★★★★★ The staff at Companion is friendly and caring from the front desk to the vet techs to the doctors. They do extra things to make you feel special, like having white boards welcoming our pets by name in the rooms to sending personalized follow up emails. They even have a candle at the front desk that they will “light” to request people be quiet and respectful as someone is saying goodbye to their beloved pet in the back.
