Jonathan originally joined the firm of Butcher Burns as an articled clerk and, after qualification, he was admitted as a junior partner and later became the senior and managing partner. Subsequently he was the CEO of that firm until it joined with Teacher Stern on 1st May 2013 when he became a consultant to Teacher Stern LLP.
Over the years, he helped guide the growth of Butcher Burns and by the time it merged with Teacher Stern LLP it was several times its original size. His early experience was as a general commercial litigator but later he moved into the field of property work where he gained substantial experience of residential and commercial property developments and investments and property law. Later he specialised in company commercial law, retaining an active interest in property work. As a consequence of the three different areas of previous specialisation, Jonathan gained extensive experience and is now a consultant at Teacher Stern.
