Verizon continues to leak executives as long-time networking technology executive Nicola Palmer said she would be retiring from the telecom operator she has worked at for 33 years.

In a LinkedIn post, Palmer announced she would be retiring in July, and touted her experience at the operator.

“It is rare these days to find that kind of career longevity with a single company, but I found it with Verizon,” Palmer wrote. “I know what kept me here all these years … it was the opportunity to continuously learn and grow and work alongside the most talented people to bring the best technology to life with purpose. I feel lucky and extremely grateful for this front row seat during the rise of the digital age.”

(Palmer also includes a pretty cool video that’s definitely worth watching.)
