To our customers,

As the Covid-19 crisis grows, we would like to take a moment to address the situation as best we can. Remember, this situation is very fluid and changing rapidly as many states, cities, CDC and the country have been making mandates rapidly and ever changing.

With that said, We are staying open to the public. Precautions that we are taking on include disinfecting and wiping down all surfaces, door k***s, doors and walls. Everything and anything that we can keep sanitized to ensure our customers that they are in good hands. We are also insuring all of our team members to constantly wash their hands and to stay home if they feel ill. We ask that you do the same.

We advise everyone to keep washing their hands, keeping distance in public to ensure not only the safety for yourself but for others and your loved ones.
