Dr. Greg Perri is the founding member of Kentucky Neuropsychological Associates (KNA), having initiated the practice in August 2020. He has practiced clinical neuropsychology for 15 years, primarily in the Louisville area. His primary clinical interests include mild traumatic brain injury/concussion management, differential diagnosis of dementia, and neurocognitive correlates of psychiatric conditions. Dr. Perri also has a significant background in forensic psychology and neuropsychology. He has been recognized as an expert witness (in over 100 total cases) across the Commonwealth of Kentucky, and has also previously testified as an expert witness in federal court cases.
Dr. Perri received his doctoral degree in clinical psychology at Widener University in Southeastern PA, with a specialization certification in the fields of neuropsychology as well as forensic psychology. He completed a two year internship as well as a post-doctoral fellowship in clinical neuropsychology (the latter was completed at Alfred I. DuPont hospital in Wilmington, DE).
Dr. Perri continues to conduct neuropsychological evaluations at KNA for adults as well as adolescents. Additionally, he is a staff neuropsychologist at Southern Kentucky Rehabilitation Hospital, where he has assisted in development of that hospital's recently constructed brain injury unit (set to open in July 2022). He has been a board member of the Brain Injury Alliance of Kentucky for over 10 years, where he is currently involved in a project to address the epidemic of the number of brain-injured individuals within the criminal justice system. Dr. Perri is currently overseeing multiple research projects related to the practice of neuropsychology, including one of which is being conducted in conjunction with the Spalding University clinical psychology graduate program.
A native Louisvilian, Dr. Perri was born a first generation Italian-American (Calabrese!) His leisure pursuits primarily revolve around the outdoors- including hiking, kayaking, and mountain biking. He also enjoys playing poker, and has been known to be a "foodie."
My name is Tonya Purtilar, and I am an administrative assistant at KNA. I have worked in the healthcare industry for over 15 years. Most of those years were spent working with the mental health and acquired brain injury (ABI) population. I previously worked with Dr. Perri at a clinical practice in the early 2010s. I received a Bachelor of Science degree in Human Resources in 2010 from Sullivan University. I am happily married to my best friend of 13 years. I spend most of my free time as a caretaker for my mother, as well as looking after my two grandchildren. My hobbies include crafting, billiards, and going to the lake. I have always had a love for working with brain injury patients, and strive to provide a compassionate experience for ABI survivors in our care.
Megan Chesher is a fourth year PsyD student at Spalding University’s clinical psychology program. Prior to her doctoral studies, Megan earned a master’s degree in clinical psychology at Loyola University Maryland. Megan has been part of the Kentucky Neuropsychological Associates team since Dr. Perri first opened the practice in 2020. Since then, Megan has completed clinical training at KNA under the supervision of Dr. Perri. She assists with neuropsychological evaluations and provides specialized services for brain injured patients. Megan’s psychotherapy approach includes a combination of cognitive rehabilitation to help individuals develop compensatory strategies and tools for improving functional competence in their day-to-day lives. In addition, she supports individuals as they come to terms with the impact of their injury and subsequently learn how to make the most of their abilities to enhance self-confidence and establish greater agency. Megan is also interested in neuropsychological assessment research, and she is currently working alongside Dr. Perri (dissertation co-chair) on a study exploring the use of a new assessment metric developed by Dr. Perri.
Throughout her graduate training, Megan has worked with diverse patient populations and numerous settings, including community mental health, long-term geriatric care, and inpatient substance use rehabilitation. Megan plans to continue her training in neuropsychological assessment and apply her skills and knowledge in geriatric care settings. She is passionate about providing services to older adults and their caregivers to help cope with old age, cognitive impairment, and loss of mental abilities.
During her free time, Megan enjoys taking her 3-year-old dog, Leo, on hikes and other outdoor adventures. Leo enjoys his leisure time almost as much as he enjoys working at KNA where he gets lots of attention, treats, and pets from clients and team members.

Autumn earned her Bachelor’s degree in Psychology and Criminology from the University of Kentucky in 2021.

This perspective has shaped her compassionate and attentive approach to patient care and administrative support.
After completing her undergraduate studies, Autumn shifted her focus from the mind to the body, earning her massage therapy license in 2025. She now specializes in injury-focused bodywork with an emphasis on holistic healing—integrating emotional, physical, and spiritual wellness at The Bodhi Tree.
