Customer Project Review

I found Gene’s website online after getting little-to-no response from local pool builders to renovate a dilapidated 1940’s pool and add an in-ground spa.

After reading Gene’s book and watching his videos, I convinced myself I could do the work myself.  Gene’s assistance in the design, equipment order, and support through the building process was paramount to success and second-to-none; it was like having somebody on site.

I highly recommend Gene’s design guides, and can’t emphasize enough how thorough his support was… he was there every step of the way.
