Our Story
Our story from
25 years of experience
Aldo Cotrina founded Wall Street Business Advisors, inc. 25 years ago right here on Long Island, because Aldo believed that business owners and families in Suffolk and Queens County deserved something the big national firms weren’t delivering: genuine personal service from an accountant who knew their community, understood their challenges, and was available year-round — not just in April.
We’ve grown since then, but our philosophy hasn’t. Every client works directly with a trusted and experienced accounting professional, not a rotating team of seasonal preparers, not an offshore processing center. When you call, we answer. When something changes in the tax law, we reach out to you. When you have a question in August, you don’t wait until February.
Today, Aldo Cotrina’s team serves hundreds of individuals, families, and businesses across Long Island, from solo consultants in Huntington to multi-location construction companies in Suffolk County. Our team is credentialed, experienced, and deeply invested in our clients’ financial success.
