The Team

Eddy Alonso
Co-Founder
Plumbing isn’t just a job for the Alonso family — it’s a legacy. Julio Jr. and Eddy are third-generation plumbers who grew up watching their father and grandfather work the trade. Long before they ever picked up a wrench professionally, they were already learning the skills, techniques, and work ethic that only decades of hands-on experience can teach.
When the time came to build something of their own, they had the best mentors imaginable guiding them every step of the way. Today, Alonso Plumbing Inc. is the result of three generations of knowledge, dedication, and an uncompromising commitment to doing the job right.
That experience shows in the work. From large-scale resort plumbing remodels to ADU builds and new construction projects, the Alonso team has the expertise to handle jobs of any size and complexity — always on time, always up to code, and always with the same family values that started it all.
