Mary Lou Macilvaine, PhD provides clinical child and adolescent psychology services from 4313 Ridgeway Drive in Kensington, San Diego, within the 92116 ZIP. Her practice, incorporated in 2008 under NPI 1083879506, focuses on developmental and behavioral assessment for children and adolescents alongside health psychology for patients across the lifespan. Ridgeway Drive sits in the residential core of Kensington, east of Adams Avenue and within walking distance of Ward Canyon Park, where the neighborhood's family-oriented character shapes much of the referral base. Pediatric evaluations cover anxiety, depression, behavioral disorders, trauma response, and adjustment difficulties that surface during school transitions, family disruption, or developmental milestones. Families coordinating dental care for children with anxiety or sensory sensitivities often work across providers, and Kensington Pediatric Dentistry and Orthodontics shares the same pediatric-age population along the Adams Avenue healthcare corridor. Dr. Macilvaine's health psychology training extends her scope beyond childhood behavioral work to include psychosomatic illness assessment, chronic health condition adjustment, and the cognitive-emotional factors that influence recovery and treatment compliance in adult patients. The Kensington practice draws referrals from Normal Heights, University Heights, and the adjacent North Park neighborhoods connected by Adams Avenue and 30th Street. Vision-related learning difficulties in school-age children occasionally require coordinated evaluation between psychology and optometry, a workflow that involves practices such as Heights Optometry when developmental screening suggests a visual processing component. Dr. Macilvaine's dual specialization in clinical child psychology and health psychology positions the practice to treat the full developmental arc from early childhood behavior intervention through adolescent identity formation and family systems work.
