Chino Hills Psychological

Formerly Diamond Bar Psychological and Family Services

Relating with others through sincere interest and in a caring way has been shown to improve quality of life, while maintaining and managing the energy to do so is a bridge that many of us try to cross. Now that you are taking an active role with your health and well-being, I look forward to helping you discover what's best for you.
My research focused on relational trauma in early childhood and its influence on the regulatory function of the autonomic nervous system and corresponding personality structures. Research Panel: Allan Schore, Ph.D, UCLA, Avedis Panajian, Ph.D, Pacifica, Christine Lewis, Ph.D, Pacifica.
I suggest that a primary barrier to therapeutic change for the client who has experienced relational trauma in early childhood is the limited ability to use one's associative memory during interpersonal exploration. - M.W. Summerlin, Ph.D (Dual Origins of Personality).
