Irene Sim, Office Administrator

Irene brings over 25 years of medical administrative experience, including human resources management and general administrative support to patients, staff, and management. Before coming to Whitby Massage Therapy & Wellness, she was an Office Administrator for Whitby pt Health, as well as an Office Manager for the Whitby Medical Centre. Her appreciation for naturopathic medicine started when one of her daughters became very sick and medical doctors could not provide any answers or relief. A family friend referred her to a Naturopathic Doctor and it was only then that, through natural supplements, diet restrictions, and lifestyle changes, Irene and her daughter began to see results. Natural solutions have been a critical part of Irene’s family ever since.

Irene has been a Whitby resident for her entire life, raising three children in the community. She holds a Bachelors degree in Psychology and enjoys sharing meals and get togethers with family and her two puppies, Mickey and Simba.
