‘We enjoy working with this clever and knowledgeable team. Their huge experience shines out, and they have great strength and depth. They are able to turn around complex matters with great speed and skill. They always know the right questions to ask to get the best out of us and produce the best result for us.’

‘Dario Dagostino and Mark Devane are exceptional. Dario should be praised for his huge knowledge of all things “regulator”. He has such vast industry experience that he is great at reading the nuances and knowing how we should react to and interpret things. Mark Devane has superb attention to detail. His probing questions mean that we produce our best work and give the best account of ourselves.’

‘Joe Kelly and Katie O’Connor are extremely responsive and proactive in their advice and in responding to us and advising us. They understand our concerns and our business needs and adapt their advice accordingly.’

‘Katie O’Connor and Joe Kelly are practical, efficient and responsive and give advice that has business and real world application as opposed to being a high-level repetition of legislation.’

‘ALG anticipated our needs and prepared us for all of the procedural steps of our legal process before they occurred. That aspect alone was invaluable. ALG is very strong with technology and offers IT solutions to make otherwise overwhelming tasks effortless. ALG has expertise in various domains of law, which helped with finding experts for our specific legal issue. The lawyers impressed me with their interpersonal skills in our relationship. They did it without unnecessary and tacky strategies such as having “client relationship managers”. The deep expertise of the lawyers is immediately obvious. Their billing is very transparent. Our partner made sure to forecast the costs of their services, of experts and of outside counsel as early as possible.’

‘The quality of Katie O’Connor’s work is exceptional, and this was combined with remarkable availability on her part. Although I know that this is not factually true, it felt like my company was her only client. Her meetings were short and on point, and her written advice immediately clear. ALG is strong on anticipating the client’s needs.’

‘Joe Kelly is wise, considered, independent and tough – both with clients (giving appropriate realism) and the authorities (defending clients’ interests). He is well supported by Mairead O’Brien.’

‘Unlike other law firms which sometimes just provide legal analysis, MHC’s advice is very solution focused.’

‘The individuals are client focused. Communication is prompt. The legal ramifications for my team are carefully considered. Solutions can be non-traditional but effective – individuals within the firm can think inventively. Shane Reynolds is a standout partner.’

They have consistently impressed me with the depth of their knowledge, experience and judgement.’

‘The team has a very strong set of partners and associates.’

‘They were very approachable, and very considered in identifying how they could help and who would help. Their communication with me was excellent and they were respectful and professional.’

‘I was more than pleased that they had an excellent understanding of the law and systems relevant to our query. In addition, they had a clear understanding of our need to understand why these systems sometimes failed, showing a wide grasp of the context in which the law operates. That understanding of the law, and the context in which the law operates, was precisely what we wanted and makes the firm stand out.’

‘Unlike many other legal firms, the interaction with partners and associates at MHC is quite personable, in a professional, friendly, non-intimidating way. The team possesses an abundance of expertise and experience and there is strength in depth across the various elements of the practice, which generates confidence in their clients. There is a steady stream of young, smart solicitors being recruited and, once ready, quickly given responsibility. Communication and engagement during the pandemic was excellent and the use of technology supported the continuation of professional support throughout.’

They are friendly and empathetic, with an abundance of emotional intelligence.
