In early 2020 I decided to switch my career path to be able to work closer to home. I’m a beginner in this field and I'm happy to learn something new every day. My goal was to acquire a new set of skills and expand my professional experience. Growing up in Washington State has been nothing short of amazing. I’m a wife, mother, and have life-long friends here.

I’ve worked in the construction field for over 25 years. Aside from estimating, I’ve been a supervisor, project manager, and have worked in the field. I’ve worked on many projects though out the years. It takes a team to build, and I’m glad to be part of a good one. I’ve been a lifelong resident of Washington State, went to the University of Washington and hold a BA in International Trade and Development from the Jackson School.
