About The Nathan Agencies

Our Leadership

The Nathan Agencies began in 1969 when Ron Nathan founded what was initially called The Nathan Agency. The agency initially worked primarily with life insurance and investment products and in 1978 it moved to its current location on Gatehouse Road in Amherst.

The following year Ron Nathan purchased the Amherst Insurance and Real Estate Agencies and the name became The Nathan Agencies. Under this umbrella, Amherst Insurance Agency offers property and casualty products, and the Amherst Financial Services Agency provides life insurance, health, insurance and financial services products through Lincoln Investment. In December, 2012, long time owner/ employees Glenn Allan and Anna Holhut purchased the stock of Amherst Insurance from Ron Nathan. In January of 2017, Christian Sulmasy, as part of a succession plan, acquired Amherst Financial Services. The Nathan Agencies/ Amherst Insurance and Amherst Financial Services are still housed together at 20 Gatehouse Road in Amherst. They are still working together providing complete financial and insurance services.

Since then, The Nathan Agencies has steadily grown to become a well-known full-service insurance and financial planning firm in Western Massachusetts. The success of the agencies has been supported by our emphasis on top- quality customer service. The Nathan Agencies’ highly trained staff is dedicated to providing the superior level of service our clients have grown to appreciate over the years.

We live in an increasingly complex world, and the insurance and financial services industries are certainly no exception. Each department within the Nathan Agencies is overseen by a staff specialist who is cross-trained in many areas to help our clients better identify areas in which they may be insufficiently protected.

To keep abreast of the latest developments in this dynamic industry, our staff members are continually improving their insurance knowledge by attending continuing education seminars, courses, and degree programs. Also, The Nathan Agencies’ high tech business environment enables us to help our clients to better communicate with us and expedite information gathering and coverage changes.

When you work with a member of the Nathan Agencies’ staff, you can always count on being treated with respect, competence and accountability.
