John C. Parker IV Inc. maintains a clinical psychology practice in San Carlos, San Diego, at 6280 Jackson Drive, Suite 7, operating under California psychology license PSY5717. The practice was incorporated in January 1979, giving Parker more than four decades of continuous operation at the Jackson Drive location in the 92119 ZIP. Parker's NPI registration (1568580546) classifies the practice under taxonomy code 103TC0700X for clinical psychology, confirming an active provider record with the Centers for Medicare and Medicaid Services. The Jackson Drive office coordinates referrals with primary care physicians in the San Carlos corridor, including Center For Family Health on the same commercial strip. The office sits in the residential core of San Carlos, less than a mile from Lake Murray and the trail network that loops the reservoir. Parker's clinical psychology practice evaluates and treats patients through psychotherapy methods addressing depression, anxiety, stress, and behavioral health conditions that benefit from structured intervention. The practice provides wheelchair-accessible entrance, parking, and restroom facilities, and operates on an appointment-recommended basis. San Carlos draws its patient base from the neighborhoods between Navajo Road and Lake Murray Boulevard, and the Jackson Drive location serves the broader San Diego east county corridor including Del Cerro and the communities flanking Cowles Mountain. Vision-related cognitive changes and reading difficulties often surface during psychological assessment, and the optometric evaluations at Robert Gonzalez, OD in San Carlos provide the diagnostic baseline that informs treatment planning for clients presenting with attention and processing complaints. Parker's 1979 incorporation date makes the practice one of the longest-continuously-operating psychology offices in San Diego's eastern communities.
