ABOUT DR. Taylor Murphy

Pre-Licensed Psychologist

Dr. Taylor Murphy is a pre-licensed clinical psychologist who specializes in forensic and psychological assessment. She is skilled in conducting assessments with children, adolescents, and adults, and she has extensive experience with various types of evaluations with those involved in the legal system. Following the completion of a forensic psychological evaluation, she provides expert witness testimony when needed.
Dr. Murphy is also skilled in providing individual psychotherapy with adults, typically using Acceptance and Commitment Therapy (ACT). From that orientation, clients learn to stop avoiding, denying and struggling with their inner emotions and, instead, accept that these deeper feelings are appropriate responses to certain situations. Thus, Dr. Murphy helps clients create a rich and meaningful life, while accepting the pain that inevitably comes with it. Dr. Murphy is dedicated to helping others and strives to cultivate and genuine connection with her clients.
Dr. Murphy earned a Bachelor of Science degree in Psychology from Lebanon Valley College in Annville, PA. She chose to complete her graduate studies at Widener University in Chester, PA, where she earned a Master’s Degree as well as a Doctorate in Clinical Psychology. She completed a concentration in Forensics and wrote her dissertation on incorporating a personality measure into a risk model for male inmates.
Dr. Murphy spends most of her free time with her spouse and golden retriever, though she also enjoys reading, watching and playing sports, spending time with family and friends, and true crime.

clinical practice

In his private practice, Dr. Gransee focuses on providing his unique brand of therapeutic intervention, involving a combination of insight-oriented and solution-focused treatment. The goal is to support the individual in becoming the best version of themselves they can be, through increased awareness of problem areas, and improved confidence in the ability to become the best that they can be. Depression, anxiety, anger, and other emotional or behavioral issues are viewed as evidence that the individual is overwhelmed/agitated by their life choices, and not as permanent conditions that are not able to be corrected.
