Chris Gillard

Executive Hospital Laboratories Operations Manager

Bio summary follows:

Pathology is not generally known for its face paced, energetic style. However, in a hospital environment, that’s exactly what is needed. It’s the difference between a patient living and dying. It’s not speed that is the most important factor. In these instances, it’s a quick settled mind and a steady, assured, consistent pace which embraces accuracy, thoroughness, and attention to detail. It’s also as simple as knowing the right blood group and who to call to get that product.

Chris started out as a Technical Assistant (TA) in 2009. However, now under Chris’ operational charter includes all hospital employees, all hospital shifts and workloads from oncology and chemotherapy services all needing accurate results in exceptionally short timeframes.
