In 2016, we switched our business insurance to Post Insurance Services and I can't emphasize ENOUGH how amazing Stacey and her team are! Five years later and Stacey still treats us like we're a new Client. She is so quick to respond to our requests and/or questions, extremely knowledgeable and always helpful! Honestly, I can't say enough positive things about Post Ins., Stacey, and everyone working in the office! Thank you for taking such great care of TB&Co.

I've been working with Stef at Post Insurance now for a few years. When I initially contacted her she graciously answered all my questions and guided me through the process of healthcare implementation for my business. She's always been responsive and a good source of information on the ever changing healthcare market. While I am at the opposite end of the state from their offices I feel like I have a local partner in the Insurance industry with Post Insurance.

Absolutely the best experience I've ever had with any insurance broker. If Stef and the rest do not know the answer, they know where to get it. Post Insurance never makes one feel as if one is alone and lost in the ever-changing landscape of business and health insurances.

Leaving our previous insurance broker five (5) years ago was not a decision I made lightly however, in retrospect it was one of the better decisions I made for my business. The customer service that we have received from Stef Kazarian and others at Post Insurance has been phenomenal! We have never felt that we were "just another client.” The diligence put forth by Stef during each renewal period has been evident year after year. Her research has always been very thorough and she’s been able to present us with multiple options including the optimum blend of coverage for our dollars. Our employees have always received excellent claim service and any problems have been resolved efficiently. Because of Post Insurance, we have been able to limit the rising costs of health insurance while continuing to offer our employees an affordable and comprehensive plan.
