Starting Your Career at ORBA


“There have been many reasons I have enjoyed being an intern at ORBA this summer. Being able to work and meet people from all the different departments has been an awesome experience. Everyone has been extremely friendly and even with the difficult circumstances of completing an internship during a pandemic, ORBA has done a great job of helping interns get in-office experience without actually being in the office.” – Tatum King, Summer Intern

“Over the last couple of weeks, I have been able to get a better understanding of the accounting career and develop skill-sets that will help me in the professional world. Adjusting to a solely remote internship was a truly unique experience that ORBA made easy to do. I have met some of the nicest and most knowledgeable people in our field and always felt comfortable seeking out help. My favorite part about my experience was my ability to not only work with the traditional audit and tax departments but also worked with ORBA Wealth Advisors, Cloud CFO services, marketing and other departments. By working with these other groups, I had a chance to see how different fields operate while learning about the things I enjoy.” – Ambereen F. Saiyed, Summer Intern
