"Genuinely cares"

I was so impressed with Dr Rainer and his staff.  I believe he genuinely cares about each and every one of his patients.  He was so gentle with my Gilli and so efficient.

Loving Care

During a routine dental cleaning, Dr. Rainer discovered a mass in my German shepherd's soft palate. After discovering that it was oral melanoma, Dr. Rainer and the entire staff walked every step of our cancer journey...After eleven and one-half months, Tiberius's journey ended with the same amount of loving care.

Dr Rainer and staff are amazing. Always willing to answer my questions and address my concerns with my pets. Prescriptions are filled promptly, emails answered immediately and the vets always return my calls.
