Update 6/17/20

Essentially, we will not be coming into contact with clients.

Our stores are open for business. We are allowing customers inside, but we ask that you please wear a mask - and follow social distancing guidelines. We would love to help.

If you have any questions, please ask. We urge you to visit NY Governor Cuomo’s Issues Guidance on Essential Business List.
