I initially thought Dr. Cassandra was a good listener who made me feel heard, but after my first appointment she did not follow up with prescription info and assessments and after my second appointment that lasted 10 minutes, I never heard from her again regarding a treatment referral that she said she’d make. It felt unprofessional and a bit negligent.
