History
Pioneering Affordable Excellence
Adelsberg & Co. was established in 1957 by Samuel Adelsberg to provide top-notch financial advice to emerging businesses at an affordable cost. Adelsberg envisioned a firm centered around personalized service, offering unique value-added expertise that larger firms cannot match.
Adelsberg recognized that quality financial advice is a major factor in a business’ success, yet it can be costly for many startups. He aimed to provide affordable financial services, sharing in their success and changing the lives of their owners and families. Adelsberg also identified that the bureaucratic infrastructure of larger accounting firms worked against their clients' interests, ignoring the value hidden in analyzing small details and discouraging its staff from such reviews. He aimed to create a forward-thinking and nimble firm to address these issues.
