    Dr. Max Shmidheiser


    Greetings! I am the owner and founder of Oasis Neurobehavioral Health, LLC. I am a clinical psychologist and licensed to practice in Pennsylvania (PS016863), and I am Board Certified through the American Board of Professional Psychology (ABPP) in clinical neuropsychology. I am also certified through the Brain Injury Association of America as a Certified Brain Injury Specialist- Trainer (CBIST). I have a master’s degree in bioethics (MBE) from the University of Pennsylvania, and I currently serve on professional ethics committees. I earned my Doctorate in Clinical Psychology (PsyD) from Widener University’s Institute for Graduate Clinical Psychology (IGCP), and I completed a two-year clinical post-doctoral fellowship through Harvard Medical School and Cambridge Health Alliance.

    I have been formally trained in Cognitive-Behavioral Therapy (CBT), Psychodynamic Therapy, mindfulness-based interventions, and other evidence-based therapeutic approaches including Motivational Interviewing. I have over 15 years of experience working in psychiatric and rehabilitation hospitals, counseling centers, and independent private practice. My clinical appointment prior to starting Oasis Neurobehavioral Health, LLC, was serving as the Clinical Advisor of MossRehab Concussion Center, which I co-founded at MossRehab Hospital over ten years ago, and clinical neuropsychologist at Drucker Brain Injury Center at MossRehab. Please feel free to contact me if you have additional questions!


    Taking steps to ensure that your therapist is a great fit for you is very important, which is why free 10-minute consultations are offered in advance of a first session. Please feel free to contact me to ask questions, set up your first appointment, or see if the services on offer are a match for what you are seeking.

    Inspirational Quotes

    “Perfectionism is a self destructive and addictive belief system that fuels this primary thought: If I look perfect, and do everything perfectly, I can avoid or minimise the painful feelings of shame, judgment, and blame.”

    Brené Brown

    “Somehow we’ve come to equate success with not needing anyone. Many of us are willing to extend a helping hand, but we’re very reluctant to reach out for help when we need it ourselves. It’s as if we’ve divided the world into “those who offer help” and “those who need help.” The truth is that we are both.”

    Brené Brown

    “Vulnerability is not winning or losing; it’s having the courage to show up and be seen when we have no control over the outcome.”

    Brené Brown
