I first met Gillian during a leadership conference, and her energy and presence immediately drew me to stay connected with her beyond the event. Gillian has an incredible gift for listening deeply and guiding people to view challenges from different perspectives, helping you uncover the best solution for your own situation. Her compassionate and caring nature makes her not just an excellent coach, but also a true mentor. She supported and guided me through the lowest point of my career, helping me regain clarity and confidence, and ultimately make a decision I have never regretted. If you’re facing roadblocks, or even just a mental block, I can confidently say that speaking with Gillian will make a real difference.

I had the privilege of being mentored by Gillian Tan from March to May 2025, and the experience was nothing short of transformative. Gillian stands out as a mentor who blends strategic intelligence with deep empathy. A rare combination that makes her guidance both practical and inspiring. She doesn’t simply offer solutions; instead, she listens intently, asks insightful questions, and challenges you to think beyond your comfort zone. Her approach helps you uncover your own strengths and see new possibilities you may have overlooked. Every interaction with Gillian was marked by authenticity, generosity, and care. She has a unique ability to make you feel supported while still holding you accountable for your growth. Her wisdom extends beyond professional advice. She guides you to develop the mindset, confidence, and clarity needed to lead effectively and sustainably. What began as a structured mentorship quickly evolved into a trusted relationship built on mutual respect and genuine connection. Gillian’s ability to balance compassion with strategic thinking makes her an extraordinary mentor and role model. I am deeply grateful for her guidance and the lasting impact she’s made on both my career and personal development. Anyone fortunate enough to learn from her will gain lifelong value.

I am truly honoured to give this testimonial for Gillian - my ex-colleague, good friend and now, I respect her as my mentor. We were colleagues of Huhtamaki in the past. Gillian has been promoted a few times within the company from handling key and task jobs such as Marketing, Quality Control, Production Planning to managing company Global Key Customer Account. I have also witnessed her constant effort to improve herself during her career path despite her heavy workload. Even though our careers have taken different paths, whenever I have encountered problems, I always seek her advice. No matter how busy she is, she always finds time to teach and guide me without fail. I am deeply grateful for that. Gillian is a selfless, generous and magnanimous person. Gillian shared with me that her aspiration is to coach others to be the best versions of themselves. I fully trust that Gillian will continue to lead and inspire the younger generation, even my children, with the same care and dedication.

Every conversation with Gillian feels like sunlight streaming gently through the leaves. The warmth and calm in our exchanges naturally create a space where I can rest into trust and openness. Within this atmosphere, I feel the soft embrace of nurturing care, and at the same time the steady presence of a tree trunk—grounded, strong, and reliable. Like a true friend, she accompanies me with patience, compassion, and authenticity. Meeting such a companion is a gift on my journey, reminding me that deep connection and genuine encounters can indeed last and sustain.
