Samantha Warner, Psy.D. (she/her) is a pre-licensed Counseling Psychologist who grew up in the Philadelphia area. She obtained both her Master’s degree in Counseling Psychology (Clinical Mental Health concentration) in 2020 and her Doctorate in Counseling Psychology in 2025 from Holy Family University in Newtown, PA. Her therapeutic approach is rooted in combination of Person Centered/Trauma Informed practice. Dr. Warner and her clients work together to create an environment of empathy, genuineness, and positive regard, allowing clients to explore their concerns and work towards their goals in a way that also allows them to feel physically and psychologically safe. When navigating coping skills around anxiety, depression, or stress, Dr. Warner will often use several different tools in an ever-growing toolbox. These may include reviewing daily routines (exercise, sleep hygiene), mindful techniques (breathing skills), reading and journal prompts, or therapeutic games. She has also spent several years volunteering and working with members of the LQBTQIA+ community as a therapist, advocate, and ally. While she has worked with many individuals throughout the lifespan, Dr. Warner’s primary focus has been working with adults along the wide expanse of neurodivergence. This would include dual diagnosed adults (those with an Autism Spectrum Disorder and/or an Intellectual Developmental Disorder diagnosis in addition to a mental health diagnosis) as well as those adults who were not diagnosed as neurodivergent until later in life. In the area of psychological testing and assessment, Dr. Warner has training and experience in assessing neurodevelopmental disorders in adults (IDD, ASD), comprehensive diagnostic batteries for further psychotherapeutic interventions, and initial evaluation for neurocognitive concerns (dementia, Alzheimer's, etc.). Outside of practicing therapeutic interventions, Dr. Warner also serves as an adjunct instructor at both Holy Family University and Chestnut Hill College.
