Dave Taylor, MA, ALMFT
Dave received his master’s degree in Marriage and Family Therapy from Wheaton College in the spring of 2019. During his graduate school internship, Dave provided therapy to couples, adults, adolescents, and families from a variety of backgrounds at Cedar Tree Counseling in St. Charles. There he worked with a number of issues, including marital and family conflict, depression, anxiety, addiction, anger, various types of trauma, life transitions, and infidelity. In particular, Dave worked extensively with individuals and couples impacted by sex and video game addiction and young people experiencing challenges in their post-college transition to independence. Dave also led clients affected by anxiety in mindfulness meditation sessions and co-led a support group for men struggling with anxiety, depression, and anger. During his time at Cedar Tree, Dave discovered a special joy in working with couples, as so much of a person’s identity and worth stems from the definition discovered within intimate relationships.
Prior to pursuing a career as a therapist, Dave has held a variety of jobs, including registrar at a doctoral program for clinical social workers, computer support technician, Starbucks barista, kids’ musician, substitute teacher, and even wedding deejay. Over the past 20 years, Dave has performed improvised comedy, which has only fueled his desire to become a therapist. In the cardinal rule of improv, “yes and…”—saying yes to another person’s initiations and then building on them with your ideas—Dave has seen a correlation to the therapeutic process: “yes and…” allows for an immediate and deep connection between people that can facilitate change. In recent years, Dave was a stay-at-home dad to his three kids while his wife served as the breadwinner. Taking care of the physical, emotional, intellectual, and spiritual needs of three small children while trying to remain relevant—creatively and professionally—has been one of the more difficult experiences of Dave’s life. This challenge has given him a special heart for parents who feel overwhelmed and out-of-touch with who they are or who they want to be.
