KW Agent Ania Gueffroy
Ania Gueffroy | Productivity Coach
With more than 19 years in the real estate game, I have come to specialise in the development and management of new developments. Working with developers such as Grosvener International Property Services, founded in the United Kingdom, I have built up the reputation for ensuring a sold development. I have dealt with and have experience in dealing with all stages of a new development, from the initial planning to the marketing, as well as town planning. I joined the amazing KW Clockwork team as their Team Leader in 2018, where I worked to train and grow the agents under me to become Millionaire Real Estate Agents. In April 2021, I moved positions to become the Productivity Coach, and I've never felt happier! I get to see the agents grow through my training and one-on-ones. To have a direct influence over someone's growth and watching them achieve their goals is the reason why I love what I do. My training motto is ‘actions speak louder than words’, meaning that there is no better way to train someone than to show them how it is done. Allowing the agent to join me in appointments so they can watch and learn how to get the signature.
