"I love Middlesex veterinary center! I own three dogs and a cat, and they've always provided amazing care and respected my input. Unlike most vets, they don't immediately suggest the most expensive option. The staff is friendly, making my pets feel welcomed and loved. After years of taking my pets there, I trust their knowledge and am extremely happy with their care "

"What a dedicated and caring staff! Everyone from the front desk staff, vet techs, and Dr. Mockler took excellent care of our dog in an emergency situation. We all felt immediately more at ease and couldn’t be more grateful for their expertise and willingness to help in a crisis. Thank you!"

"When I called to say my dog had vomited and had loose feces, I got an immediate appointment. Everyone very sweet to Karma despite the fact she was barking her head off. The doctor asked my opinion about giving her a shot, but I demurred. She was given some medicine with instructions and I received a call the next morning. She seems fine now and I am thrilled that her problem was taken seriously."
- Marla R
"Dr. Mockler is a very pleasant and patient veterinarian, with lots of knowledge. She always takes time to answer all of our questions without rushing us. I would highly recommend her to anyone who is looking for a veterinarian.!"
