Christina Biedermann, PsyD
Senior Clinical Psychologist
Dr. Christina Biedermann is a board certified, licensed clinical psychologist with over 15 years of experience in the assessment and treatment of adolescents, adults, couples, and families. She has expertise in working intensively with complex patients and families for whom other treatments have been ineffective. Her patients often have complicated personal and family histories that have contributed to unsatisfying ways of living and working, and, sometimes, to the development of multiple psychiatric diagnoses, including complex trauma.
Dr. Biedermann is board certified in Assessment Psychology and has extensive experience working in schools, the juvenile justice and child welfare systems, outpatient settings, and hospitals. She provides psychotherapy for individuals, couples, and families, as well as parenting education and psychological assessment for treatment planning, the assessment of therapeutic impasse and suicidality, and custody evaluations. In addition, she provides consultation services, including carefully vetted referrals, care coordination with multiple treatment providers, facilities, and disciplines, and psychoeducational services, to individuals and families who have complex mental health and substance abuse treatment needs. Through her work, Dr. Biedermann has found that insight into one’s characteristic patterns of managing stress and relationships, in addition to developing new skills in these domains, most often yields meaningful and sustained change.

Dr. Biedermann enjoys teaching and supervising psychological assessment, psychotherapy, and clinical writing.
