A Brief History

Our roots go back to the business law firm started by our founder, Peter Mogan, in 1990. Propelled by a growing transaction division and a clear vision to develop British Columbia’s first boutique law firm with a focus on Mergers & Acquisitions, Peter brought Nathan Daniels and Ben Slager on board in 2011 and together they formed MDS in 2012.

Over the next few years, highly sought-after lawyers and paralegals would become part of the MDS team, cementing a commitment to excellence while enjoying the camaraderie, agility and focus of a boutique firm.

Today, MDS is an industry leader in mid-market transaction services and is continually evolving its unique processes and client experiences to deliver exceptional outcomes.

We combine strong people skills, deep experience in our craft, a love for business, high efficiency and a collaborative mindset to allow us to do good work, even if no one is watching. That’s our way of doing the right thing.

Celebrate Successes

When we put all of this together, we are able to achieve great results and at the same time have grateful clients who know that they have been supported and empowered every step of the way. Together, we celebrate our successes.

I’ve always been impressed with the way Mogan Daniels Slager supports their clients. They have a sharp mind for business that allows them to be agile and straightforward, but they also don’t forget about the human side of business. They are approachable and personal when it matters. That’s incredibly important to me and the way I do business, which is why I’ve trusted MDS for more than 10 years.

The MDS team helped us complete a very complex, nine figure investment in the real estate and senior’s care industry. The transaction involved three companies, two lenders and a structure that changed mid-way through the process. All along, MDS guided us through and were adaptable in approach. MDS provided exceptional value for money and combined to be strategic, detailed and efficient in leading the parties towards a successful close. We will not hesitate to use them again.

We’ve partnered with MDS on a number of transactions. We find their guidance on both technical and higher-level issues very useful. Highly recommended for those looking for reliable guidance in M&A transactions.

David Phillips
Partner, Yellow Point Equity Partners

When looking for a law firm, I wanted to find a business partner who would help me grow my business. A firm who understood that clients are people and that building and maintaining strong relationships are the basis for successful business growth. I found that in Peter Mogan, and Mogan Daniels Slager LLP. Fast forward 23 years; after multiple acquisitions, some dispositions, countless term sheets and contracts, a variety of business and holdings structures in the US and Canada, and Peter Mogan along with Nathan Daniels and other senior lawyers in the firm still provide valued advice and technical expertise, which allow me to lead, be strategic, and focus on growing my business.

I have had the pleasure of going through multi M&A transactions with MDS Lawyers, the last one with Rosanna Tallarico as the lead. She is very knowledgeable and competent on all aspects of the process. She diligently and methodically goes through all the steps. Rosanna, it was a pleasure working with you on the last project and looking forward to the next one!
