  Jennifer has been absolutely outstanding to work with. As someone with a demanding job and two young children under 5, I don’t have time for unnecessary back-and-forth, and Jennifer adapted perfectly to my needs. Whether I needed a quick email while juggling work and family or a phone call to walk through something more complex, she was always incredibly responsive.

Most importantly, she was able to save me thousands of dollars while actually improving my coverage. I had a lot of questions and unique concerns throughout the process, from making sure I had proper coverage for a household employee to ensuring I was adequately protected around my pool and property. Every time I threw a new challenge or “side quest” her way, Jennifer handled it with expertise and confidence.

We did run into a few roadblocks with some of the coverages I wanted, but Jennifer never presented a problem without a solution. She communicated clearly, calmly, and effectively every step of the way, making complicated insurance decisions easy to understand.

I’ve never met Jennifer in person, but I trust her completely based on the knowledge, professionalism, and care she demonstrated throughout this process. I genuinely feel like I’m in good hands. The fact that I ended up with better coverage while saving money is just the cherry on top.

I highly recommend Jennifer to anyone looking for an insurance professional who is knowledgeable, responsive, and truly puts her clients first.

  Very honest and helpful. I knew nothing about insurance and not only do I have the best rates for my auto insurance given my situation, but i also am educated as to what coverage I have and why. Highly recommend!

  Jennifer and the JAB team were amazing.  Jennifer was able to switch all our policies from a carrier we have had for 40+ years seamlessly and a quick turn around time.  Not to mention the savings she was able to obtain for us by switching.  Thank you Jennifer.

  Jennifer has been fantastic. She did a very thorough review of my current insurance and was able to get me improved coverage at a lower rate for my homeowners and a significantly lower rate for my auto insurance. I would highly recommend JAB Insurance to anyone.
