Senior Manager - Global Property Taxes at Magna International

Mary is one of the best professionals I’ve worked with. She is intelligent, hardworking and forward thinking. Her maturity and in-depth knowledge of their business made the project highly successful. As the Project Manager/Sponsor she knew exactly what was required and how they needed to be phased out to achieve the project goals. I’m sure she will apply the same professionalism, commitment and maturity in all her endeavors. It was my pleasure working with her on their project. Wishing her all the very best!!

Mary worked with me in INVESCO Asset Management for a number of years and her professionalism, dedication and allround performance was top quality. Mary works really well within a team environment and can also manage a team to achieve their goals. I would highly recommend her to any employer.

Andy Barry, 

Head of Traditional Fund Services Operations at JP Morgan

Mary came into an incredible mess. She took it on and solved the problem. Her real strengths are her skills to sort things out & the inclusion of people involved. She was superb, very easy to work well with. She continuously gave us an update. Mary could get her head around the various product lines very easily, which is a huge asset. She was instrumental in getting our inventory system bar-coded. She was also part of our recruitment drive to hire an operations manager to get our company onto the next level. I always felt we were on the same wave-length. She solved problems before they became problems. Her ability to juggle all the balls in the air and do a really good job is incredible! Mary also helped us get together a business plan for funding from the Irish Tourist Board. She has a lot more than accounting to offer. She is like a ’sponge’ on getting information.

I am very grateful for my LEO mentor. Mary Hayden really applied herself to understanding the different strands of my business and skill set and helped me adjust my business plan, network effectively and look at new income streams. She is so good at business systems and organization that she inspired confidence to actively build the business and diversify rather than just cope with what was left after the lock down. What a valuable skill. Mary in particular made the difference between it being a time of crisis and instead it being a time of hard but creative work, set to key milestones and incredibly helpful feedback of each productive session.

Mary Hayden is a person you can trust with your business. Super professional, wise beyond her years with phenomenal attention to detail. Her new book “From the Ground Up” is a masterclass in the foundations of a successful business, and like Mary, the advice is practical, measured and well researched. The book takes a no-nonsense look at the ten building blocks to business success. Unlike many books of this genre, Mary’s writing style is relatable, easy to distil and put into practice. If you are in business or thinking of getting into business and want guidance from tried, trusted and tested business leaders, Mary should be top of your list. As a person and as a professional, I cannot recommend her highly enough.

I first met Mary Hayden in late 2019 when she was considering a career change and was immediately impressed by her business knowledge and her passion for helping business owners. She has a unique combination of skills combining her finance qualification with a process-driven approach underpinned by her six sigma qualification. This approach allows her to look at a business end to end and figuring out efficient and effective solutions that contribute significantly to the bottom line. All of the Agile clients that Mary has worked with since she started working with us in April 2020 have been hugely impressed by her enthusiasm and practical solutions. She has been great to work with and continues to make a significant contribution to The Agile Executive.

Tony Dignam,

CEO of The Agile Executive

Mary Hayden made a significant difference to our business. Some tasks, such as application for R&D Tax exemption was a daunting task for us. Mary put us in the right direction. 

I found the whole experience very rewarding from both a business and personal level, and I put this down mainly to Mary Hayden and how she approached the sessions.

SFA/Skillnet Mentors work Program

Mary joined us under the mentors work via the Agile Executive, a super company that facilitated the programme. Still, Mary has stayed to become our part-time CFO and has made a considerable change to how we grow our business as a growing SME. Having a transparent view of all things financial and knowing that VAT, PRSI Grants and supports are clean is imperative as we employ more staff and invest in growth. Mary focuses on cash flow and is a sales orientated finance professional who wants to understand the business and see it grow safely and sustainably. I can recommend Mary’s persistence and attention to detail for any business that needs to control their finance.
