Ayoub and Associates is by far the best place I have had my taxes done at. We have been coming here for a few years now and I must say the service is wonderful. All staff members are professional, polite, calm, and helpful. When we get there, we are always greeted kindly and offered beverages while we wait. Every time we have been in they are always on time with our appointment and have all our documents ready to review. It's a very smooth & painless process. We are in and out of there within the hour which is nice since we usually go during our lunch time. Very convenient! I've also

When I met with Sandy, she was extremely welcoming and knowledgeable and gave me some great advice and information. I was so caught up in our conversation that I lost track of time and it wasn't until I left that
