As a family law attorney in the Thousand Oaks area, I have referred many clients to Dr. Summerfield over the years and uniformly, I receive very positive feedback from those clients regarding him.  Uniformly, he is described as kind, caring, responsive, knowledgeable and practical.

I’ve been referring my patients, friends, and family to Lester Summerfield since 1983, when I first began my private Ob/Gyn practice in the Conejo Valley.  Lester has become a dear friend through the years, also helping me navigate through the psychological hurdles of life.  He is truly a brilliant psychologist.  Furthermore, Lester is trustworthy, honest, caring, intuitive, and direct.  I continue recommending him without any reservations.

Dr. Lester Summerfield is truly one of the finest psychologists in Southern California. In my 30 years of neurology practice, I have had the opportunity to work with many psychologists. What sets Dr. Summerfield apart is that he brings a wealth of knowledge, understanding, clarity, and compassion to patients. His therapeutic insight has rescued countless of my patients over the years. In particular, his care of individuals with traumatic brain Injury, attention deficit disorder, and various mood problems has been professional and outstanding. He is well established and trusted in our community. I have no reservations in recommending Dr Summerfield for his abilities as an child, adolescent and adult psychologist for individual and family therapy.

I feel so fortunate to be seeing Dr. Summerfield. Having had difficult times lately including the death of my Dad. I find him to be compassionate, intuitive, very intelligent, and understands me better than I do. Thankfully, he has a great sense of humor when needed. If you don't really want to know, don't ask - he is a compelling straight talker with excellent advice. I don't get away with much. Anyone who is about to see him is very lucky.
