Who better to tell you about us than our clients?

“…I have the confidence knowing that my insurance is being handled by trusted professionals.”

"When I started my backflow testing business I had zero clients, so I needed to get on to the approved testers lists in our area. I couldnt do it without the proper insurance policy. Nick and the Dahlmeier Team took the time to research my best options and got me the proper coverage at the right price. Four years later my customer base has grown steadily and I have the confidence of knowing that my insurance is being handled by trusted professionals."

“Thanks to Nick, I can concentrate on my business…”

"I had been carrying liability insurance for years with one company, but they just weren’t able to provide the level of service I needed to remain competitive and grow my business. My previous agent was unable to satisfy the needs of my backflow testing business, as more of my clients were requiring very specific wording on certificates. Nick Mariottini was able to discuss the details directly with my clients and then worked with his underwriters to obtain the correct wording, helping me secure some very valuable contracts. Thanks to Nick, I can concentrate on my business, knowing my insurance needs are taken care of."


John Graham, Graham Backflow Services, Forest Ranch, CA




I've been a tester for over 20 years and have never really needed a lot of insurance certificates and found most of the insurance policies in the past to be very expensive and outside of my budget. So when Nick contacted me about his program I was a bit skeptical, but decided to get a quote anyways. To my surprise the coverage was not only more comprehensive than anything I had seen in the past, but also more affordable. The folks at Dahlmeier have even been able to save me money on my homeowners and auto insurance!

Bob Condos, President, Impact Media Group, Inc.
As an owner of multiple income properties here in Northern California, for years I had dealt with a patchwork of different insurance companies. About three years ago I challenged each of my agents to provide an estimate for bundling all of my insurance needs, including my homeowner's and auto policies. Pam Hester at Dahlmeier Insurance Agency gave me a quote through Grange Insurance that was lower by far than the others, resulting in savings of several hundred dollars per year. But it’s more than saving money. The insurance side of my business has been simplified, and I enjoy the personal, friendly service I receive whenever I decide to drop by in person, whether it's to ask a question, request a document, or make a payment. Thanks Pam, and thanks to Dahlmeier Insurance.

Dahlmeier Insurance has provided us with alternatives to the normal, plain vanilla coverage. They provided us with a fresh set of eyes to look at what we have in terms of coverage, and they tell us what else is out there that may better fit our needs. Specifically Dahlmeier Insurance worked with us to secure a Workers Comp plan that has been a game changer. We had been absorbing 20% increases each year while lowering our accident and claims exposure. Dahlmeier Insurance introduced a program that allowed us to share some risk while lowering our premium. We knew we could control our safety exposure, what we needed was a partner to allow us to prove ourselves. Dahlmeier Insurance to secure us a multi-year contract that has saved us money, and tied OUR safety program to OUR Workers Comp cost.
