Larry Greenhaus' accounting firm has been a fixture in New Milford since 1960.

These days, the CPA business' name is Greenhaus, Riordan & Co. LLP and the day-to-day administrative duties are handled by Timothy Riordan, a partner since 1981.

Mr. Greenhaus, 83, still keeps an active hand in the firm. His presence affirms the 52 years of personal, hands-on service the business has come to stand for, Mr. Riordan said.

"I grew up in New Milford, went to elementary school on Main Street and graduated from the high school on East Street in 1946," Mr. Greenhaus recalled.

"In my senior year, I was deciding whether to go into engineering or accounting," he said. "In those days, you could walk right into the superintendent's office and have a conversation with him. I went into Weldon Knox' office and told him what I was struggling with."

Mr. Knox' advice set in motion Mr. Greenhaus' CPA career.

It began in 1950 in New York City. By 1960, he and his wife, Gloria, had moved back to New Milford, locating an office on the east side of Main Street.

In 1963, he closed his New York City office. By 1968, his firm was comfortably housed in its present location at 3 Aspetuck Avenue.

"Larry was always admired by the people in the community," said Hank Anderson, retired partner of Cramer & Anderson law firm. "Professionally, I found him to be excellent. The public respected him for his honesty and integrity."

Greenhaus, Riordan & Co LLP has four offices -- staffed offices in New Milford and Danbury and satellite offices in Orange and Lakeville.

Office staff is kept small, with eight in New Milford and three in Danbury. Yet clients range from residents of Connecticut, New York, New Jersey, Massachusetts, Florida and California.

The firm specializes in advising on intricate questions regarding mergers, acquisitions and transactions for businesses.

It also offers estate, business and individual tax services as well as financial budgeting and financial forecasting.

While most staff members have been with the company for 20 years or more, their newcomer of four years, Mario Lucibello, writes a blog for the firm's website.

Today, much communication with clients is done electronically through a secure portal.

"The major change in the last 10 years has been our IT services," said Mr. Riordan. "When I came to work for Larry in 1978, I knew he was forward thinking."

Mr. and Mrs. Greenhaus now live in Danbury and spend five months of the year in Florida. He stepped down from the New Milford Hospital board of directors in 2009 after a 44-year tenure, during which he served as treasurer.

"I was disappointed to see (the hospital is) closing the Family Birthing Center, Mr. Greenhaus said. "When we opened that center many years ago, it was a good thing for the town."

"As a small hometown hospital," he added, "New Milford Hospital has done a great job. I hope that a lot of other things don't get taken away."

"When I was a boy in the 1930s, the hospital was a one-family house," Mr. Greenhaus recalled.

Greenhaus, Riordan & Co. LLP has an office at 3 Aspetuck Ave., New Milford, to which calls may be directed at 860-355-1124, and at 68 Walnut St., in Danbury, 203-748-8000. Visit for information.
