Cathy Jean (Powers) Strombom died the 1st of December, 2018 in Seattle, WA. Cathy was born in Bremerton, WA, November 4th, 1949, to Paul Powers Jr and Carolyn Powers. She grew up in Port Orchard, WA with her sister Deidra. Cathy went to Whitman College and majored in mathematics. She met her soon-to-be husband David Strombom while at Whitman, and they were married June 17th, 1972. After graduate school in city planning and transportation at Harvard and University of Washington, Cathy and David had multiple work and travel assignments overseas including Morocco, Iran, India, Turkey and Pakistan. Beach time every year was in Mazatlan, Mexico, always with a big group from her family.

Cathy worked 34 years with the Seattle office of Parsons Brinckerhoff (recently incorporated into WSP), where she was a Vice President and headed the planning team that did much of the early work on major transportation structures and systems on the West coast and in Hawaii. Cathy was highly involved in two leadership development groups in Seattle, Women's Transportation Seminar (WTS) and Leadership Tomorrow for training young professionals.

Cathy had multiple great friends all of her life. She is survived by her husband David, her son Paul (Elizabeth), her mother Carolyn Powers, and sister Deidra (Tag) Larson, as well as by an extended family of loving and supportive relatives and lifelong friends across the country and around the world.

She died in capable hands at Swedish Hospital, having run the course of treatments for multiple myeloma over the past two and a half years. A memorial service will be held January 12th at 2:00pm at Lakeside School Wright Community Center. She died very peacefully, surrounded by family, loving this life.

I remember Cathy's graciousness when I joined Parsons Brinckerhoff (back in the day when it was Parsons Brinckerhoff Quade & Douglas, Inc.). I always admired her quiet determination to help staff be the best they can be, and how dedicated she was to her transportation team, making sure they had all the tools they needed in order to be successful at their job. She was a true leader and a great role model at work. There were times I called on her for advice (she was an unofficial mentor of mine), and she was always willing to listen and offer suggestions and ask questions to help me move forward.

So sad to see her go.

Cathy was a friend and colleague for the past 30 years. I can't think of a more genuine and honest person in all of my working years. Although we did not see each other much these last years, she was always there with a smile and hug when we did get together. A truly wonderful person to know in my life. I will miss her.

There are many of us today that have Cathy to thank for the career paths we are on. Her wisdom and compassion for all of us will be so sorely missed. I will miss my annual treks to the northwest and our lunch or coffee catch up sessions on the latest in our work and with our families. She was always present and willing to lend an ear - and a helpful suggestion or two along the way.

David and Paul - while I can't even imagine the loss you must feel, just know we all are mourning with you. Cathy will always be with us!

Cathy- since we first met (you at PSCOG) (I in Kitsap County) you have been a change maker in my life and in so many others. There was work, travel, celebrations, commiserations, and so many other moments and times of courage that made my life richer. You are missed but in my grateful heart.

Cathy - you were a wonderful mentor and treasured friend to me the past 12 years. There is a void that can never be filled. I will treasure the memories of our evenings at the 5th Ave Theatre and dancing with the cast of Mama Mia! You will be in my heart forever.
