Valley Dental Supply was established in 1927 in Los Angeles by M.A. "Mike" Herman as a sole proprietorship. He was joined in 1933 by R.L. "Bob" Slater who became a partner in the business in 1945. In 1948 the business was moved to North Hollywood, and began increasing in size with the addition of new sales people.

With the passing of the Mike Herman in 1972, Bob Slater became full owner, and then once again moved Valley Dental in the mid 1970's to it's present location in Burbank. Then in 1987 four of the salesmen, the current owners, purchased Valley Dental Supply Inc.

In 1995, Valley Dental continued its growth by adding branches in both Phoenix, and Prescott, Arizona to service the needs of the ever growing southwest.

In 1997 Valley Dental Supply opened a branch in Orange County,
California. In 1999 the Albuquerque, New Mexico branch was opened, continuing its growth in the western States.

VDSI has kept it's philosophy of honest and personal service to it's clientele, along with a commitment to progress and competitive pricing.
