Mark is an entrepreneur and insurtech innovator with over 45 years of experience within the insurance industry. Mark’s first 20 years were dedicated to the Lloyd’s broking community, which was followed by his entrepreneurial dedication to found both Wildnet Group and Castel Underwriting Agencies.

James Montgomery (“Monty”) has been with Ryan Specialty since 2016 when he joined the firm’s transactional risk managing general underwriter, Ryan Transactional Risk (“RTR”). Monty is currently a Managing Director of Ryan Transactional Risk and has been instrumental in the growth and global consolidation of the RTR platform.

Mark and Monty are colleagues and executives each with exceptional track records of building, innovating and executing on growth initiatives at the highest level. We are confident they will integrate and continue to scale the exceptional talent and resources of RSUM International, Castel and Innovisk and accelerate our international expansion.”

Discussing this new appointment and transition, Mark Birrell said, “I’m excited to take on the new role of Executive Chairman and focus on the continued international expansion in both product and region. The growth of Ryan Specialty’s international expansion, especially with Innovisk now on board, requires a split role of our international executive leadership. Monty is a proven talent and leader, and I’m very much looking forward to working closely with him to expand our offering for our clients and trading partners.”

James Montgomery added, “I am really looking forward to this next chapter in my career as CEO of RSUM International.

We are in a time of enormous opportunity, and I look forward to continuing to deliver exceptional service, outstanding outcomes and innovative solutions for our clients and carrier trading partners internationally. I could not have achieved this appointment without the continued support of the amazing people with whom I work at Ryan Specialty and in the wider industry.”
