Diane Castens

After returning to Colorado in 2013, my husband and I settled in the Brighton area, where we have enjoyed being active members of the community. I began working at Pennock Center in November 2014 as a part-time administrative assistant and was promoted to Office Manager in July 2025.

I completed a two-year Office Education program at the Career Development Center during high school, earning a certificate in Office Management. With more than 40 years of experience in office administration and management, I bring both expertise and creativity to my role at Pennock Center. I enjoy designing table presentations for vendor fairs, creating engaging bulletin board displays, and contributing my talents to the execution of our annual Healing Hearts fundraiser.

Passionate about helping children, I serve on the board of directors for a nonprofit foundation that supports the needs of children living in children’s homes. I also volunteer with other nonprofit organizations whenever help is needed. As a Colorado native, I love spending time in the mountains camping, fishing, and hiking. I also enjoy crocheting, reading a good book, and—most of all—being a “Grammie,” one of my greatest joys.
