Dr. Luisa Hernandez Medellin Discusses NESCA’s Miami Launch

NESCA recently opened its latest pediatric neuropsychology office in Coral Gables/Miami, Florida, headed up by Dr. Luisa Hernandez Medellin. I had the opportunity to speak with Dr. Luisa Hernandez Medellin to get to know more about her background, the current evaluation landscape in South Florida, Latin America, and the Caribbean, and to hear from her what unmet needs NESCA addresses in bringing its expertise to that region.

Tell us about your background and how you chose to become a pediatric neuropsychologist.
I was born and raised in Mexico City in a family that valued service and helping others. As a teen, I considered becoming a missionary nun because I wanted to travel to deliver services and support to children in need. During those years, I spent time in Cuba, Nicaragua, Guatemala, and Costa Rica, where I witnessed numerous disparities in the way people lived. That experience shaped my commitment to serving children and families.

When I returned to Mexico, I explored different careers, including teaching and medicine, as my father was a doctor, and eventually landed in psychology almost by chance—but it felt like home as soon as I discovered it. Later, when I moved to Miami, I completed my bachelor’s degree and entered a doctoral program in child psychology. During my training, I discovered neuropsychology, and it was a perfect fit: a way to combine psychology with the medical world, caring for both the mind and the body of an individual.

I trained at Jackson Memorial Hospital, where I fell in love with pediatric neuropsychology, working with children with neurodevelopmental disorders in both inpatient and outpatient settings. That experience set the foundation for my career. Since then, I’ve worked in hospitals, private practice, and now with NESCA, where I get to provide high-quality evaluations in a compassionate way that will help children and their families have a path to move forward on.

What is your philosophy when working with children and families?
I treat every child as I would my own. I’m a mother of three, all neurodivergent in different ways, so I understand how hard it can be to navigate the challenges of having children with disabilities while also loving them so deeply. My role is to get to know each child who comes in for an evaluation—what makes them unique, what’s important to them—and to help uncover what’s happening so they can flourish.

How do you feel neuropsychological evaluations benefit individuals and families?
Evaluations give us a deeper, objective understanding of a child’s strengths and challenges. Parents often come to me worried that they’ve done something wrong that caused their child’s struggles. I reassure them that no one is at fault. The goal is not to find problems or identify something or someone to blame; rather, it’s to identify the root cause of a child’s challenges while also highlighting each child’s strengths. It’s about finding the “lights AND the shadows.” For example, if a child struggles in math but loves music, we lean into music as a source of joy and growth for the child while knowing how to  properly provide support in areas like math, that may be more stressful.

How do you approach parents or caregivers who are resistant to the evaluation process or the possibility of their child receiving a diagnosis from it?
In Miami, many families are hesitant about their child receiving a diagnosis(es). I take the time during the intake process to listen to their concerns and gently plant seeds about the types of issues we may be seeing. That way, parents aren’t shocked during the feedback session where they learn the findings from the evaluation, which may include one or more diagnosis(es). It helps them process the information and reduces their fears. I emphasize that neurodivergence isn’t caused by parenting choices or styles, screen time, or the Covid experience. It’s just how a child is wired. My focus is on supporting families and children and building hope with new information from the evaluation.

How did you connect with NESCA, and what excites you about bringing NESCA to Miami?
While considering a move to Boston, I met NESCA’s founder and director, Dr. Ann Helmus, and our conversation felt like meeting a kindred spirit. She reminded me of my attending supervisor from Jackson Memorial Hospital in that they both expect very high quality evaluations, really care about their patients, and truly value the quality of the training provided to their trainees. That’s not always the way with providers, so that was very important to me.

She shared that NESCA was planning to open a Miami office, which felt like the perfect match. Now, I get to help NESCA bring its 30 years of expertise to our region, while I’m also contributing my own 20 years of experience right here in Miami. Together, we’re offering high-quality, culturally-sensitive evaluations in both Spanish and English.

Why does Miami need a practice like NESCA?
The system here in South Florida often creates delays in the identification of developmental, emotional, or learning disabilities. Pediatricians sometimes use a “wait and see” approach; bilingualism is sometimes mistaken for a speech delay when it’s really a sign of autism; and schools often face huge, lengthy backlogs for testing students.

It can be tricky to find the right resource or professional to help identify challenges early on. Neurologists tend to be trained in the brain as “hardware,” whereas we examine the brain’s operating system and how it functions when there is a brain injury, a developmental disorder, or other issue. More often, they look to scans and imaging for answers, where we look at the child’s wellbeing and growth, especially when there is a more complex presentation that may lead to several diagnoses, like ADHD, autism, and anxiety, all co-occurring. And due to productivity pressures in large Miami hospitals, they are only able to see patients for 15 minutes or so and often via telehealth.

And again, with our medical system not being optimized, there is a lot of overwhelm among pediatricians who are forced to operate in a factory-like system. Many people here in South Florida don’t actually have a dedicated pediatrician who knows them and their families. It’s more of a walk-in urgent care system, and that means there is no follow-up in six months or even a year to see how a child is progressing or not. No one is tracking them and is dedicated to their developmental well-being. This is another reason for the frequent delays in diagnosis here.

Because of all of these issues, too often, families don’t receive timely or comprehensive evaluations, and diagnoses and services are delayed. NESCA offers an alternative: in-depth, individualized assessments that consider the whole child—what their lives look like and how they do in school, at home, and in the community. NESCA coming to Miami is filling a very large gap in getting families the answers they are looking for and getting children the support they need to thrive.

What do you evaluate at NESCA in Coral Gables?
I focus primarily in pediatric neurodevelopmental disorders, ADHD, Autism Spectrum Disorders, and learning disabilities, providing evaluations and highly tailored recommendations for interventions. I have also been training practicum students in the Miami area, which we will continue to do as part of the NESCA practice in Coral Gables. There are currently only two sites in Miami where doctoral-level students can train at a practicum level in pediatric neuropsychology, and one of them is now NESCA.

What are your plans for working with schools and international families?
International families and private schools are actively seeking support for their students. Many families from Latin America and the Caribbean face limited resources in their home countries. They come to NESCA for specialized, highly personalized evaluations and recommendations on how to support their child or student at home or in school, in their country. NESCA in Miami will provide these families with the guidance and expertise they need—tailored to their cultural context and delivered with compassion.

Any final thoughts?
NESCA offers families in South Florida, Latin America, and the Caribbean the best of both worlds. We’re bringing NESCA’s legacy of excellence from 30 years of practice in New England, along with my decades of experience living and practicing in Miami, to serve families in this diverse, multicultural community. My goal is simple: to help every child be understood, supported, and given the guidance and tools necessary to thrive.
