G&W Labs

Carl Greenblatt founded G&W Laboratories, Inc. in 1919 upon his return from military service as a pharmacist with US forces in World War I. While establishing a reputation as an innovative specialist in suppository dosage forms, Carl guided G&W Laboratories with an uncompromising commitment to product integrity and customer service. In 1945, Carl’s son, Burton, also a registered pharmacist, returned from military service in World War II and joined the small but growing company.

During the post-war years, G&W expanded its product line beyond suppositories, into creams, ointments, gels and liquids. G&W moved to a larger state-of-the-art laboratory and production facility, which now exceeds 180,000 square feet in South Plainfield, New Jersey. Continuing the high ethical standards and customer focus established by Carl and his son Burton Greenblatt, G&W is still family owned and operated.
