Dr. Gillian Lockitch is an international speaker, author of Growing Older, Living Younger: The Science of Aging Gracefully and The Art of Retiring Comfortably, and host of the Growing Older, Living Younger Podcast. As a dual-certified Specialist in Paediatrics and Medical Biochemistry and Professor at the University of British Columbia, her professional career was rooted in science. During her rehabilitation from life-saving emergency spinal surgery, her passion to be able to dance again led her to explore the intersection of medical and epigenetic science with non-Western healing traditions, to understand how to change aging at the cellular level. Within the Growing Older, Living Younger Project, the Change Your Aging Masterplan cycle is a year-long 3 part coaching program to preserve mind and brain, build your best body, and to survive and thrive in your environment. At 70 Dr. Lockitch became a first time entrepreneur, building a global online business with the premiere wellness and beauty company, to help others extend their healthspan, stay vibrant, active, and independent as they age. Now retired from medical practice, Dr. Lockitch is an empathetic coach and mentor but does not diagnose, treat or prescribe for medical diseases.
