"I worked under Crispin for 7 months while at Ria Financial in his Compliance team. As a law student in my final year of study. Crispin willingly became a mentor to me making the final stage of my 5 year degree a more clear and directed time. Crispin coached and developed me in the areas of AML/CTF, fraud and sanctions. He walked me through technical concepts and risk management with real life examples. As a manager Crispin was understanding and empathetic - he had an open door policy and encouraged me to share with him any concerns or questions I had. We would also often brainstorm together as to potential directions for my future career, encouraging me to keep an open mind and helping me see the near infinite possibilities and avenues open to me. I am extremely thankful for Crispin's advice and guidance over those months with which I have grown to both skill and personally."

"I worked with Crispin Yuen at AMP during 2021. Crispin and I were in Group Risk Management, although our roles differed. My role was focused on Group reporting and Crispin was supporting the Anti-Money Laundering team. I was able to observe Crispin's professionalism and reliability in dealing with multiple stakeholders. Crispin's polite and friendly nature had a very positive impact on those around him and he added to a strong sense of team culture. Crispin's strong communication skills and proactive nature ensured the project status and any issues were adequately communicated and resolved and his technical knowledge ensured the desired outcomes were achieved. Crispin's ability to work independently was also a key strength in the consultant role he performed at AMP. I am happy to recommend Crispin Yuen and would see him as an asset to any organisation."
