Phillip Simpson

Founder & Managing Director

I have been in the accountancy business for coming on 18 years now and pride myself with the success and growth of 525 but this would not be possible without the dedication of my staff and the relationships we have built up with our clients. At 525, you not only receive a first class service and but also the personal touch, from myself down to our juniors as we treat all our clients like family.
