Dr. Wilder is also experienced in conducting psychological assessment of autism, personality disorders, bipolar disorder trauma, depression, anxiety, obsessive-compulsive disorder, attention difficulties, learning concerns and more for children and adults. She understands the nuance of evaluating autism in girls and evaluating autism in adults, two populations who often go misdiagnosed due to adept masking behaviors.

She subsequently completed her post-doctoral training at Great Life Counseling Center in Dallas, TX. During her graduate school career, she completed her therapy training at a community mental health clinic and private practice and her assessment training at the University of California, Los Angeles where she was first trained to perform autism evaluations. In these settings, Dr. Wilder performed individual, couples, group and family therapy, and psychological and neurodevelopmental assessments.
