Services
Pet Wellness Exams
Our comprehensive wellness exams detect early signs of illness through head-to-tail evaluations. Using advanced diagnostics, we monitor weight, dental health, and chronic conditions to create preventive care plans. These exams ensure pets maintain optimal health throughout their lives while addressing owner concerns.
Pet Surgery
Our laser surgery technology offers minimally invasive treatment options with reduced recovery times. The precision of laser light interacting with tissue improves outcomes for soft tissue procedures. We combine surgical expertise with postoperative monitoring to ensure patient comfort during recovery.
Diagnostic Services
Digital radiography and dental X-ray equipment provide high-resolution internal imaging for accurate diagnoses. Our in-house laboratory enables rapid bloodwork and pathology analysis. This technology allows immediate assessment of injuries, chronic diseases, and dental abnormalities requiring intervention.
Euthanasia Services
We offer compassionate euthanasia services prioritizing patient comfort and owner closure. Our private consultation space accommodates memorial moments while cremation options respect individual preferences. The team focuses on creating peaceful final experiences aligned with each family's needs during emotional times.
Pet Dental Care
Preventive dental care includes professional cleanings, periodontal assessments, and home care education. Dental X-rays identify hidden oral issues beneath the gumline. We emphasize the critical connection between oral health and systemic wellness to prolong pets' lifespans through improved dental maintenance.

We love Dr. Flahaven and the staff at Deer Grove! Dr. Flahaven has been so wonderful to both of my dogs my one who passed and our newest family member. When my Charlie was getting to the end of his life and was often sick he did so much to help us and made time to fit us in to ensure Charlie was taken care of. I recommend Deer Grove to anyone who asks me!

Dr. Mark is a great person and an amazing doctor to my puppy Groot! Groot has had a rough first year with his health, and Dr. Mark is always available to treat him. He has accepted us emergent post 6 pm walk-ins and stayed late to treat our puppy more than once. As new pet parents he takes the time to guide us so that we can keep Groot healthy. His clinic and staff are always available in times of emergency. Our calls are always returned in a timely fashion. We trust Dr. Mark with our puppy and feel so lucky to have found him!

when they kill your dog. They killed my familys puppy. She was going in for her first shots and they never warned us of warning signs or what to do when we saw them. We called them as soon as we noticed a couple hours later but they were closed by then. Her death could have been prevented and the doctor admitted that he was negligent when he spoke to us the next day after we informed him
she died. We had wanted some recognition and to inform him that these vaccines might hurt another puppy as well. Due to his negligence he said he would give us the vet service free
