Contact Mark


Mark is our Senior Partner and Head of the Commercial Department.  He is also responsible for the firm’s Growth and Practice Development.  He is a Solicitor, a Notary Public and an Associate Trade Mark Attorney.  Mark is also a qualified Corporate Finance professional and enabled the firm to become an Affiliate Member of the British Franchise Association.  He holds a Bachelor’s Degree in Law and a Master’s Degree in Commercial Law.

Mark has a broad ranging corporate and commercial practice covering sales and purchases of shares and businesses, commercial agreements of all types, intellectual property matters (including trade marks) and franchising.  He seeks always to provide the best possible advice to clients and solve any legal problems they may encounter so that they can achieve their commercial objectives.

“Mark Lello was always readily available and we were impressed that even when on leave he was monitoring his emails and responded to them if necessary. As the partner, he was the lead in the collaborative working within his team which so impressed us. We feel that he always gave us good advice whilst being responsive to our queries and wishes.” (Legal 500 2021).

“We found that the whole team worked well together, and communication between all involved was exceptional. We always knew that whoever we spoke to was up to speed on all aspects of the process. They were also very good at liaising with other professionals and responded quickly to our emails.” (Legal 500 2021).

“What stands out is the clarity of advice and responsiveness of the practice.” (Legal 500 2021).

“From the start they were very clear about what they could do and how they would work on our behalf.”  (Legal 500 2020).

“Mark was readily available at all times to answer questions.  This is unusual as at many firms you often have to deal with someone more junior.”  (Legal 500 2020).

“The firm was well organised and quick to respond to any contact and were able to provide swift answers to any query.” (Legal 500 2020).

Mark has been described by the Legal 500 in 2020 as ‘the stand-out lawyer at Parker Bullen’ in his role as the practice head for Corporate and Commercial work, heading up a practice which handles such work across the technology, healthcare and professional services sectors, as well as having experience handling charity sector work.  The Commercial Department carries out corporate transactions, fundraisings, restructurings and joint ventures, as well as advising on intellectual property matters.  In Mark’s view all the lawyers at Parker Bullen are ‘stand-out’ lawyers.

Mark is delighted to be our partner responsible for trainee recruitment and supervision. During this ambitious phase of Parker Bullen’s growth, our trainees form a vital part in our firm and its future.
