Pasadena-founded MSP that grew from LA break-fix into a national provider

Arcadia doesn't yet have a headquartered VoIP & UCaaS team on our list, so we've surfaced 0 providers based in adjacent neighborhoods who actively support Arcadia clients. Arcadia's healthcare and hospitality mix drives HIPAA and PCI-aware stacks with 24×7 support windows. For VoIP & UCaaS engagements specifically, porting timelines and E911 configuration are the two most common go-live risks, and buyers typically flag call-quality QoS on shared broadband as the first-quarter priority. Because Arcadia indexes toward Healthcare, expect proposals to reference those industries by name.
