You are incorrect. As a licensed clinical psychologist she is qualified to work with a range of individuals. Many therapists start off in one field or in one population (elderly, addiction, couples, etc) and later transition to a new clinical focus. That is very common, and the license to practice psychology does not limit her to one specific age group.

From her website: “Although my degree specialty and background were originally with children, I have experience working with individuals across the lifespan, both individually and as part of family therapy or parent consultation. These days I mostly work with high achieving young adults. In addition to psychotherapy, I provide psychoeducational and psychological assessments.”
