Aspen Insurance Names John Welch as Group CUO
Aspen Insurance Holdings Limited has announced the promotion of John Welch to group chief underwriting officer (CUO), effective August 1. Welch joined the company in June 2023 as CUO for its reinsurance division, bringing with him more than 30 years of executive-level experience.

In his new position, Welch will report directly to Christian Dunleavy, group president and CEO of Aspen Bermuda Limited. He will oversee underwriting across all business segments, driving Aspen’s overall risk strategy.
Additionally, Aspen has been actively investing in internal leadership. Just months ago, the company promoted Jon Kattman to head of inland marine, signaling a continued focus on segment-specific growth.
Mosaic Insurance Adds Industry Veterans to Its Advisory Board
Mosaic Insurance has strengthened its advisory board with the addition of three new members: Peter Breitstone, George Hanna, and Tom Kim. Each brings specialized experience in areas such as cybersecurity, private equity, and insurance innovation.
The board, originally chaired by veteran insurance executive Joe Boren, aims to provide guidance across Mosaic’s growing global operations.
Peter Breitstone
Breitstone currently leads a consultancy and brokerage that advises insurers, insurtechs, private equity firms, and healthcare organizations. He is known for launching one of the industry’s earliest boutique environmental brokerages. His prior affiliations include Goji, Zurich North America, and Aon. Breitstone holds a law degree from Temple University and is licensed to practice in both New York and Washington, D.C.
George Hanna
Hanna has served in legal and regulatory executive roles across the insurance and tech sectors. Notably, he provided legal counsel during the sale of Secureworks to Sophos. His previous leadership roles span organizations such as YP Holdings, Wellmark Blue Cross Blue Shield, and BellSouth Corporation. Hanna earned his undergraduate and law degrees from the University of Miami in Florida.
Tom Kim
Kim recently retired from his post as managing director and global risk manager at KKR, where he spent two decades building insurance solutions for over 1,000 private equity deals. He has also held roles at Cerberus Capital Management and Aon. Kim holds degrees from the University of Massachusetts Amherst, Loyola Marymount University, and Loyola Law School in Los Angeles.
This board expansion follows the promotion of Yosha DeLong to global engagement officer at Mosaic, a move announced last month as part of the firm’s push toward broader stakeholder alignment.
