Jerry is a founding partner of Oak and Star Coaching LLP, an astrologer and a coach, who works with clients to achieve deep transformation through self-awareness and self-acceptance, and live a life of fulfilment. 

He believes that the outward manifestation of a fulfilling life begins on the inside, within ourselves. Guided by astrology and combined with Co-Active coaching, Jerry helps clients see their quirks as strengths, gain clarity on their internal tensions and triggers, and learn ways to achieve balance - emotionally and energetically. With a conscious and empowered inner self, clients can make better decisions and be more resilient to unexpected events as they step toward their goals and visions. 

Jerry studied Information and Computer Engineering at the University of Cambridge as a scholar with the Defence Science and Technology Agency. Upon graduation, he worked as a software developer at the Centre for Strategic Infocomm Technologies before going on to lead his own team of developers. 

To enhance his leadership skills, Jerry underwent the coach training program offered by the Co-Active Training Institute (CTI), followed by their 10-month Leadership program, both of which turned out to be life-changing experiences. The skills he picked up enabled him to plan and facilitate a company retreat with over 100 senior leaders. He then went on to conduct workshops on emotional intelligence with top organizations in the hospitality and humanitarian sectors.

Jerry now supports his clients on their own journey of transformation and fulfillment, through building awareness and living life from a balanced and empowered place.
