Our People

Maria Fellows joined Leone, McDonnell & Roberts as a full-time staff accountant after interning with the firm as an undergrad. She earned her Bachelor of Science in Accounting from Southern New Hampshire University (SNHU) in 2023 and her master’s degree in professional accountancy at SNHU in 2024.

Maria brings a unique blend of experience to her role, having worked in customer-facing positions before launching her accounting career. Her early work experience taught her the importance of communication and problem-solving—skills she applies daily in her work with clients at LMRPA.

Maria’s favorite aspect of accounting is the sense of accomplishment that comes with completing complex tasks. She compares her work to solving a puzzling — challenging, but everything fits together in the end. Her favorite thing about Leone, McDonnell & Roberts is the firm’s welcoming and supportive environment where her colleagues have made her transition from intern to full-time staff both seamless and enjoyable.

As a child, Maria dreamed of owning an ice cream truck or becoming a teacher. Now, when she’s not in the office, she enjoys watching basketball, playing golf, and snowboarding, her favorite pastime.
