William Sumner
William Sumner has extraordinary gifts combined with an unusual mix of experience and knowledge.
While most other coaches come from one or two silos of expertise, William’s unique background combines military special operations, social work and mental health, Fortune 500 and small start-up executive business, along with ancient and new-age techniques and technologies. Such varied silos of knowledge seldom overlap — yet all come together to lead him on his powerful creative path of healing and teaching.
His vast experiences and tools all blend to provide him with astute awareness from a variety of angles. He has combined his knowledge, experience, and skills with his gift of intuition to create a distinctly unique system, with an extremely high rate of success, to guide people to the outcomes they want.
William specializes in people who want to change and transform their lives. His innovative use of newer technologies such as NLP (neural linguistic programming) has helped his clients make quantum shifts in their lives or their businesses — and these shifts stick. He is well known for taking on difficult challenges and helping people create their ultimate destiny.
William speaks to a wide variety of audiences and has a large diverse client base. In addition to the seminar experiences he offers, he was selected, by invitation after a world-wide search, by a well known prestigious motivational speaker to present seminars on his behalf; he has done this successfully throughout the United States, Asia, India, and Indonesia.
His trademarked coaching system Embrace the Inevitable
You™ involves the best-of-the-best within the self-help and motivational fields.
What truly sets William Sumner apart from other life coaches is his intuitive gift for helping people over that hump of resistance to live the life of their dreams. Most people who go to seminars, read books, or try coaching are not successful in maximizing the potential gains and possibilities. He provides precisely what they need to create truly profound, stunning, and incredible shifts in the lives of their loved ones as well as in their own.
