Connie Sargunam, LLP
connie@behaviorhealthpartners.com
Connie Sargunam is a Limited Licensed Psychologist who has worked in the field for over 11 years and provided outpatient services since January of 2015. She has experience treating children who struggle with anxiety, depression, oppositional behavior, Attention-Deficit/Hyperactivity Disorder, Post-Traumatic Stress Disorder, and developmental disabilities including cognitive impairment and Autism.
She also has experience working with children in the foster care system, from families of divorce, and with a history of trauma. She enjoys working with children of all ages as she is intrigued by each person’s unique perspective on the world and understands that life can be overwhelming at any age without the necessary tools to navigate life’s challenges. Nonetheless, she believes that people are always doing the best they can in the moment and utilizes the strengths of the family to help each child be successful.
It is with patience, understanding, and compassion that she strives to help each child recognize his/her worth and potential along with providing the behavioral strategies to make changes that are meaningful to the individual. In her experience, children often underestimate their own power and ability to make the changes they desire. Her favorite part of therapy is watching as the client begins to believe in him/herself and recognize the inner strength that was there all along. Mrs. Sargunam is directly supervised by Dr. Christie Nutkins.
