What our customers are saying

"Karin at Multiplicity offers a wide range of services and is always helpful, efficient and informative. We have used Multiplicity for drop-off/pick-up at the airport, pet-care while away on holiday and for French tuition, and would highly recommend it to anyone needing some assistance at the busiest times."

Abigail, mother of 3

"As a busy Executive it can be a challenge to maintain a balanced and full life. With all the constraints and random daily tasks that need to be taken care of Multiplicity has been an extremely valuable service! I've tried other concierge services and they were over-priced and not as personal. Multiplicity is fairly priced, trustworthy, personal and flexible. I could not imagine life without them now!"

Craig, Corporate MIS/IT Director

"Karin has been a tremendous help to me. Taking on a whole range of tasks so that I am free to focus on my business. She is very reliable and well organised."

Peter, Investment Manager
