Robert Johnstone

Managing Director

Robert worked for many well known Retailers over the last 30 years including B&Q and Superdrug and more recently was  employed as the Operations Director for B&Q’s parent company Kingfisher in Russia. He wanted to open his own business and do something completely different. Robert’s wife and mother in law both worked in home care and he found himself being excited by the opportunity of setting up a new business where he could give something back to the community by looking after people in their own homes and giving them a better quality of life through a well trained and caring team of care assistants.

Tracey Johnstone


Working in care for several years and being passionate about delivering the best standards of professional care and support it made sense for Tracey and her husband to open a home care business where they can offer services to the local community. Given the growing need for home care Tracey is looking forward to ensuring the customers of Cambridge and South Cambridgeshire get the level of service they deserve.

Perpetua Tirivangani

Registered Care Manager

Perpetua has worked in care for more than 19 years, having come from a teaching background in Africa. She worked her way up the ranks from care assistant, to field care supervisor, to care coordinator, to deputy manager, then manager. Perpetua is passionate about the welfare of her staff, giving them what they need to enable them to do a good job and enjoy doing it. An example of this is her open-door policy which is good for both recruitment and retention of staff, something needed in the care sector right now.

Perpetua praises the teamwork and the positivity among staff both in the field and in the office. The positivity extends to our customers, who we endeavour to provide the highest quality of care for, always. I am looking forward to building even greater team rapport and to empowering my team to be the best they can be.
