Geof Tibbs, CO, CPA

Cranial Remolding Specialist


Geof possesses the cranial remolding knowledge and expertise that parents and providers can trust. He has nearly a decade of cranial experience and has treated over 1500 patients. Conditions treated include synostotic plagiocephaly of varied presentation and deformational plagiocephaly and brachycephaly. Geof works with each patient to provide an appropriate treatment plan based on patient age, presentation, referral source expectation, and family feedback. This sometimes means that no helmet is recommended or necessary for appropriate correction of the deformational head shape. Geof is also an advocate of home-based therapies to correct the head shape, in conjunction with and/or instead of treatment with a helmet, including repositioning programs, physical therapy, chiropractic care, and use of the Perfect Noggin sleep positioning system. Outside of the office, Geof enjoys spending his free time with his family- Wife Jessy, twin sons Arlo and Bodie, and dogs Lola and Kira.
