Who we are

---

A childhood in a plumbing shop and 75 year legacy of plumbers before him lead our President and Founder, Yosef "Yosee" Kreitenberg to where Chalk Mountain is today. Yosee is a fourth generation plumber with a construction foundation like no other. By the age of 20 years old, Yosee already acquired a bachelors degree and a C-36 plumbing license. Despite his relatively young age, his knowledge and understanding of the trade and business goes unmatched. Yosee's passion and pride in his work makes Chalk Mountain a wonder to work with. 

Rachel, Yosee's wife and co-founder of Chalk Mountain is one of the most talented women in the business. Rachel has many years of experience in the construction industry, working in accounting, payroll, billing, and expenses. Her years of experience and naturally gifted talents make her a very valuable member of our team.  

Yosee's father, Ephraim "Fry" Kreitenberg and his mother Shaindee, currently own and operate a successful union plumbing and mechanical shop called "Kreit Mechanical". Yosef's Grandfather, Harvey Kreitenberg, sits as the Chairman of the Code technical advisory committee, he is a plumbing and mechanical engineer, plumbing and mechanical inspector, and licensed contractor in California and Nevada in class B-1, C-1, C-16, C-20, C-36, and C-42. Harvey, Ephraim, and Shaindee all advise and assist in the operation of Chalk Mountain Mechanical, through pre-construction, design, and day to day operations. Yosef's great grandfather, Sam Kreitenberg, joined the plumbers union after escaping from war-torn Europe. In 1956 sam and his wife Irene started their own shop, calling it "Kreit Plumbing company" beginning the Kreitenberg legacy.
