Case Study: Knee Walker Central achieves national growth and remote-work flexibility with Vonage

Growing a Business with a Phone System that Scales

Knee Walker Central, founded by Mark Krassner, manufactures, rents and sells a knee‑walker mobility device and relies on phone sales for more than 75% of its revenue. To protect that income stream and support tightly coordinated customer service and operations, Krassner needed a dependable, scalable business phone system that would also enable the remote workforce he planned to build.

Vonage’s hosted VoIP solution — with virtual receptionist, call queuing, call recording, reporting/analytics and a “work from anywhere” admin portal — gave Knee Walker Central the reliability and tools it needed. The result: national growth, a decentralized hiring model that improved recruiting and employee work/life balance, stronger customer service through coaching and analytics, and reduced risk of lost calls and revenue.
