Just a few years ago, I was caught up in a cycle of self-doubt, shame, and failure. I was early on in adulthood, and already I felt completely worn out; I was convinced my life would end in ruins. Eventually, I was able to seek counseling, and this became a significant factor in helping me find a new sense of hope and freedom. I became a counselor out of a desire to share this gift with others. I aim to create a safe space where my clients can discover new hope on their journey. When you walk into my office, I want you to know that you are welcome here; you belong, and you matter.

Do you struggle with persistent anxiety or depression? Do you have an adolescent with emotional or behavioral problems? Are you having issues with addiction? I've been assisting people in the Denver area for the past thirty years. I have worked in inpatient psychiatry and drug and alcohol rehabilitation, and I currently teach psychology and related subjects at the University of Denver. Although my clinical specialties are working with adolescents and addictive issues, I also work with individuals, couples, and families dealing with mood disorders, anger management, men's issues, and spiritual issues.

"I believe that clinical credentials are only part of the process of selecting a therapist. To that end, I offer a free fifteen-minute consultation to determine if I'm the right therapist for you."

I am currently accepting new clients. I’m so glad you’re here. Taking the step to reach out is often the hardest part, so congratulations on being here. I especially love supporting women navigating anxiety, depression, big life changes, postpartum, and the ups and downs of motherhood.
