CHIEF EXECUTIVE & PRESIDENT
Ericson Tua 'one, Founder of Ber Wilson understands what separates men from leaders: mission-critical infrastructure is built by men of unwavering character willing to carry full responsibility.
When federal agencies bring fiber and broadband to forgotten communities, when networks must perform without failure, when families depend on infrastructure that endures, the outcome rests on the man leading the work.

Pacific Islander values such as caring with respect and reverence. Honor and collective strength. The duty to serve with integrity & that Christian faith that service transcends profit.
Work begins before dawn and continues until finished. There are no shortcuts. A man's word is his bond. Integrity under pressure determines everything.
The work gets done right, or it does not get done. Tua'one is a Licensed General Contractor licensing with General Building B100, Engineering 100, and S350 HVAC credentials, Tua 'one brings tradesman's knowledge and technical discipline as well as Technology
