Alex Ybarra, L.G.
Senior Staff Geologist

Department: Geotechnical Engineering

AESI Staff since 2016

Alex started his journey at AESI back in April of 2016 and quickly jumped into the world of construction monitoring and geotechnical observation. While in school, Alex knew he didn’t want a typical desk job, and instead wanted to spend time outdoors and doing something where his work let him explore the different communities around him. After taking his first geology class, he never looked back and received a degree in Geology from Western Washington University.​

Alex is an essential part of the AESI team. He is the full-time on-site geologist for many of our south end projects including large scale land development projects in and around the City of Black Diamond. Alex’s strong people skills and charismatic personality allow him to create meaningful connections with contractors and clients and ensure projects run smoothly. Alex enjoys revisiting old sites to see the completed product and finds it rewarding to know he played a part in the project’s success and helped set a good foundation for the rest of the project. In the future, Alex hopes to continue growing his skills and making connections with the project teams.​

Alex has a busy summer ahead of him as he prepares to welcome the birth of his baby girl in July (Congratulations!) and embraces the rewards and challenges that come with being a new dad. Until then, he hopes to fill his summer with plenty of fishing and golfing and daydreaming about the first day of snowboarding season.


Katie Promoted to Project Water Resource Scientist!

Katie joined AESI five years ago as admin support and technical editing in our Mount Vernon office. Over the past three years, she has been an integral part of the Hydro group and a key member of our water rights team. Through her dedication and hard work, Katie has become an expert in water rights and now serves as the primary point of contact and project manager for 20 different water rights projects, including some of our largest irrigation water rights clients as they face the impending adjudication in the Nooksack Basin. Given the challenging and uncertain future that these clients face, they look to Katie to provide sound strategies to manage their water rights and prepare for an adjudication that may take 30 years or more to complete. Recently, Katie has successfully developed one of Skagit County's largest irrigators as a new AESI client. Additionally, her dedication to the topic and natural leadership have made Katie the go-to person for all things water rights related.

In addition to her water rights work, Katie manages many of our north-end quarterly, bi-annual, and annual water resources monitoring projects.

Congratulations, Katie, on your well deserved promotion!
