"A safe space to explore, heal, and grow."
Mindful meditation practice

As a psychotherapist, I cultivate a safe & supportive atmosphere in which my clients explore thoughts and feelings about the important areas in their lives that may be broken, or not working as well as one hoped and planned. Adults often address major life changes, symptoms of anxiety and depression, relationship issues, as well as struggles with substance misuse and alcoholism. Adolescents and families often work well together in treatment facing family issues in a safe, and structured therapeutic environment. Students struggling with learning difficulties and associated deficits in self esteem are an area of specialty. In general, I am devoted to helping people, from a wide range of backgrounds, to clarify their understanding of their lives, reduce unnecessary suffering, and strengthen close interpersonal relationships. .

A Walking Meditation: Finding Calm in Nature’s Beauty

I’m Dr. Glenn Horwitz, a clinical psychologist and psychotherapist. In my work, I am interested not only in understanding emotional suffering, but also in helping people discover practical, experiential ways to feel more grounded and connected. One approach I have found personally meaningful is walking meditation in nature. Rather than trying to make the mind become calm, we gently shift our attention toward what is already around us—the sounds of the landscape, changing light, the movement of water, and the physical experience of walking.
