“Because I’m married to Bill, I see the incredible attention and time he has devoted to developing and supporting his Master Mentoring courses. I encourage you to take advantage of this extraordinary one-in-a-lifetime opportunity to learn from him. Bill’s grounding in the 3 Principles is deep and has evolved from a direct, long-standing relationship with his mentor, Sydney Banks. Bill’s knowledge of and experience in adolescent and adult psychiatry, psychology, medicine, psychosomatic medicine, addictions and the neurosciences, combined with his 3 Principles understanding, make him an unparalleled teacher. Working with him will expand your spiritual understanding and provide valuable information for working with ANY and ALL, I repeat ANY, and ALL clients. As I’ve lived by his side for twenty years, I’ve watched Bill work miracles with his individual clients. His magic is a combination of his absolute “knowing” about the universal principles that are the source of life, his complete faith that human beings are never broken and have nothing lacking, and his mind-blowing compassion. I simply have not witnessed a more loving human being with a clearer spiritual understanding. Bill is a perfect example of a man who lives what he teaches.”

– Linda Sandel Pettit, Ed.D., Mentor to Intuitive-Creative Women, Author and Speaker www.lindasandelpettit.com

“Dr. Pettit has an incredible depth of experience and wisdom both in the Three Principles and modern medicine. His generous spirit and kind heart make learning with him a profound experience. There seems to be no end to his knowledge and yet his humility makes it very accessible for everyone to follow. Dr. Pettit has helped me deepen my own understanding and given me incredible language and resources to share this experience with others. I am honored to call him teacher, mentor, and friend.”

– Chana Studley, Three Principles Practitioner, Speaker, and Author

I’ve had the great fortune to be mentored by Dr Bill Pettit, both on some of his programmes and personally. It is not dramatic to say that his guidance has been life changing for me. His humour and from the hip delivery is exactly the sort of mentoring that helps one level up to a whole new dimension. Bill has shown me that fully embracing the spiritual aspect of the Three Principles and not being ‘gun shy’ about sharing that with business leaders as well as my own mentee’s, is in fact pioneering. Personally I have experienced deep peace and unheard of rest following a particularly moving session which has enhanced my performance in my business and deepened my relationships. I see all aspects of my life with different eyes.

– Jacqueline Hollows MSc, author of Wing of an Angel

“From the moment I heard Dr. Pettit share about the three principles and particularly anxiety and love letters, I was intrigued. I was blown away by his kindness, knowledge, wisdom, and take on psychological conditions. I had never heard a psychiatrist talk about how we are never broken or lacking in terms of mental health. I loved how Bill continually points back to how the human system is benevolent and beneficent. He helped me see mental health in a whole new light! Listening to his stories of hope my heart feels so full. At first, it was just for my own healing, but when I transitioned from a school psychologist to a three principles practitioner I felt a bolt of insecurity and thought maybe I needed to get my Ph.D. What came up was that I wanted a Ph.D. in the principles! The first mentor that came to mind was Dr. Pettit. I found great value in Bill’s One Cause One Cure courses. Working with Bill individually when he offered his ALERT certification was one of the best decisions of my life. I thought our sessions would mainly be me asking his guidance regarding clients, but I also found myself talking about myself and Bill’s listening and guidance were so welcomed. I felt seen, understood, and cared for. I felt like Bill was not only a mentor but a friend. Bill helped deepen my understanding of the principles and I am grateful that he continually pointed back to Syd’s work. Prior to working with Dr. Pettit, I’m embarrassed that I hadn’t read all of Syd’s books but I can proudly say now that I have and have read many two to three times. The picture of me holding The Missing Link is in dedication to Bill and Syd. If you’ve worked with me you’ve definitely heard me quote my amazing mentor- Dr. Bill Pettit who has not only transformed my own wellbeing, but transformed my practice as a three principles practitioner. I am forever grateful to Dr. Pettit! Thank you, thank you, thank you!”

– Lily Sais, Three Principles Practitioner


“When I met Dr. Bill Pettit several years ago, I sensed that he was a like-minded colleague. I had already been studying the 3 Principles of Mind, Thought, and Consciousness, after an illness nearly took my life. Bill was kind enough to invite me into a small group of psychiatrists who were consulting with him regularly; I had also been part of the Healers’ Clinic that he and his very wise and accomplished wife, Dr. Linda Pettit, facilitated. Plus I’ve joyfully shown up for every course he’s offered. This has all helped me deepen my understanding and move forward in my own life. There’s so much I love about Bill – especially the way he speaks about mental/spiritual well- being and its effects on overall health. In responding to people’s questions, he shares from his heart. Even while teaching from his vast experience, he remains a student of life. He is an amazing collector and curator of facts, figures, and ideas, somehow laying these out in ways that people can meaningfully grasp. Insights come, when listening to him. I am grateful to know Bill as a colleague, mentor, friend, and fellow “punster.” He has helped me shed a ton of worry, insecurity, and hurt; time with him is priceless. I invite you to see what might happen in you, through any of Bill’s programs, courses, or consultations.”

– Pam Pappas MD, Integrative Psychiatrist

“Bill Pettit’s Master Mentoring Courses are not only a thorough and life-changing experience, but like Bill himself, they are entertaining and inspiring.”

– Steve Chandler, Author of Time Warrior

“There are magic moments in life that literally stop you in your tracks, give you time to reflect on how wonderful they are. This happened in my friendship with Dr.Bill, a deep connection with no boundaries, stories to be told, wisdom to be shared , tears and laughter to be drunk. I am indeed a lucky man.”

– Rob Hollows, Commercial Director

“You can’t discuss master mentors without saying the name Dr. William Pettit. His humility and heart are visible and tangible in his every move. I was blessed to spend some time with Dr. Pettit and had two of the most significant insights I’d ever have before. One of my lived experiences is my education. Secondly, he helped me see that sadness and well-being can exist simultaneously. Dr. Pettit was also there to extend a hug and a smile during one of my saddest moments. His ability to impact and guide comes through in his mentorship courses, and anyone attending will benefit in so many ways.”

– Rob Cook, Founder, The Impact Zone

“When I first met Dr Bill Pettit, I wanted to learn how he had such an extraordinary track record of success as a mental health professional. In the first ten minutes of listening to him, I got it. He’s so sure everyone is already sane (has innate mental health and well-being), you’d go nuts trying to convince him that you’re nuts! In the years since then, I’ve watched him deepen as a human being and his work become more and more accessible to all. Simply put, Bill is the real deal.”

– Michael Neill, Bestselling Author of The Inside-Out Revolution and The Space Within

“I had the pleasure of spending several days alongside Dr. Bill Pettit both in Prague and Bucharest and the wisdom, presence and love with which he comes into every interaction is palpable and touches people deeply. He has so much experience and has helped so many people find their innate health that he could be considered a celebrity, yet he remains incredibly humble and keeps being a lifelong student of Three Principles. The combination of his deep knowledge of the workings of human body and brain with understanding the spiritual principles operating behind the scenes gives his words and impact a unique touch. But with Bill the words are not what matters. It is always the feeling behind the words that creates true miracles. I am grateful to have him in my life.”

– Martin Jotov, Director of Technology Holding IQS Group, co-founder of Understanding Mind NGO

Without a doubt, William Pettit Jr. understanding of the connection of Universal Mind-Body and its relationship to the role of Thought is as one of the leading experts in the world. It has been my privilege to witness his profound sharing in webinars or joint talks that have gone around the world, and he has always stepped up to the plate with his caring and fun-loving nature whenever I have asked him to be a guest speaker on these many webinars. As a 3 Principles Educator in the field of addiction and mental health, I have personally witnessed transformations of the soul or human psychological breakthroughs by the lucky participants.

– Harry Derbitsky, www.acttraining.biz

“I first heard Bill talking in a three principles course I have studied in and immediately wanted to hear more. The wisdom, experience, and loving attitude towards listeners and life itself was breathtaking. He kindly agreed to speak at two events in the Czech Republic and Romania for our NGO. I will never stop marveling at how perfectly he sees the innocence in all our human acts and behaviors, and how spotlessly he sees the Three Principles work in life. He and his wife taught me to listen to the wisdom of people I speak with. It is an honor knowing him personally and learning from him. What a beautiful person, what a beautiful soul, what a beautiful example of kindness in this world.”
