Welcome! My name is Tracy Marsh (she/her), and I’m so glad you found your way to Prosper. I’m a licensed psychologist in California with a doctorate in counseling psychology, and I bring over 25 years of experience in higher education as a university faculty member. I specialize in psychological assessment for a wide range of neurodiverse clients. I understand that taking this step can feel exciting and uncertain, and I’m here to provide a warm, supportive environment where we can explore your unique strengths and needs together.

Hi there! My name is Dr. Lauren Dreisch and I am a Licensed Psychologist in the state of Florida. I was born and raised in Miami, FL and completed my undergraduate and graduate studies at the University of Florida in Gainesville. I returned to South Florida and completed my internship at Nova Southeastern University in Fort Lauderdale and my fellowship at Nicklaus Children's Hospital in Miami, where I currently live! During my undergraduate studies, I also received a minor in Disabilities in Society and I consider myself to be a disability advocate. I love what I do because through assessment I am able to help people better understand their unique set of strengths and difficulties.

Welcome! I’m so glad you’ve found your way here! My name is Erin Henderson, and I'm a licensed psychologist based in Pittsburgh, Pennsylvania. I am licensed in both Pennsylvania and New York, and through Psypact authorization I’m able to work with clients across 42 states. My approach is rooted in a deep belief in understanding the unique experiences of each person I work with. Having the privilege to support individuals as they explore and make sense of their neurodiversity is truly inspiring. My goal is to create a compassionate and nonjudgmental space where you can feel comfortable, validated, and understood as we work together to navigate the complexities of adult autism. I believe that everyone deserves the opportunity to thrive and live authentically, and I’m committed to helping you uncover your strengths and embrace your full potential.
