Johnna RVT, Practice Manager
Johnna is a Registered Veterinary Nurse. She has been with Irvine Pet Complex since 2018. Her training in veterinary technology occurred at Mount San Antonio College in Walnut, California. Her passion for leadership naturally put her in the positon for our practice manager. She is dedicated to her staff and all of our patients.
Johnna has a wild side that many are unaware of. Besides her love of four legged creatures, she worked at the Big Bear Alpine Zoo rehabilitating raptors and preparing them for release back into nature. One of her personal triumphs was working on an osprey that others had given up on believing that it was unable to fly. Johnna successfully nursed it back to being a free flying bird.
With a last name of Sierra, it is only natural that she loves spending her free time in nature. You can find her hitting the trails on horseback, backpacking or hiking with her canine companion, Pennie.
