Christa Marshall, Psy.D.

I am a Licensed Clinical Psychologist with a doctoral degree in clinical psychology.  My practice is called Marshall Psychological Services, LLC and is located in Pittsford, New York.  I specialize in tailoring psychological treatment interventions to clients’ needs.

Much of my clinical experience was gained in community mental health (CMH) agencies and the Veterans Health Administration (VHA), giving me particular expertise in mood and anxiety disorders, as well as posttraumatic stress disorder (PTSD).  As a result of my experience in CMH and the VHA, I have worked extensively with individuals and families adjusting to serious medical conditions, including traumatic brain injury (TBI), dementia, spinal cord injury, amputation, chronic pain, and sensory deficits (i.e., hearing and vision loss).

I also have a special interest in working with pregnant and postpartum women, as well as individuals experiencing pregnancy/infant loss. In March 2018 I was a guest on Richmond’s The Next Tuesday Podcast, where I enjoyed talking about postpartum life and career with hosts Caroline and Susan.

In addition to my clinical work, I also worked as an adjunct professor at Roosevelt University in Chicago, Illinois, teaching psychology courses to both undergraduate and graduate students.  Courses have included abnormal psychology, human sexuality, human motivation, research methods, child abuse and family violence, and basic clinical skills.  I have published and presented research on best practices for teaching psychology in higher education, PTSD, TBI, and delivering mental health services via telehealth.

Before studying clinical psychology, I worked for an organization called Reachout of St. Lawrence County, a local crisis hotline serving this rural, New York community.  This afforded excellent experience in crisis assessment, management, intervention, and referral.  In addition, I also volunteered with a local organization that provided crisis intervention services to survivors of rape and sexual assault within this same community.
