Hi, my name is Brian Smith. I have recently started a water treatment company, H2O IN THE 603 WATER TREATMENT LLC, which services Southern New Hampshire. I am not new to the industry; I bring over 20 years of experience.

I began doing rough plumbing residentially and found I had an interest in and knack for water filtration installation and services. This interest became a passion for water treatment. My first plunge into the business was with Culligan of N.H. I was with them for approximately ten years and did all levels of service and whole system installations.

Next, I wanted to learn more about Radon in water, which was the catalyst for my next endeavor in 2015 with Advanced Radon Mitigation. I began as a Service Technician, doing service, installations, and sales & was ultimately promoted to Service Manager. It was a great experience, but I recently realized that I wanted to take my passion for water treatment to the next level.

So, with that, I took my final plunge (along with a leap of faith) and launched H2O IN THE 603 WATER TREATMENT LLC.
