Therapy in California With Teva Johnstone

Practice Owner & Psychotherapist

I have extensive training, supervision, and consultation in Exposure and Response Prevention (ERP), which is a highly effective Cognitive-Behavioral Therapy for Obsessive Compulsive Disorder. I practice Rumination-Focused ERP, an integrative therapy that allows for acute symptom relief while addressing emotional and interpersonal challenges. The focus of my practice is OCD and Related Disorders, such as anxiety conditions, phobias, and compulsive eating behaviors.

As an OCD Specialist in Ventura, my training and experience is focused on helping people take their lives back from emotionally driven rituals and cravings that can create tremendous suffering. Specialization allows me to better serve clients with specific needs who have not been helped by generalist practitioners. Browse areas served or request a consultation.

Clinical Experience With OCD, Compulsive Behavior, and Anxiety Treatment With Teva Johnstone

I work with a variety of obsessive-compulsive themes and behaviors. While it's common to feel some embarrassment or shame about the nature of obsessions, I work effectively and sensitively with many types of OCD, including taboo themes that may be difficult to speak out loud. I strive to create a trusting therapeutic environment where you feel safe to share what troubles you so you can develop the skills to disempower your obsessions and stop ritualistic behavior.

Treatment for Obsessive-Compulsive Themes and Addictive Behavior:

  • Compulsive Rumination or 'Pure O' OCD
  • Contamination OCD
  • Religious and Moral Scrupulosity OCD
  • Relationship OCD
  • Sexual Orientation OCD
  • Just Right OCD
  • Harm and P-OCD
  • Fear of Going Crazy
  • Emetophobia or Fear of Vomiting
  • Social Phobia or Social Anxiety
  • Compulsive Eating and Binge Eating Disorder
  • Compulsive Internet Use and Internet Addiction: Gambling, Gaming, Social Media, etc.

Clinical Experience

I have been licensed to practice psychotherapy independently since 2021 and opened my practice the same year. I have provided mental health treatment to California residents since graduate school internships in 2011, and began specializing in the obsessive-compulsive spectrum in 2024 due to interest in the topic.

Advancing the Profession

From 2023-2025 I mentored early career pre-licensed therapists and provided contracted BBS clinical supervision to Associates in Ventura, Santa Barbara, and Los Angeles Counties. I enjoyed supervising beginning therapists and chose to step back from the role to focus on my own growing therapy practice.

In 2021 I held a volunteer Child, Adolescents & Young Adults committee position with the National Association of Social Workers and was selected as a Delegate for the NASW-CA Chapter.
