Dr. Stacy Johnston operates a clinical psychology and divorce mediation practice in La Mesa's Casa de Oro area at 4730 Palm Avenue, combining psychological assessment with structured mediation for couples navigating child custody, asset division, and living arrangements. The mediation model applies clinical training in family dynamics to settlement negotiations, addressing the stress-related health impacts — including bruxism and jaw tension — that often prompt concurrent referrals to dental providers such as Affinity Dental of La Mesa. California psychology license PSY17457 has been active since the practice's 2001 founding, and Dr. Johnston is affiliated with Southern California Psychology Centers APC. Family therapy cases involving elderly dependents or multigenerational caregiving disputes often require coordination with in-home support agencies like Golden Care to assess the care environment as part of custody or guardianship evaluations. Highest-complexity mediations involve multi-party custody arrangements requiring forensic psychological evaluation, parental fitness assessment protocols, and structured co-parenting plan development with behavioral-health benchmarks tied to court-ordered review timelines.
