Eric Peterson

MA, LPCC, LADC

Eric is a Licensed Professional Clinical Counselor and Licensed Alcohol and Drug Counselor with extensive training in psychedelic integration and ketamine-assisted therapy. He focuses on treating addictions, anxiety, depression, trauma, and helping with sports performance issues. He believes that developing a safe and secure relationship with each of his patients is essential for them to learn new ways of thinking and behaving, to find meaning and purpose in their life, and to move towards creating a whole and complete sense of self. Eric’s approach to personal change is informed by acceptance and commitment therapy, cognitive-behavioral therapy, transpersonal psychology, person-centered therapy, & somatic approaches to healing.

Using primarily Acceptance and Commitment Therapy (ACT), along with other techniques, you will learn to increase your awareness and attention to patterns of thinking and behaving that are keeping you stuck in life. By developing helpful skills to change the way you respond to difficult thoughts and feelings, you can learn to have a more relaxed, creative, and flexible mind & body.

Eric also enjoy helping athletes with their mental health and developing mental performance skills to help them succeed. You can learn pragmatic skills to consciously activate the “flow state” and learn how to control your attention for peak performance. We also can focus on learning how to manage difficult thoughts and feelings that may be holding you back. If you are an athlete and want help with the mental side of your sport, please reach out to learn more on how you can develop psychological skills to improve your performance. 

Eric also helps fathers who struggle with mental health and have difficulties being present with their families. Life and work can be stressful, and our minds will constantly be holding on to these thoughts and ambitions. When we aren’t giving our loved ones our full attention and energy, we aren’t being fully present for them. Learning to develop useful mindfulness and relaxation skills, while connecting your behaviors with core values, can be an effective way to show up for your family that feels right to you. 

In addition to the above services, Eric also offers consultation and training for ketamine assisted psychotherapy. If you are needing help or wanting to get trained in this area of work, please reach out to discuss. When Eric is not in his therapist role, teaching, or giving presentations, you can find him running ultramarathons, downhill/cross country skiing, rollerblading, or taking his dog, Harley, for a walk.

MA, LPCC, SEP

Shireen is an Integrative Therapist and Somatic Experiencing Practitioner who blends mind, body, and soul into her practice. As a Persian-American, mixed-heritage and multi-religious/spiritual human, she is dedicated to using a non-pathologizing, dichotomous and nuanced lens when working with fellow humans from all walks of life. Her training includes psychedelic-assisted psychotherapy, Brainspotting, Somatic Experiencing, Embodied Movement, Ecotherapy, Energy Healing, Parts Work, and Creative Expression.  Shireen supports clients in exploring their experiences with trauma, eating disorders, depression, anxiety, ADHD, identity, and ancestral connections while fostering balance and integration.

In addition, she has training in energy healing, personal training, yoga, and meditation coaching.

Shireen’s passion for holding the unconditional and supportive space in the way she does stems from the ups and downs in her own healing journey, and the magic that comes from unearthing our authentic and embodied inner healing wisdom.

Dr. Shawn Olson

MD, MPH, DipABLM, FAIHM

Dr. Shawn Olson is a board certified occupational and lifestyle medicine physician, fellowship trained in integrative medicine and completing a fellowship in integrative psychiatry. He brings more than a decade of experience across integrative and psychedelic medicine, anesthesiology, spine care, chronic pain management, and public health. With advanced training in ketamine and psychedelic therapies, he practices whole person, preventive care that blends rigorous science with enduring healing traditions to help patients build presence, resilience, and lasting well-being.

This insight led him to create RealCare and the Dome Ranch Lifestyle Medicine Collaborative, where science and soul meet in a supportive environment designed to foster presence and lasting well-being.
