Developmental - Behavioral Pediatrics Fellowship Program

Our three-year fellowship is an ACGME accredited program whose purpose is to prepare you for a career in Developmental-Behavioral Pediatrics including patient care, teaching, research/scholarship, leadership and advocacy.  Our program is located in the Norton Children's Developmental - Behavioral and Genetics (formally known as the UofL Weisskopf Center) which was established in 1966 and provides state of the art interdisciplinary diagnostic and treatment services for children with developmental and genetic disorders. Faculty and clinicians include developmental-behavioral pediatricians, psychologists, speech-language pathologists, occupational therapists, and social workers. 

Fellows receive exceptional clinical training in our rich interdisciplinary environment.  They provide evaluation and care for children with a range of developmental and behavioral conditions such as autism spectrum disorder, developmental delay, feeding disorders, learning disability, fetal alcohol syndrome, fragile X syndrome, tourette’s disorder, behavior and mood disorders, and attention deficit hyperactivity disorder. 

Our training program consists of a comprehensive clinical experience, primarily based at the Norton Children's Developmental - Behavioral and Genetics practice and includes rotations with other service lines such as genetics, child neurology, and child & adolescent psychology and psychiatry.  Fellows have the opportunity to graduate with a Master’s degree via the Clinical Investigation Science Program in the School of Public Health and Information Sciences. Fellows continue in advanced clinical and leadership training during the 2nd and 3rd years, and will select a research project with increasing time allotted over the course of the 3-year program.

Upon successful completion of the fellowship program, our fellow(s) will be eligible to sit for board certification in Developmental-Behavioral Pediatrics.

P. Gail Williams, M.D.
Professor of Pediatrics
Program Director Developmental-Behavioral Pediatrics Fellowship

P. Gail Williams, M.D. is a professor of pediatrics at the University of Louisville.  She is a board certified developmental/behavioral pediatrician who performs neurodevelopmental evaluations at UL Weisskopf Center.  She works in a multidisciplinary setting and sees children of all ages who present with autism spectrum disorders, learning disabilities, attention deficit hyperactivity disorder, Tourette’s disorder, and intellectual disability.  She also provides biomedical consultations at the Norton Healthcare/University of Louisville Autism Center.  While her primary responsibilities are clinical, she has authored articles on a variety of topics, including the association of autism with neurofibromatosis and Fetal Valproate Syndrome, medical homes for children with ASD in Kentucky, and use of psychotropic medications in the Kentucky pediatric Medicaid population. She has participated in several clinical drug trials to assess the efficacy of medication use in treating behavior concerns associated with autism.  Dr. Williams is the coordinator of the pediatric resident rotation in developmental/ behavioral pediatrics and chief of the developmental medicine division at the UL Weisskopf Center.  She has lectured regionally and nationally on a variety of developmental topics.  She is chair of the Alliance for Pediatric Mental and Behavioral Health of Kentucky and member of the Society for Developmental and Behavioral Pediatrics, Kentucky Advisory Council on Autism Spectrum Disorders, the Kentucky Medical Association and the Greater Louisville Medical Society.  She served on the Executive Committee for the AAP Council on Early Childhood and has authored several AAP policy statements and technical reports.

Joseph Hersh, M.D.
Professor of Pediatrics
Director,  Weisskopf Center
Clinical Geneticist
Neurodevelopmental Pediatrician

Pursuing a career in academic medicine has been rewarding, providing opportunities to function as a clinician, educator and clinical investigator.  Receiving postgraduate training in genetics and neurodevelopmental disabilities has afforded me the opportunity to diagnose and address associated medical conditions in children with genetic or developmental disorders.  Working in a setting that offers diagnostic and treatment services for individuals with genetic and developmental disorders also has created an environment to make valuable contributions in educating young medical professionals and community physicians and to contribute to the medical literature.

I completed my medical degree at the University of Missouri and pediatric residency at Cincinnati Children’s Hospital and the University of Connecticut, followed by fellowship training at UConn and three board certifications.  For over three decades, I have been a faculty member at the University of Louisville and am currently Professor of Pediatrics and Director of the UL Weisskopf Center.  Comprehensive genetic and developmental services through a variety of subspecialty and outreach programs, and telemedicine are provided by me, and I oversee laboratory services at UL Weisskopf Center in which cytogenetics, FISH and chromosomal microarray analysis are performed.

I coordinate the first-year medical school genetics and molecular medicine course and am our school’s APHMG representative.  Along with other professionals at UL Weisskopf Center, training in genetics and development is provided to pediatric and med/ped residents and medical students. 

Serving as a member of the AAP Committee on Genetics for six years afforded me with the opportunity to develop new and revised policy statements on several genetic disorders.  The Center has been a source for tremendous personal growth in the pursuit of a successful academic career in medicine.


Scott D. Tomchek, PhD, OTR/L, FAOTA
Chief Occupational Therapist
Professor of Pediatrics
Assistant Director, Weisskopf Center

Dr. Tomchek has over 25 years of pediatric clinical practice experience in various settings.  He received his post-professional master’s degree in Occupational Therapy from the State University of New York at Buffalo in 1993 with a concentration in early intervention.  His Doctor of Philosophy in Rehabilitation Sciences from 2005 is from the University of Kentucky in 2005.  There, he focused his studies on interdisciplinary rehabilitation research with a cognate emphasis in neurological aspects of individuals with developmental disabilities.  His dissertation was titled “Characterizing Sensory Processing in Autism Spectrum Disorders.”

Clinical practice and research focus has centered on individuals with autism spectrum disorder, including diagnostic evaluation, clinical assessment, and therapeutic interventions.  The focus of these activities is the sensorimotor aspects of development and their impact on engaging in occupations.  These clinical diagnostic and treatment specializations in autism have been recognized by invited lectures, authorship and subsequent publications relating to sensory processing findings in ASDs (Dean et al., 2018; Little et al., 2016; Tomchek, 2010; Tomchek et al., 2014, 2015. 2018), sensorimotor assessment with individuals with an ASD (Tomchek, 2000; Watling & Tomchek, 2018) and collaborative models on a care team for individuals with ASD (Geis & Tomchek, 2000; Dubuque & Tomchek, 2018; Tomchek et al., 2017).  Dr. Tomchek has also co-authored the practice guideline (Tomchek & Koenig, 2016) and official statement (AOTA, in press) of the American Occupational Therapy Association related to practice with individuals on the autism spectrum.  In addition to clinical roles at UL, Dr. Tomchek developed and coordinated statewide training of early intervention providers on early identification and evidence-based practices of children with ASD. This work has been expanded to direct the KEIS State Systemic Improvement Plan provider training and mentorship program to enhance implementation of evidence-based coaching practices during early intervention services with children with developmental delays and their families.

Maria L. Mendoza M.D.
Assistant Professor of Pediatrics

Maria Mendoza, MD is a board certified developmental/behavioral pediatrician whose passion for serving children with special health care needs has found its home at the University of Louisville, Division of Developmental-Behavioral Pediatrics. Having completed medical school at the University of the Philippines College of Medicine and pediatric residency at Penn State Children’s Hospital, she moved to New York to pursue fellowship at Cohen Children’s Northwell Health. She joined the team at Weisskopf Center in 2014 and since then has been an active faculty member, serving as mentor to both residents and fellows.

During her first few years at Weisskopf Center, she led the Developmental Pediatric Follow-up Clinic for high risk neonates that augmented the services provided by the established NICU clinic. Her focus has been on the long-term follow-up of children with neonatal opioid withdrawal syndrome and small for gestational age. She also served as the chief developmental pediatrician at the University of Louisville Physicians- Brownsboro office where, together with neuropsychology, children with complex ADHD, traumatic brain injuries, and spinal cord injuries were seen for psychopharmacologic and behavioral interventions.

In 2019, she served as faculty advisor for a resident-led study that looked into the effects of different categories of in utero drug exposure in the neurodevelopmental outcomes of infants with neonatal abstinence syndrome. She currently serves as faculty mentor to one of the DBP fellows whose focus is on the development of screening competency for elopement and wandering in children with autism spectrum disorder.

In July 2020, Dr. Mendoza completed the UofL Leadership and Innovation in Academic Medicine program during which time, she and her colleagues from other department, looked into innovative ways of increasing patient access to timely medical care.

To deliver current, evidenced-based, compassionate and family-centered care has been one of Dr. Mendoza’s clinical missions ever since she took the road less travelled called Developmental/Behavioral Pediatrics. Her ultimate goal as a clinician-educator is to inspire more pediatricians to take the same steps towards this path.
