Profile bio

About Natasha Castelli

I navigate cross functional groups and competing goals with a solution-oriented focus that empowers teams with a collaborative approach. My practical and hands-on methodology impacts change in organizations that translates into results. As a consultant, I worked with over 10 private companies, 6 public companies, and 3 companies during their IPO transition, including 9 ASC 606 adoptions for public and private companies. I never take myself too seriously, have a deep love for food (especially sweet treats, please pass the cookies), and love working with people – which makes me not only an effective resource but an ally and friend to my colleagues.

Listed skills include Sarbanes Oxley Act, Internal Controls, Gaap, Revenue Recognition, and 17 others.
