Judy Jyi-
Dog Walker - Pack Leader

Judy Jyi is a fast learner, has high energy, a positive upbeat attitude and is retired. She has a great deal of patience and can stay calm in stressful situations due to her management background as an engineer. 

"My family moved from Louisiana to Martinez in 2008.  I worked as a project engineer in the petrochemical industry for over 30 years.  I was familiar with working under stress and was able to juggle multiple projects at the same time.  I was the person that management likes to assign difficult and fast track projects. My track record showed I was reliable and took responsibility for my project group. Because I have worked in the refinery for many years, I take safety very seriously.  I will ensure the dogs are walking in a safe and pleasant environment. I love to travel and enjoy walking in the beautiful Bay Area.  I retired from my engineering job in 2020.  Currently, I walk about 3 hours every day."  - Judy Jyi
