"I've been using Simplex for almost a year now, and I'm very happy with the service they've provided. A month ago, I had my audit, and I couldn't have asked for better help than what Ms. Catherine Games provided. She helped me understand the entire process and assisted me in gathering all the information requested by the officer. From day one, she was very kind until the completion of my audit, which was a success."
"Simplex has been taking care of my company for quite some time now and they're a dream to work with. They do everything for you so you're not worried about if your company is missing something and they're very thorough. In the audit process, Hansey Reyes is the best! She makes sure all documents are uploaded on time and she's very knowledgeable about it so she can offer good advice in the event you have problems in any of the areas DOT looks at."
"Simplex have been very beneficial to our company and we appreciate everything they have done to maintain us in compliance all the time! Special thanks to SAM Christianne Espinoza and Lilian Medina, as they have been the key to our success!"
