Dialysis School of San Diego operates in Chula Vista along Bonita Road, providing the only Bureau for Private Postsecondary Education-approved hemodialysis technician training program at a private postsecondary institution in San Diego County. The five-month curriculum prepares students for State National Certification exams through hands-on clinical rotations, training graduates who enter the same renal care workforce that staffs facilities near Bonita's senior communities including Bonita Villa Senior Living on Sweetwater Road. Founded in 2011 by director Teresita Mabini and incorporated as City Healthcare Institute Inc., the school holds a BBB A+ accreditation and maintains current Student Tuition Recovery Fund assessments. Graduates qualify as Patient Care Technicians, Hemodialysis Technicians, or dialysis nurses, filling staffing pipelines across South Bay dialysis centers and home health agencies such as ComForCare Home Care that coordinate peritoneal dialysis support for homebound patients. Instruction covers arteriovenous fistula cannulation, dialyzer reprocessing, water-treatment system monitoring, and the electrolyte-balance protocols governed by California Code of Regulations Title 22 for dialysis facilities.
