“Sharon has contributed over 16 years to Tokio Marine HCC, and her achievements will not be forgotten. Her work ethic, command for complexity and dedication to the company have been exemplary. She has been a mentor to many, and her influence has made an impact on all of those with whom she has worked. I extend my warmest congratulations and wish her all the best in her retirement,” said Susan Rivera, Tokio
Marine HCC’s Chief Executive Officer.

“While Sharon will be missed by all of us at Tokio Marine HCC, her retirement is well deserved. Her hard work and diligence have greatly benefited the company. I wish her the best in what lies ahead,” added Mike Schell, Tokio Marine HCC’s President. 

“I am delighted to have Tom take on the role of Chief Financial Officer,” continued Ms. Rivera. “He has the right background to lead our finance organization with deep experience in risk, actuarial and capital functions that will benefit us as we grow and innovate as a specialty insurance company.”

In continuing the natural progression of transition within the finance organization, Mark Buechler, Senior Vice President and Chief Accounting Officer, will also retire effective April 1, 2021. Mr. Buechler has served Tokio Marine HCC for over 32 years in various finance positions of increasing responsibility. Jeff Turner, Vice President of Corporate Reporting, will be promoted to Senior Vice President and Chief Accounting Officer upon Mr. Buechler’s retirement. Mr. Turner will report to Mr. Weist, and Mr. Buechler will continue to serve Tokio Marine HCC as a part-time consultant to ensure a smooth transition.

“Mark’s dedication and contribution over his 32-year career with Tokio Marine HCC has been nothing less than outstanding. I’m sure that retirement will offer Mark many new endeavors, which I know he will embrace wholeheartedly, just as he has done here at Tokio Marine HCC. I wish him the absolute best,” commented Ms. Brock.

“It has been my pleasure to work with Mark over the years. I am confident that he will find the same success in retirement that he has experienced during his time with Tokio Marine HCC,” added Mr. Weist.
