Milton · North Fulton County, GA
Meet the vets who will be in the room with your pet.
A general practice for dogs and cats, run by two vets you can read about before you ever book — where they trained, what they treat, and what a first visit with each of them looks like. We tell you what a visit costs before you're in the room, and we're honest when the answer is a wellness plan is cheaper than paying per visit.

Why owners choose us
You are deciding who to trust, not comparing a price list.
You read about your vet before you book them
Dr. Marsh and Dr. Castellano each have their own page — where they trained, what they treat, and what to expect at a first visit. You're picking a person, not a time slot.
We price it before you're in the exam room
Wellness exams and vaccines are priced on this site. Anything that depends on what we find — surgery, a dental, an X-ray — gets a real number after we've seen your pet, not a guess over the phone.
Emergency answered in one look
Whether we can see your pet today, and exactly who to call when we can't, without digging through a phone tree while you're worried.
A wellness plan we can show you saves money
If your pet's a good fit for our wellness plan, we'll do the math with you against paying per visit — in writing, before you sign up for anything.
Is this urgent?
When to call today, not wait for an appointment.
We're not a 24-hour emergency hospital. If you're seeing any of the following, call (770) 555-0119 now rather than booking online.
When to call today, not schedule for next week
- Vomiting or diarrhea that hasn't stopped in 24 hours, especially in a puppy or kitten
- Straining to urinate, or not urinating at all — this is a same-day call for male cats specifically
- A limp that showed up suddenly, or any refusal to put weight on a leg
- Swelling around the face or hives after being outside or eating something new
- A cut or wound deep enough to see fat or muscle, or bleeding that hasn't slowed after ten minutes of pressure
- Not eating for more than 24 hours, or noticeably more tired than normal for more than a day
What we do
Wellness, surgery, dental and diagnostics — for dogs and cats.
Wellness & Prevention
Wellness Exams
From $55A nose-to-tail check twice a year for most pets, so we catch what's changing before it becomes an emergency visit.
Vaccinations
From $25 per vaccineCore and lifestyle vaccines scheduled around what your pet does — a dog who boards or hikes needs a different schedule than one who stays home.
Parasite Prevention
From $15/monthYear-round flea, tick and heartworm prevention — Georgia summers don't give fleas an off-season, so neither do we.
Surgery & Dental
Spay & Neuter
Quoted at your pet's wellness examPriced after we've seen your pet, not off a phone estimate — weight and age both change what the surgery and recovery need.
Dental Cleaning & Oral Care
From $350, based on pre-anesthetic bloodworkA cleaning under anesthesia with bloodwork first, because we want to know your pet can handle the anesthesia before we schedule it, not after.
Diagnostics
In-House Lab & Bloodwork
From $85Same-visit results for most bloodwork, so a sick-pet appointment usually ends with an answer, not a callback in three days.
Digital X-Ray & Ultrasound
Quoted after examImaging done here, read by one of our own vets first — a specialist referral still happens when a case genuinely needs one, not as the default.
Additional Care
Microchipping
$45Ten minutes, done at any wellness visit — the most common reason a lost pet doesn't make it home is not having one.
Short-Stay Boarding
From $38/nightA small number of runs for clients already in our care — not a boarding facility, so we keep this to pets we already know.

How the wellness plan works“A checklist can tell you your dog is due for a vaccine. It can't tell you whether the vet giving it will still be here next year.”

What people say afterwards.
4.8from 236 reviews on Google
“I called three places about my cat straining to pee and Wrenfield was the only one who told me on the phone that it was a same-day thing, not a next-week thing. Dr. Castellano saw us within the hour.”
Renee K.
Same-day urgent visit, Milton
“Dr. Marsh talked me out of a dental he didn't think my 13-year-old lab needed yet, and told me exactly what to watch for instead. That's the opposite of what I expected walking in.”
Tom A.
Senior pet wellness exam, Alpharetta
“We put both cats on the wellness plan after Bianca ran the numbers with us and it was genuinely cheaper than what we'd been paying per visit. Nobody upsold us on it.”
