"PKF OCLH’s advisory team were a critical part to our acquisition of Lily O’Brien’s. PKF’s innovation, efficiency and hands on approach was an instrumental factor in closing out our acquisition. This in turn ensured that the Board of Colian Holding S.A. achieved our end goal, no matter what problems were encountered. We look forward to working closely with PKF OCLH in the future. "

Piotr Lagowski – Member of the Supervisory Board, Colian Holding S.A.

"PKF were a key part of our sales process when Agile Networks was acquired by Plannet21 Communications. This was a very sensitive deal given the directly competitive nature of the two firms and we found PKF gave very sound strategic advice which allowed us to achieve the deal our shareholders were looking for. Unlike some of the bigger firms you had direct access to subject matter experts without going through layers of bureaucracy and at all times we really felt we had a partner at our side helping us through a complex and challenging process. Put simply PKF became an extension of the Agile Networks team and were a key component a successful outcome."

Darragh Richardson – Managing Director, Agile Networks

“We have been very satisfied clients of PKF O’Connor, Leddy & Holmes for more than 30 years. Originally they were our auditors but became advisors, tax consultants and a sounding board for advice about expanding our business. We have always found them to be efficient, reliable, thorough and above all flexible. Having the same staff for years meant that our point of contact remained constant and they came to understand our problems – sometimes better than we did!”
