Extraordinarily professional - the moving guys were quite and totally fast - although they overpack (wrapping napkins in reams of paper, for ex). They then stored my belongings in a dry, safe, excellent place for 5 years. Only an antique table was damaged - probably overloaded with stuff.
They helped me to load my truck - at no extra charge when I took things out of storage and even disposed of items for me.
They are very costly, but I would use them just for the peace, security & professionalism
