Dr. Katie Fabius, PhD, is passionate about helping adults in Pennsylvania gain clarity, understanding, and direction through comprehensive psychological and neuropsychological testing. She supports individuals aged 18 and older who may be navigating challenges related to attention, memory, mood, and trauma. Whether someone is struggling with focus, emotional regulation, or cognitive changes after injury or illness, Dr. Fabius works to provide accurate assessments that lead to informed treatment and lasting improvement.

At LifeStance Health, Dr. Fabius offers specialized evaluations for ADHD, anxiety, bipolar disorder, depression, and trauma-related concerns, tailoring each assessment to the unique needs and goals of the individual. Serving patients throughout Pennsylvania, her approach is thorough and compassionate—designed not only to provide answers but also to empower individuals and their providers with actionable insights.

Dr. Fabius has particular expertise in working with individuals facing life transitions, including midlife and later adulthood. She is especially passionate about conducting assessments related to developmental disabilities, traumatic brain injuries, and cognitive or neurological concerns. Her evaluations are designed to clarify diagnoses and support meaningful clinical interventions, educational accommodations, or workplace strategies.

She frequently works with individuals from diverse backgrounds and experiences, including those with developmental disabilities and head injuries. In addition to adults of all genders, she serves patients navigating complex emotional or cognitive issues often overlooked without in-depth assessment.

Outside of her clinical work, Dr. Fabius enjoys running, traveling, exploring Philadelphia’s vibrant food scene, and spending time with family and friends. Her practice serves adults across Pennsylvania, and she welcomes new patients seeking greater self-awareness and support in their mental health journey.
