Registered with Medicare PECOS as a clinical psychologist in Hillcrest's 92103, Carlos Nelson PhD operates a solo therapy practice at 211 West Robinson Avenue just off Fifth. The office handles adult individual psychotherapy in a solo-practitioner format, contrasting with the multi-provider intake system used at San Diego Psychology Center a few blocks north. Sessions are arranged directly by phone and the practice does not maintain a public website, keeping the clinical footprint intentionally small. Complex diagnostic questions requiring full psychological testing batteries beyond the scope of a solo office are typically directed to multi-psychologist groups including Inspired Psychology. Ongoing long-term depth psychotherapy for established adult patients with recurrent depression or chronic adjustment difficulties forms the core of the caseload.
