General Partner
Hard working, detailed, conscientious, accommodating, professional, kind, and friendly. He was hired by Vivint Solar to repair our water damaged ceiling. He went the extra distance to check the repairs to our roof and found that Vivint’s repair still leaked. He repaired both the roof and the ceiling! His repairs are perfect. We are pleased to have found someone we can trust.
