Julie Black, LMHC
“After every session, my hope is that kids, teens, and their parents leave feeling a little lighter, more hopeful, and more confident in their ability to weather life’s storms. I try to be the kind of person who sees the best in others and helps them discover that same light within themselves. When people truly begin to see the best in themselves, I believe they act in ways that honor that truth and stop getting in their own way.”
Karley Gabriel, PsyD
“ I have always had a genuine interest in each person’s unique story and a drive to help others reach their goals. I believe we all have our own strengths that can be best accessed when we are empowered and supported with compassion."
Caroline Mendel, PsyD
"I’ve known that I wanted to be a child psychologist since middle school! I had my sights set on this career because I naturally found myself supporting others, and I knew working with kids to help bring out the best in them would bring me joy."
Nikhil Nadkarni, MD
“Prior to becoming a doctor, I had spent time working in leprosy colonies in rural India and there I learned that the social consequences of illness can be profound and often more impactful than the medical consequences of illness. With this in mind, I found my way to Psychiatry, which is the discipline in medicine that I believe is the most attuned to the social determinants of health and the social consequences of mental and physical disorders.”
Michele Neuhaus, LMHC, LCAT, MA
“I enjoy helping people express their feelings. I am also passionate about helping my clients learn new ways to manage emotions and experiences that might feel overwhelming."
Dawn Nero, PsyD
"I'm passionate about helping parents understand how to support their kids, providing them with information and tools through testing and ongoing treatment."
Subina Sharma, LMHC-DP
“What inspires me most about my work is helping families build resilience and connection while supporting kids as they develop confidence and emotional balance.”
Charlie Xiao, PMHNP
“My inspiration to become a therapist was was raising a son with a serious mental illness. I aspire to use that lived experience to help children and their families overcome mental health challenges.

Why we chose Lake Success
Extending 119 miles from New York Harbor into the Atlantic Ocean, Long Island is the largest island in the contiguous United States. And on the island, tucked into Nassau County, is a village in the town of North Hempstead called Lake Success.
Fun fact: the lake itself isn’t manmade; it formed naturally as a glacial kettle hole during the last ice age. The 75-foot-deep lake is so central to the village, that before its incorporation the area was simply known as Lakeville.
Today, Lake Success is a quiet, affluent suburb that enjoys both easy access to New York City and everything residents need close to home — including pediatric mental health support from Brightline.
Lake Success is home to our second New York-based clinic and to many of the families we serve there. We’re honored to bring kids, teens, and parents the support they need to the community they love. It’s why we’re here. And it’s where you belong.
