    I have worked with a number of accountants over the years and have never found another who offers the same level of care, support and professionalism. Our sound working relationship over the last year has ensured that both our businesses prosper. The Birchtree Sullivan team have looked after us admirably and guided us successfully through pitfalls that any business would expect to encounter. I am delighted with the professional and efficient way in which you do things. In particular, you do what you say you are going to do, do it when you say you will and all the while keeping me fully informed and explaining everything in ‘plain English’. Perhaps those things are not a lot to ask, but these days are quite rare. They have made a big difference to my business.

    Birchtree Sullivan makes my business life so much easier. They’ve helped me with cash flow, forward planning and taxation, reducing my personal tax liability. I would have no hesitation in recommending Russell and his team and would be happy to have a conversation with anybody who would like to know more.

    Birchtree Sullivan has helped us every step of the way in setting up our charity. They had explained in detail but in simple English the best legal form for the charity based on our circumstances. They are great at producing final accounts but what we value most is their proactive approach to our organisation and taking care of all aspects of accounting services.

     I get on really well with the partners at Birchtree Sullivan. They were local and had a similar, fresher way of looking at things. We speak on a regular basis. They are still very interested and are an incredibly good sounding board, which I find invaluable. We’ve always had a close relationship; I think that’s why it all works so well.
