What clients have to say about Jeff:

"I had a very hard time with past lawyers before seeing Jeff who came well recommended. The case we worked on together was very emotional for me. He helped me bring back balance in my life through a very difficult time. 

He supported me always with a great attitude, smile and a great spirit. He also set the appropriate expectations up front and worked through it with me what was best within the parameters of King County and Washington state law. He also mentored me on the overall picture and what was best to keep the entire family healthy and myself long term. 

I am very analytical and read many books on the subject of our case as well as research online. His advice was always correct and he helped to further educate me as well around what I read.

More About Jeff

Jeff Gregory is a lifelong Washingtonian. He graduated from Kelso High School in 1992 and then attended Lower Columbia College where he played collegiate baseball. From there he finished his undergraduate degree in Psychology at the University of Washington in 1997. He then attended Gonzaga Law School where he was associate editor of the Law Review and graduated with his Juris Doctorate with Honors in 2000.

While in law school he worked as a Rule 9 with the King County Prosecuting Attorney’s office and then accepted the position upon graduation as a full Deputy Prosecuting Attorney. He practiced as a Deputy Prosecutor with King County at the District and Superior Court Levels for 9 years and was named a Senior Deputy Prosecuting Attorney in 2007.

After years of the public practice he decided to open his own firm and in 2010 opened the doors of Gregory & Rooney PLLC in the Bellevue area. The Firm’s areas of practice included private criminal defense and family law. After five years of developing and running a successful practice the desire to return to full time criminal law began to take hold and so in 2014 he accepted a position with Stewart MacNichols and Harmell, one of the premier criminal defense firms in the Puget Sound Area.

His fulltime criminal practiceis now limited to criminal defense work. Due to the wide range of experience throughout his career, Jeff is able to practice confidently in many different courts in the Northwest including most municipalities, all district courts as well as Superior Court. His time as both a Deputy Prosecuting Attorney and private and Public Defense counsel for many years give Jeff an unmatched ability to know both sides of every case and to move knowledgeably and deftly through any of our courts you mind find yourself in.
