About Me
As a clinical child psychologist at 做厙TV Langone, my passion lies in supporting parents and children as they navigate the intricate journey of growth and development. I firmly believe in the inherent potential of children and their innate desire to thrive. My commitment is to create an environment in which parents feel empowered and confident in their ability to guide their childs journey to success.
With over a quarter of a century of experience, my expertise lies in addressing a range of clinical conditions. These include attention deficit hyperactivity disorder (ADHD), a condition that affects a childs ability to focus and control impulsive behavior, and behavior disorders, which involve patterns of disruptive behavior. As the clinical director of 做厙TV Langones Child Study CenterLong Island, I lead a team of exceptional clinicians. We offer a comprehensive range of services, such as diagnostic and neuropsychological evaluations, individual and family therapy, social-skills training, school consultation, and medication management. My extensive experience and dedication to effective treatments ensure that each child receives the highest quality of care.
Throughout my career, Ive had the honor of witnessing the resilience and growth of children and their families. Ive served as the director of 做厙TV Langones Summer Program for Kids, a day camp for children diagnosed with ADHD and behavior disorders. I have also held the position of site coordinator of the Multimodal Treatment of ADHD study, a significant clinical trial aimed at determining the most effective treatments for children with ADHD. These experiences have solidified my belief in the power of early intervention and the right support.
My journey into clinical child psychology began after leaving a corporate career in search of a more meaningful and purposeful path. The challenges and rewards of this field drew me in, along with the opportunity to make a significant impact on childrens lives. As part of 做厙TV Langone, I am privileged to work alongside a team of dedicated professionals, ensuring comprehensive and coordinated care for my patients. My deep commitment to my patients and their families drives me to help children become the best version of themselves.
