Thought Leadership


Q. What was it that drew you to Armanino?

I was looking for a firm that cared about me as a person, and Armanino is an inspiring firm that lifts up its people. In all the conversations I had with the team, I felt the type of genuine kindness that I wanted in my work environment.

Q. What do you predict the future will look like for clients in the industries you serve?

I work with healthcare and nonprofit clients. These two industries shined during the pandemic and I’m confident that they’ll continue to do so. To take full advantage of this opportunity, these organizations must incorporate the best practices that they learned and continue to play to their strengths. I predict that the processes that worked during the pandemic will only improve, as healthcare and nonprofit institutions thrive into the future.

Q. Without naming names, tell us about your favorite client and why you enjoyed working with them.

My favorite client was a facility that had serious financial problems. Together, we determined what were the right places to spend their money and negotiated with the state on their behalf. This changed the entire fabric of the organization, and we were able to raise their workers’ salaries. Five or six years later, I met with someone at an event and shared this same story with her. She started crying and told me that she was one of those social workers who had been able to keep her job and raise her income because of the work we had done.

Q. What’s your proudest moment?

I often ask my kids how they’re going to change the world. My proudest moments are when other parents approach me to tell me that my children have made a difference in their kids’ lives. Whenever this happens, I make sure to let my sons know that they are already changing someone’s world, and small acts of kindness and support are all it takes to make a difference.

Q. What do you love most about your work?

I’m always blown away by the fact that my work allows me to do amazing things for organizations that give back to the community. My team and I enable nonprofits and healthcare institutions to thrive and, by doing so, people who need and rely on them the most receive the benefit of better and more services. To me, that’s everything.
