Sheryl Crotta is a graduate of the 5 year program at the Canadian Academy of Osteopathy and Holistic Health Sciences, Hamilton, Ontario (2011). She has earned the Master In Osteopathic Manipulative Sciences (M.OMSc.) diploma. Sheryl is also a professional member of the Ontario Osteopathic Association.

In clinical practice, she brings her understanding of the structural and functional relationships of the body by thorough assessment and appropriate treatment. Treatment goals are for preventative care, corrective adjustment that focuses on the source of the problem or in some cases palliative care where relief is a welcomed option. Treatment is the application of gentle manual techniques that are highly therapeutic that focus on finding and correcting the challenges of the body systems.
