Historically, I have offered psychological assessment services for individuals from birth through 25 years of age and some testing for adults over 25. Assessments included neuropsychological, psychoeducational, diagnostic and developmental evaluations. I have also conducted many Independent Educational Evaluations. As my practice has gotten busier, I've taken more of an administrative role. There are additional therapists, testing psychologists and medication management providers in my office. Please feel free to reach out if I am not accepting new clients as we may have other providers available to meet your needs.
I am currently the executive director or Gunn Behavioral Care of CA. My office specializes in traditional talk therapy, neuropsychological, psychological and developmental testing and medication management. We frequently work with children and adults suspected of ADHD, Autism, depression, anxiety and other common behavioral health diagnoses.
We believe that behavioral health should be accessible to all people, including children and adults. Our mental health providers invite you as the client or parent to be intimately involved in the treatment since you are the expert in yourself and/or your child. We will partner with you to emphasize your strengths and build upon any weaknesses.
