I have also spent hundreds of hours reading, attending webinars, and following additional training courses, too extensive to list above. However, the vast majority of my focus for Continual Professional Development has been guided towards OCD.

My journey towards becoming a therapist started with several challenging personal life experiences, including a very close bereavement, relationship issues, a medical health diagnosis (life-changing at the time), and bouts of OCD that I would experience in waves. I recognized how much of a negative impact these external factors had on my life, causing the onset of my obsessive-compulsive symptoms, so I decided that enough was enough. I had to start to make some changes. In addition, I understood that I had to take responsibility for myself to begin regaining control over my life once again.

I knew that I needed a healthy mental frame, but I was struggling and starting to lose hope; the obsessions and compulsions left me feeling like a bat hanging upside down. I felt bewildered and utterly hopeless, with nowhere to turn. I soon realized that only I could take the first step and put a full stop to my suffering by taking responsibility for my own life. I knew that I needed the right tools to overcome this and to find them, I needed the right therapist and professional support.

After a rather negative experience with a therapist, I realized the importance of the relationship between the therapist and client. From that day onwards, I decided that I would train to become a therapist due to my own negative experiences within Psychotherapy and the impact this had had on me both generally and on my OCD. I felt passionate about making a positive difference in the therapeutic and counselling world.

All I wanted at the time of my suffering was a space to be heard, entirely without judgment, and to be given the practical skills to start regaining control of my life. Finally, after much time and persistence, I managed to find someone to offer me some, but not at all, of the skills that I needed. Still, it was enough to get me back on the correct path, one toward hope which ultimately led them to become a fully qualified therapist.

I pride myself on my approachability, down-to-earth nature, and ability to connect professionally and personally with people. My approach to therapy for OCD includes both a safe and non-judgemental space to talk while focusing on practical and applicable knowledge and tools to help successfully manage OCD. I am also a firm believer that even if we have some of the most valuable tools, they must be practiced and sharpened to be most effective. Recovery takes work, and I enjoy supporting my clients along that journey.

I feel a great sense of satisfaction when a client leaves my therapy room feeling listened to, supported, and confident that they can start working towards a more fully functioning self.

Jim Callner

Founder of OCDAF, Social Media Expert and Author

Jim has been raising positive awareness of OCD for many years and is the founder and director of the OCD Awareness Foundation in America. Jim also has extensive experience and qualifications in the film industry, which he now channels into creating short films and coaching videos to help sufferers of the condition, based within his own recovery of OCD. Jim is also a popular author of the books: "It's a Matter of Trust," published in 2016, and "Positive Posts for OCD and Anxiety," more recently published in 2021. In addition, Jim's videos and social media content are regularly viewed by tens of thousands of people with overwhelming praise.

The onset of OCD came for me in 1982 at age 29. To this day, I stay on top of my recovery with continued CBT/ ERP, spiritual, medical, and holistic therapies and treatments, consequently emerging as an educator and a public speaker specializing in OCD and anxiety. I am very proud to affiliate with The OCD Treatment Centre and am looking forward to the continued effort to raise accurate and positive awareness of OCD recovery. We have many exciting projects in the pipeline, including writing the third book, creating online OCD-specific digital content, and making a positive difference in the OCD community.

I started my college teaching and professional filmmaking career in my early 20s. Since then, I have earned over 30 national and international film festival awards and critical acclaim for writing and directing films about physically and emotionally challenged individuals. In addition, I was commissioned by the International OCD Foundation to make the first dramatic educational film about a child with OCD, The Touching Tree.
I currently provide inspiration and recovery techniques through regularly uploading OCD Coaching Videos and words of hope. My articles can be found at, Facebook, YouTube, and other social media platforms. I am also the co-founder and president of the Awareness Foundation for OCD. I live with my wife Jeanine by the ocean in northern California, USA.

I am the proud author of two OCD-specific help books. My first publication is called ‘It’s A Matter Of Trust.’ This hopeful and inspirational memoir is a warm and casual account of my recovery process. My second book is called ‘Positive Posts for OCD and Anxiety,’ which was received equally well by the OCD community. My care was multifaceted, including hospitalization, Cognitive Behavioural Therapy (CBT), Exposure Response Prevention Therapy (ERP), and an array of innovative approaches.

I have chronicled my three decades of getting the right help while living with OCD with compassion, empathy, humor, and wisdom. I found that OCD robbed me of trust and infused me with fears and phobias about people, places, and things and debilitating anxiety. I didn’t trust life. I regained that trust by using helpful tools to reclaim my power—to trust myself again. In my books, I share those tools to help with your recovery.
