Ben Moore

Ben Moore is Chief Product Officer at PerfectServe.

Upon PerfectServe’s acquisition of Telmediq to consolidate the forces behind the industry’s most comprehensive CC&C platforms, Moore joined the combined company’s leadership team and has played a vital role in the integration process.

Telmediq’s roots can be traced to a 2010 hospital stay for Moore’s wife and newborn daughter that introduced him to a strange dichotomy: physicians wrestling with pagers and playing telephone tag while their patients used state-of-the-art iPads. He saw a prime opportunity to improve the cumbersome state of healthcare communications and, ultimately, patient outcomes. Telmediq was founded soon thereafter, and Moore launched the service in early 2012.
