Electrical Engineer

Meet supervisor and electrical engineer Teresa Castillón, based in our Fort Worth office. Teresa has been with Freese and Nichols for 18 years, and not only has she progressed in her career within the same office and group she started as an intern, but she has also been able to merge her passion for serving the community with her job at Freese and Nichols by leading the effort for the MEP group to adopt families from the Women’s Center every Christmas for the past 11 years.

What drew you to engineering?

In school, I always loved math and science, and growing up with a brother and cousins who were engineers helped pave the trajectory toward the engineering industry. They inspired me to use my love for math and science to serve and help communities

Tell us about your internship at Freese and Nichols.

I started my internship in 2004 with the electrical group in Fort Worth. I did CAD work and helped with lighting designs and building one-line diagrams. What’s really cool about the internship program is that I have made lifelong friends who grew with me in my career. Dan Koss and Misty Thomison were both interns with me. Dan is now a discipline senior advisor in our electrical group, and Misty is now the group manager in the structural group.



What kind of projects do you typically work on?

I mainly work on renovation projects, and I am currently a project manager for several projects for the Texas Military Department, which is one of our main clients. I also supervise a group of Engineers in Training (EIT) and designers in the electrical group.

What about Freese and Nichols made you stay over the long term?

I developed good relationships with the electrical team as well as other people in the facilities group. They were excellent in coaching me and very patient. They have become family and have been very supportive throughout all my years here, both on a professional and personal level. The flexibility I am offered has allowed me to thrive as a professional engineer and as a mom of two beautiful girls. Even as an intern, I felt as though I was already a part of the FNI family.

What is something people would be surprised to know about you?

I absolutely love to dance! I like to listen to audible books, and I am the photographer at my church. I’m an absolute nerd about spelling, grammar and personal development.
