Serena Bakestress in the last week

BEST EXPERIENCE EVER. I brought my cat-son in very worried it was a medical emergency. They were so empathetic and acted with urgency. I could feel they truly cared, regardless of it being our first time there. Everyone was very knowlegdable and thorough, going above and beyond for my cat. By the end of our office visit, with the extent and quality of care- I was shocked at how affordable they made it. A few days later they reached out to make sure everything was okay still... Highly recommend!
