They liaised beautifully with the business to obtain the necessary information in record time and as a result we achieved all of our clearances in good time. The team’s knowledge and experience meant that you could relax in the knowledge that you would be guided effortlessly through the whole process.

    Very responsive and professional.’

    Anna Delahey was extremely efficient and personable. I received very prompt and regular updates on the progress of the filings and clearances which enabled me to provide a similarly effective service to my senior management team. Marta Garcia is obviously a very experienced partner and made you feel in very safe hands.’

    The team is very pragmatic. They are very capable to close an acquisition within a specific timeframe. They are very hard working. They are solution driven and find practical solutions to difficult problems without costing the company an arm and a leg. This was the first law firm where I felt the company was not being squeezed for every cent it had. They looked at the deal structure and applied their fees to the acquisition size.’

    They take the time to understand the issues. Probe with questions to get the full story.’

    We felt there were two key strengths the team exhibited. First, they were very pragmatic and second they were very responsive. This combination worked very well for us given that we were engaged in a small, but time critical, business deal. They seemed willing to work with us using our systems and preferred manners of communication and this made it very easy to work with them. In general, I would say that my experience working with the team was an absolute pleasure and I would actively recommend them to others. There was a really good fit in terms of like-mindedness and culture in our interactions.’

    We felt well-guided by the depth of knowledge the team presented, the pragmatism displayed and the pace by which the transaction was going along. We were impressed by the co-ordination of the various disciplines required within the team.

    Marta Garcia is a very good technician on all things competition law related.
