Working with JD has been a transformative experience for my growth as a leader and advancing my overall business acumen. Under JD's mentorship, I developed a stronger sense of direction, confidence in my decision-making, and a deeper understanding of fostering innovation and drive in my teams. JD's impact on my career has been profound. His ability to dissect complex business challenges and provide actionable advice is unparalleled. His approaches have significantly improved my operational efficiency and ability to drive employee satisfaction. His unique blend of analytical rigor and genuine concern for the people he works with sets JD apart. His approach to leadership and management is about meeting business goals and growing and nurturing the team to reach its full potential. I would unequivocally recommend JD Deitch to other leaders. His insights and guidance are invaluable, not just for navigating current challenges but also for preparing to meet future demands.

JD is someone I have grown to respect and confide in, having initially had the opportunity to work alongside him as an operator in the field. JD is an excellent critical thinker and very strategic in his approach. As a leader, his style is to help shape a strategic operating framework with clear objectives and desired outcomes, then to empower his team with a good degree of autonomy and back them with unyielding conviction and support. JD is a very capable coach and mentor, but equally as comfortable in the weeds contributing directly to projects and assignments. JD doesn't pull any punches and isn't obsessed in winning popularity contests and vanity recognition. Instead he focuses on continuous improvement and sets a high bar in doing so, while putting the emphasis on teamwork and enabling individuals. JD has an ability to cut through a lot of BS and get to the heart of problems, help unpick them, and drive winning strategies and behaviours for the benefit of all stakeholders. As a result of seeing JD's work, you get a sense of what best practice looks like in many operational disciplines, coupled with a sharp focus on high-performance and accountability. JD's operational experience and executive leadership skills will be a benefit to any team and set of shareholders.

I've known JD for almost a decade now, as both a client and a friend. He was my contact at one of early clients - that's when we first got to work together. Since then, I've followed the progression of his career and we talk several times every year. And during those calls, we talked about his work with those companies. Our relationship has given me a ring-side seat to watch him lead, manage and work. And I can say, unequivocally, he is one of the best 'thinkers' I've ever known when it comes to organizational effectiveness, leadership and company culture. He 'gets' what needs to be done and knows how to go about making it happen. If you're in an organization that needs some help at the highest levels, do yourself a favor and reach out to JD... it's a decision that will pay dividends for a long time to come.

JD is not only a leader but also an “empowerer”. Working as part of JD’s people org, I was fortunate to work on various projects that would not have been feasible a few years prior. JD provided the tools, resources, and support to overcome any barriers and roadblocks. He empowered me to make judgement calls when appropriate which had let me grow exponentially as a professional. I am grateful to have had JD as a leader!

Director of Operations at ARP Insights
I worked with JD for more than 6 years across multiple departments such as Project Management, Operations, and Human Resources. One thing you need to know about JD is that he is the person you want on your team when facing any issue, whether it's a small team management issue or whole company heading in the wrong direction. Each time the top management struggled to get things done, JD was appointed to head that department. Within months, we could see quantifiable positive changes in all aspects: revenue, quality of work, accountability, and team behaviors. He is one of the few leaders I have seen who actually listens to his team's suggestions and incorporates them into the company's vision in a way that benefits everyone. Being accountable for all you do in life, showing resilience during challenging times, and striving to improve by 1% every day are some of the major qualities I learned from JD's leadership during my professional life.

I had the privilege of working with JD on my leadership growth from late 2020 through 2021. JD helped me navigate various business challenges, big and small, always encouraging me to be prepared and think strategically. His guidance on team planning, managing growth, and balancing tactical and strategic work has been invaluable. JD's approach to leadership is both inspiring and highly practical. He emphasizes the importance of execution and preparation. His insights into vision, people, structure, and communication have positively impacted my leadership style. JD, thank you for your support and wisdom. I highly recommend your leadership coaching to anyone looking to elevate their career.

I've had the privilege of working under the leadership of JD Deitch, whose influence on my career and personal growth has been truly transformative. JD's approach to leadership has not only pushed me out of my comfort zone but also placed me in roles and situations that I would of previously shied away from. This experience has helped me grow immensely, both professionally and personally. JD's impact on my career has been profound. He emphasized the importance of striving for incremental growth daily, a strategy that's become a key part of how I approach my work now. Under JD's guidance, I've learned to view success as a process of continuous improvement, always striving to be a bit better than I was yesterday. What really sets JD apart is his empathetic and adaptable approach to leadership. He holds himself to high standards of accountability and encourages the same level of discipline in those he leads. JD's ability to provide feedback and advice that’s tailored to each person's needs makes his guidance not only effective but truly supportive. I would highly recommend JD to any leader looking to enhance their leadership skills. JD's real strength lies in his mentoring and coaching abilities, along with his genuine and flexible way of leading. This combination gives you truly useful insights into how to lead effectively.

Director of Operations at Cint
I have known JD for more than 4 years and I have always been impressed with his people management skills. I have worked with some awesome leaders in the past, but JD is right at the top. When it comes to valuing his team members, there is no one like JD. I still remember when he was the Chief Operating Officer at Cint, how he used to mentor and motivate us to be better at things we do. He never forgot to mention his team members’ achievements in company All Hands meetings, which was so motivating. During the time of COVID-19, companies started laying off their employees, JD as a COO of Cint approved a COVID bonus for us. That was the time when I was most impressed by his leadership skills and that gesture showed how much he cared for his team. When you value your team members, they will give their best for you. That’s what I learned from him. And this has helped me immensely in my career. Thank you, JD for everything you did for me. You’re a great leader and an even better human being.

I worked with JD for about 12 months (late 2021 - late 2022) through the closing of a transaction, across the value creation and realising synergies as well as supporting BAU operations. One of the behaviours I have observed, and influenced how I approach business issues, is the focus and vision applied in a specific area which yields extraordinary results. JD's approach to leadership is unique in the way he develops strong interpersonal relationships with his team and invest time to ensure a high performing environment which enables people to thrive. I would love the opportunity to work with JD again in the future!

JD Deitch is an amazing leader, mentor and coach and his many years of experience in a variety of different leadership roles shows up in the posts and videos that he creates JD Deitch has helped me in many ways to be a better leader in my role at Cint. Working under his great leadership has always empowered me to perform independently as he always gives his team(s) the confidence to perform without intervening many times and also provides all the needed support and guidance at the same time. This is in fact the most valuable leadership quality that I find in JD Deitch I would certainly recommend JD Deitch to other new leaders to learn the best skills of leading large teams in diverse and ever-changing situations in companies Thank you JD Deitch for all the great advice and suggestions - wishing you continued success

I had the privilege of being a part of JD's team from my P2Sample days. A keen listener, strategist and a leader par excellence, JD brings method midst chaos. The systems and processes that he set-up in Operations and Quality domains during the P2Sample tenure, and thereafter when P2Sample was acquired by Cint, were absolutely phenomenal. It was intriguing to me as to how the processes that JD actioned were so well-rooted and executed among hundreds of employees spanning multiple geographies and cultures! What's more, the processes that he conceptualized and put into place then are effective to this day! JD also has a very good knack of identifying the "right people for the right job" - he identifies leaders and gives them a free hand to run the show. I have had the opportunity of working with leaders that he groomed, and they're thorough professionals when it comes to their respective domain expertise and areas. A strong advocate for Quality improvement in market research, JD led the way at P2Sample, and then Cint, towards improvisation of Quality across the industry through his detailed reports on Quality and fighting fraud, as also mobilizing people across the market research space towards the Quality cause. Personally, I have learnt a lot from JD's leadership style: meticulous, inspiring, objective and data-oriented, empathetic, supportive, a keen listener and a great presenter, process architect, ideator and a mentor who prepares leaders for the future! It was an absolute pleasure and privilege to work with such a genius, and given an opportunity, I would love to be a member of his team again!

I have had the privilege of working under JD's leadership for nearly seven years, though not as a direct report. Nevertheless, his impact on me has been profound. Throughout these years, I discovered that JD possesses a unique ability to discern what works and what doesn't—not just for the business, but also for the people. His vision encompasses both short-term and long-term objectives. His clarity of purpose and goals, combined with his ability to divide, analyze and clearly articulate individual components of a situation, truly sets him apart. I have always been somewhat hesitant about taking on a leadership role myself due to the significant challenges it entails. However, simply by observing JD, I realized that effective leadership is about leading by example in challenges, celebrating in triumph, standing by others in adversity, and inspiring through resilience. I hope all leaders have the opportunity to work with JD—not just work with him, but also to learn from him and, beyond learning, to be inspired by him.
