[2:48] On with the Show! Our guest today is one of the modern trailblazers of risk and insurance. She is Sierra Signorelli, the CEO of U.S. and Commercial Insurance at Zurich. She is also one of this year's Spencer Educational Foundation's Funding Their Future honorees.

[3:16] Sierra is here today to discuss her career development, her career journey, how it evolved into a global leadership role, and some words of wisdom for the next generation of risk and insurance talent. She has a lot of great insight and takeaways for us all. Let's get to it!

[3:37] Interview! Sierra Signorelli, Welcome to RIMScast!

[3:47] Justin and Sierra discuss longtime mutual friend Marya Propis. Sierra says their paths crossed early in their careers at AIG. They got to know each other through the Women's Executive Leadership Initiative Program.

[4:09] Sierra says quite a few exceptional women in important roles in our industry came out of that program cohort. It's fantastic to come back together with Marya for this event.

[4:37] Sierra studied environmental science. She tries to live and work with a sense of purpose. In university, she wanted to make the world a better place with environmental science.

[4:58] Sierra says there are areas of overlap between insurance and environmental science. Her initial work out of school was about understanding changing weather patterns, flooding, epidemiology, chemistry, liability, and toxic tort. She leans on what she studied.

[5:33] Sierra says that in school, they studied Earth Systems Science. Much of the modeling they did in school is the same modeling that Cat modelers do at Zurich.

[6:04] Sierra first worked at an environmental engineering consulting firm. A colleague left to join a new company. He called her to come and interview. It hadn't been on her mind, but on his recommendation, she interviewed. Meeting the people, Sierra was intrigued.

[7:08] Sierra says once she joined, she never looked back. She joined as an underwriter doing environmental insurance, so it tied to her background. It felt like it was her own little business. It was her responsibility to build a portfolio of business and build relationships with brokers.

[7:37] Sierra says it was fascinating. The industry gives lots of training, both industry-led and within companies. The opportunity to learn was fun. Sierra felt it was a great place to start to build a career.

[8:20] Sierra has had a few meaningful career pivots. As an underwriter, transitioning to her first manager role was a big step. It taught her that you have to have sponsorship or support within an organization to get the next roles.

[8:47] Sierra says it was a big step from being an individual contributor to leading a much larger team. Having somebody willing to put that on her was really important. She will be forever grateful for that first step.

[9:12] Sierra says the next meaningful step was from running a business in a region to being a CUO for one of the businesses globally. The organization restructured and put Sierra across lines of business she had no expertise in. That was a huge shift for her.

[9:40] Sierra was no longer the deep expert, but she had to lead a team of experts and be credible with those individuals. Most of them had 30 or 40 years of experience. Sierra was in her early 40s. It was a fantastic opportunity that somebody was brave enough to give her.

[10:09] Shortly after, Sierra moved from New York to Asia. It was quite a difference. She took that step because she was in a global role. She says, even though she traveled a lot and she's curious about people and cultures, it's not until you sit somewhere that you really experience it.

[10:39] Moving overseas and being on the receiving end of New York gave Sierra an appreciation for sitting in the market. At that company, all brilliant things came from New York, and the rest of them had to figure out how they added value. The time difference was a challenge.

[11:24] Sierra says the time difference has a huge impact on your life. The company wanted to become more global and had placed executives all over the world in different hubs. When you have 3,000 people in one area, everything is time-zone-centric to them.

[12:01] As a global leader, in another time zone, you have to be comfortable not participating in everything and having people who represent you on your behalf, knowing when you really need to engage. You need to know to move the time if you won't be coherent at 3:00 a.m.

[12:24] Sierra went back and forth once a month from Asia to New York to do Business Unit Reviews. It takes a lot out of you. The world has changed, and she does many more video meetings. Global travel has an impact on quality of life.

[13:00] During those years, Sierra was raising children. They started pre-school and kindergarten in Asia. Sierra says she couldn't possibly do it unless her husband was on board; he had a career that was more flexible, and he was willing to step up. That's a family discussion to have.
