Tamar Krebs

Founder & Executive Director

Tamar Krebs is obsessed with doing dementia differently. In 2011, Tamar founded Group Homes Australia, an innovative dementia and ageing small scale model. She attended 62 meetings, did 38 presentations, and was rejected 37 times before she found the right people to support her vision 

For the past 24 years, Tamar, Registered Nurse holds qualifications such as Master of Health Service Management, Bachelor of Science, and various certificates in the study of Gerontology. She is recognised as a person that understands the human needs of those living beyond a diagnosis of dementia. Tamar is a sought-out keynote speaker, panellist, and media commentator. In 2021, Tamar Krebs moved from Co-CEO of Group Homes Australia to executive director with a continued focus on disrupting the industry of dementia care, workforce, and innovation to ensure even more lives can flourish.

Jonathan Gavshon

CEO

Jonathan has a background in Business and Finance. Dementia and the aged care sector are also very close to his heart, having had a grandfather pass away from the disease. He has studied and worked overseas and in Australia.

Prior to joining Group Homes Australia he worked at The Optical Company, a network of 30 glasses stores focusing on business development. Prior to that he worked at Allegro Private Equity, working alongside the CEO on the national rollout of a network of 50 mother and baby stores. He co-founded a start-up called Twobirds Bridesmaid, a retailer and wholesaler of bridal wear. From 2000-2007, he lived in New York where he was Vice President of J.P. Morgan’s Equity Capital Markets division. He is also passionate about the broader community, having founded The Observership Program, a not-for-profit focused on the leadership and development of young professionals. He has an undergraduate degree in Commerce and Masters degree in Business Administration.

Jonathan is married to Daniella and has three children, who you may see around the homes…. they love to socialise!
