Doctoral-level psychology practice at 4065 Third Ave Suite 2132 places Sheila Gleason inside the medical office cluster directly facing the Scripps Mercy Hospital campus in Hillcrest. The clinical focus runs through adult depression, sleep disturbance, and chronic stress and anxiety presentations, an outpatient talk-therapy lane that overlaps with the doctoral-level work of peers including Carren J. Stika, PhD elsewhere in the same medical row. Insomnia layered onto mood disorders forms a recurring referral lane from primary care offices in the surrounding hospital footprint, where sleep-restriction protocols and behavioral activation must be sequenced before any pharmacology trial becomes the next step. Caseload overflow and second-opinion requests route to peer psychologists in adjacent Hillcrest medical buildings including Cassady Cindy PHD, since the Third Avenue corridor concentrates a dense cluster of doctoral-level mental health offices within a two-block radius. The most demanding referrals involve patients whose chronic insomnia is layered onto recurrent major depression, where the treatment plan must coordinate sleep-architecture work and depressive cognitions across months of session-by-session sequencing.
