Ookham is a first generation American and Tri-Cities resident who graduated from Pasco High School. He joined the military directly after high school, where he spent the next four years on active duty as a paratrooper with the Army’s 82nd Airborne Division based in Fort Bragg, North Carolina. From there, Ookham transitioned into the Army Reserves, where he still currently serves. He is now happily married with two children and loves checking out locally-owned restaurants and eateries around town in his spare time.

Ookham’s favorite part of the real estate business is establishing relationships with his clients. His time in the military has taught him the importance of work ethic and has shaped him into the real estate agent he is today. He strives to make interactions feel less transactional and more personal. Ookham understands that buying or selling a home is a huge investment, both emotionally and financially. His main priority is to help you through the real estate process with clear, timely communication and outstanding customer service!

I have known Ookham for a long time as a friend and now as a client. Ookham went above and beyond to make sure our desires were of the upmost importance from our desires of a home and the conflicts that arose with a new build. He is decisive and prompt in getting resolution on all things. The network he provides from Loan Officers and Inspections referrals is top notch and they care as much as he does. I would highly recommend Ookham!

My husband and I were connected with Ookham via our lender (who we connected with over Zillow!). The four of us met together and it was clear that he had our best interest in mind. Any questions we had as first time homebuyers, he was there to answer and very timely. If I saw a listing that we were interested in, Ookham would schedule a showing immediately. He offered sound advice and didn’t pressure us into making a decision. He helped us find our perfect home and we are so thankful for his time, patience and knowledge!
