Singer Lewak Greenbaum & Goldstein LLP

Singer Lewak Greenbaum & Goldstein LLP (SLGG) is the largest certified public accounting firm headquartered in Los Angeles, California. Since our beginning in 1959, we have served a broad range of clients. As the firm has grown over the years, we have not lost our commitment to personal service or our focus on clients' needs.

Phil Singer originally founded the accounting firm which would become SLGG. He was working for another CPA firm before starting his own practice in 1959 where Bernard Lewak’s father was one of his clients. Bernard Lewak, a UCLA student, joined Phil as a part-time employee. Together they worked out of a one-room office in an old stucco building above a grocery store belonging to a client; their furnishings consisted of only one drafting table.

After graduation, Lewak joined Singer Gottfried and Associates. About two years later, Singer reunited with Lewak and joined with another partner to form Singer, Ross & Lewak. In 1962, Ross withdrew and the firm became Singer, Lewak & Associates.

Norman L. Greenbaum joined the partnership and his name was added to the firm. As growth continued, Harvey Goldstein, a graduate of California State University at Los Angeles, joined the firm. By mid-1967, Harvey merged his practice with the others and the firm became Singer Lewak Greenbaum & Goldstein.

By 1972, Harvey Goldstein became the Managing Partner and as the firm grew, SLGG moved to its Wilshire Boulevard office. When the firm expanded its services to Orange County in 1979, this new office was managed by partner, David W. Krajanowski. As business continued to grow, SLGG opened a third location in Ontario, CA in 1999, headed by partner David Kamath, to serve the inland empire business market.

In 2003, Harvey Goldstein became Chairman and was succeeded by David W. Krajanowski as Managing Partner of the firm. Today, the firm is comprised of more than 200 professionals, including 28 partners and supporting staff.

Today we provide professional accounting and business management services to clients ranging from individuals to family-owned businesses, nonprofit businesses, law firms and public companies of all sizes.
