Paul O'Brien


As an early teen Paul separated from the Episcopal Church since the teachings did not adequately explain life's reality for him. In general, he neither debates nor argues about religion since his beliefs are firm as a Humanist with no hostility towards people of faith. What guides his belief system is a strong belief and defense of science and the scientific method which took him down the path of earning a Ph.D. degree in sociology from Colorado State University in Fort Collins. Since his retirement from the professoriate, he has been active in the Denver secular community by not only being a member of the Secular Hub but also currently serving as the treasurer. His dream for the future is to have an open, caring and safe permanent location along the Front Range for all Humanists, agnostics, atheists and non-believers. A location also available for sharing with other Front Range secular communities.

Dirk Huizenga


I have been a non-religious person most of my life, but have very seldom have been in the company of atheists more than one other at a time. About seven years ago, I started getting involved with secular groups in Colorado. I think the secular community needs more of a voice in our society and I want to help that happen. Also the separation of church and state needs to be protected. I want to be more involved and help the Secular Hub community expand.

I enjoy putting my IT experience to work helping the Secular Hub to grow and connect with our community. As a humanist, I want to help create a more humane society through an ethic based on human and other natural values in the spirit of reason and free inquiry, separate from supernatural views of reality.

Heili D. Lehr


When I found the Secular Hub in 2014, I had recently gone through a divorce and was seeking community. As someone who grew up in a family of Secular Humanists, I was overjoyed to find such a large, vibrant group of like-minded people to call my friends. Over the years I have been involved with the Secular Singles group, the Secular Adventure Crew, the Events Committee bringing in national speakers and planning fun social events, the Relocation committee assisting with finding the Hub’s new home, and as a co-facilitator of the Death Café discussion group. I am a Mental Health Counselor in private practice who specializes in Loss, Change, Grief, Religious Trauma and Life Transitions and am listed on Recovering From Religion’s Secular Therapy Project directory. I have a deep and enduring passion for supporting the secular community in a wide variety of ways, and as a board member I am committed to the vision of a thriving, dynamic, inclusive and fun secular community center we can all call home for many years to come. and help the Hub continue to grow and reach out to our community.
