Trinity Alexander, Ph.D., Psychologist in Haverford, Pennsylvania

Helping children, adolescents, teens, adults, and older adults gain clarity about their cognitive, emotional, and behavioral health is at the heart of Trinity Alexander’s work at LifeStance Health. She provides comprehensive psychological testing and evaluation services for patients throughout Pennsylvania, helping individuals and families better understand challenges that may be affecting school performance, daily functioning, relationships, and overall well-being. Through a thoughtful and evidence-based approach, Trinity works to identify strengths as well as areas where additional support may be beneficial. As a psychologist, Trinity specializes in psychological testing and neuropsychological testing, using clinically validated assessment tools to provide meaningful diagnostic insights. She evaluates concerns related to ADHD, anxiety, and childhood behavior issues while also addressing a broad range of additional mental health and developmental conditions. Her goal is to translate complex assessment findings into practical recommendations that help patients, families, and treatment providers make informed decisions about care. Trinity is particularly passionate about helping individuals obtain a deeper understanding of themselves through the assessment process. She recognizes that receiving answers to long-standing questions can be life-changing, whether a patient is struggling with attention difficulties, emotional challenges, learning concerns, or behavioral issues. She strives to create an assessment experience that is collaborative, supportive, and tailored to each person’s unique circumstances. In addition to her primary areas of expertise, Trinity has experience evaluating and supporting individuals with depression, PTSD and trauma-related concerns, and obsessive-compulsive disorder, as well as other mental health conditions. She also has experience working with members of the LGBTQ+ community, individuals with autism spectrum disorders, those with developmental disabilities, children involved in adoption or foster care, first responders, and other diverse populations seeking diagnostic clarity and treatment guidance. Trinity earned her education through West Virginia University and American University. Since beginning her clinical practice in 2013, she has remained committed to ongoing professional growth and delivering high-quality psychological assessment services grounded in current research and best practices. Outside of her professional work, Trinity enjoys reading Stephen King novels, playing retro video games, hiking, exploring caves and natural wonders, learning about new subjects, enjoying trivia, experiencing different cultures, and trying new foods. She especially values opportunities to share these experiences with family, friends, and new people she meets along the way.
