Marcella A. Maduri
Founder CPA, CGA
After 15+ years in banking, I became a Chartered Professional Accountant (CPA) to help individuals and businesses build a stronger financial future through strategic tax planning and advice. For over 30 years, providing peace of mind and solutions that drive positive momentum has been the foundation of my work.
My experience in banking, pension administration, and group retirement led me to become a Certified General Accountant (CGA) in 1992. Today, as a CPA, my expertise in the Canadian financial market allows me to assess and tailor solutions to each client’s unique needs. I’ve built a diverse client base, working with professionals and individuals across various industries.
Katka Pospisilova
Staff Accountant
With over 15 years of accounting experience and a strong educational background, I help clients with a deep understanding of business accounting matters. I studied accounting at the Commercial Academy and Business College in Brno, Czech Republic, gaining hands-on experience through various accounting roles. In June 2012, I graduated with high honours from Sheridan Institute with a Small Business Bookkeeping Certificate.
I originally joined MAM CPA in 2009 before returning to my home country, the Czech Republic, in 2015. In January 2022, I rejoined the team remotely and am thrilled to contribute from a different time zone. My focus is on corporate year-ends, bookkeeping, and preparing personal income tax returns.
Leslie Buckler
Senior Staff Accountant
Connecting with clients is the most meaningful part of my work in personal taxes, bookkeeping, and preparing year-end financial statements. Since completing my work terms, I’ve taken on additional responsibilities and now manage year-end engagements for our business clients. I also provide bookkeeping support to clients who handle their accounting in-house.
I joined the team in early 2013 as a co-op student from Sheridan College Institute of Technology and Advanced Learning. I now hold an Honours Advanced Diploma in Business Administration – Accounting.
Catherine Reyes
Office Administrator
I am always eager to provide the best service to our clients through detail-oriented oversight of all accounts. After completing the Business Accounting program at Sheridan College in 2022, I worked as an office administrator at another accounting firm before joining the team in September 2023.
My role includes bookkeeping, responding promptly to Canada Revenue Agency (CRA) notices and requests, and office administration. Outside of work, I enjoy long hikes and spending time with my dog.
