Donald G. Gerken, DC, DACCP, CSTD in Chula Vista's Eastlake area is the only South San Diego chiropractor holding diplomate-level certifications in both pediatric chiropractic and CranioSacral Therapy from the ICPA and Upledger Institute. The DACCP credential certifies expertise in birth-trauma resolution, tongue-tie assessment, and colic management — conditions where cranial-nerve dysfunction may also warrant evaluation by ENT Associates of San Diego for persistent ear or airway symptoms. CranioSacral Therapy Diplomate status designates advanced training in the rhythmic palpation of craniosacral fluid dynamics, applied to infants, pregnant patients, and adults with migraine or sensory-processing concerns. Established at 861 Harold Place since 1996, the practice maintains digital X-ray capability on site and coordinates complex pediatric gross-motor cases with Performance Plus Physical Therapy - Otay Ranch for developmental-milestone rehabilitation. Highest-complexity CranioSacral sessions involve five-gram-pressure cranial-vault holds targeting sphenobasilar synchondrosis restrictions in neonates presenting with asymmetric head shape or impaired latch reflex.
