Cherie earned her master’s degree in counseling psychology from National University and completed her intern hours working with adolescents in foster care and adults with severe mental illness in community-based programs. Over the past four years, she has focused on mental and behavioral health in a telehealth setting, treating lower-acuity concerns such as anxiety, depression, panic, and adjustment disorders, along with trauma work using EMDR.

Her work emphasizes identifying barriers to success and examining unhelpful core beliefs, allowing patients to move toward meaningful and sustainable change.

Cherie spends the first one to two sessions gaining a clear understanding of where patients are coming from and where they would like to go. From there, she collaborates with patients to develop individualized goals, revisiting and refining them over time to support clarity, growth, and progress throughout therapy.
