  • Mark
    Management

    Mark

    Managing Director

    I started working here in January 2017 when I founded the company. My role involves balancing the needs of the practice with hands-on work with clients. My focus is on ensuring that the business delivers the highest standards and continues to grow. With clients, I typically assist businesses in improving performance, preparing for a sale, or managing succession planning.

    I passed the AAT examinations in 2003 and have 23 years of experience in practice, with over 15 years at a senior level.

    I enjoy being part of an amazing team that has quickly grown into a multi-site accountancy practice. Outside of work, I spend time with my wife and children, watch Liverpool and Scunthorpe United, and occasionally play the guitar, reliving a past life.

  • Harry
    Management

    Harry

    Regional Director · Retford

    I began working here as a work experience student in July 2017 before officially starting my apprenticeship in September 2017. Since then, I have completed both my AAT and ACCA qualifications, becoming a Chartered Accountant.

    My role involves managing the Retford office and team, while maintaining a hands-on approach with clients. I work closely with clients to provide up-to-date advice, support their business needs and identify opportunities for effective planning and growth.

    Outside of work, I enjoy keeping active through CrossFit, playing football and hiking. I’m a keen Liverpool supporter and enjoy watching them, as well as attending festivals and spending time with friends.

    Professional services are provided under the licence and supervision of Mark Jackson‑Stapleton.

  • George
    Accounts

    George

    Senior Client Manager · Retford

    I started work at Jackson Stapletons in July 2023 after completing work experience a few weeks prior.

    Currently I work under Harry at our office in Retford, where I produce a variety of work including but not limited to, Tax Returns, Final Accounts and VAT Returns. I also engage with clients where necessary to ensure the production of both accurate and understandable financial statements.

    I am currently AAT Level 4 qualified, and I am now working towards my ACCA to become a fully chartered accountant.

    Due to JSA being a fast-growing business I get exposed to opportunities that you would not get elsewhere. This means progression is always right around the corner.

    When I am not at work you will usually find me at the gym or eating. I also enjoy playing football and going on hikes in the peak district. Even when I am winding down, I will still have some form of sport on the TV.

  • Sophie
    Admin

    Sophie

    Marketing & Administration Manager

    I started working at JSA on October 5th 2020. Day to day, I manage the admin department across all offices. I also manage every aspect of marketing within the company.

    I have 9 GCSEs and was awarded a D*D in my Level 3 Diploma for Creative Media, along with a D* in Level 3 Business Studies from college. In March 2022, I completed my Level 3 Business Administration qualification and in March 2024 I achieved my Level 4 Marketing Executive qualification. I worked at Primark from September 2019 to September 2021, balancing that job with the first year of my apprenticeship here.

    What I love about working here is the variety in my role and the chance to get involved in different areas of the business. The people I work with and the clients I’ve met make the job even more enjoyable.

    Outside of work, I love spending time with my family and friends. I enjoy going to pilates and travelling to new places, whether it’s within the UK or abroad.

  • Dave
    IT

    Dave

    IT & Development Senior

    I manage the servers, network, phone system, PCs, and general IT equipment here at JSA. I also develop web apps and create software robots to automate various processes.

    I have over 30 years of programming experience and even more in IT. Before my career in tech, I spent 11 years in the Royal Navy, where I gained experience in a wide range of roles—from being part of a demolition team and boarding party to tracking Russian submarines. I’ve programmed for major financial institutions like JP Morgan, Aviva, and Lloyds Bank, among others.

    What I enjoy about working here is that every day brings something new, keeping me busy and engaged. The flexibility required for my work is something I appreciate, as it allows me to tackle problems when systems are least disruptive. The people I work with are fantastic too.

    Outside of work, I love relaxing with my wife and dogs, traveling around Britain in our caravan. We don’t travel abroad anymore since we won’t leave the dogs in kennels, but maybe one day with a dog sitter. I also enjoy spending time with my seven grandchildren and extended family.

  • Isaac
    Accounts

    Isaac

    Semi Senior Accountant · Retford

    I started my apprenticeship in September 2024.

    I currently spend my time working on accounts and tax submissions, alongside general duties around the Retford office.

    In July 2023 I graduated from Leeds Beckett University and have now started working towards my AAT Level 2 qualification.

    It has been easy to settle in at JSA as there is a great working atmosphere.

    When I am not working, I enjoy going to watch football matches with my friends and going to the gym. In the summer I play cricket and enjoy going for walks around the UK. I also try to travel as often as I can, as one of my passions is visiting new places and exploring different cultures.

  • Husayn
    Accounts

    Husayn

    Junior Accountant · Retford

    I joined Jackson Stapleton in March 2026 after having done work experience in the previous October and will begin my apprenticeship in June 2026.

    On a day to day basis I am involved in various tasks for our clients, from payroll and bookkeeping to accounts preparation, tax returns and everything in between.

    I have settled in easily here at the Retford office under the mentorship of Isaac, George, and Harry, who I find very approachable and are invested in helping me succeed here. In particular, it is reassuring knowing that their paths into the company came about in a very similar fashion to mine.

    Outside of work, I like to take care of my health through the gym and other recreational activities. I am also heavily involved in helping out at the charity and boarding school my dad works for, this allows me the opportunity to travel all around the country and meet many new people.
