior to opening the Law Office of Donna Farar Jewett, PLLC, Donna graduated cum laude in 1990 with a Juris Doctorate from Willamette University College of Law after earning her Bachelor of Arts degree in Economics from the University of Colorado. She then gained direct legal experience as a Judicial Clerk in the Federal District Court for the District of Arizona. Afterwards, she worked at two Arizona firms where she focused on Criminal Law, Medical Malpractice and Family Law. She is a former pro tem.

Donna’s private practice had focused on Family Law and Mediation for over 25 years and evolved into Truest Law, a professional trust and estate planning practice. In addition to her years of experience, Donna relies on an established resource network to provide her clients with the added support for all their needs.

When Donna is not helping her clients, she can be found out on the Arizona trails hiking and biking. She is active in her church and the Metro-Phoenix community.
