Our Practice

Care that feels personal.

We got into this work for the animals and stayed for the people who love them.

Every visit starts the same way — with time to listen, questions answered in plain language, and a plan that fits your pet and your life. No rushing, no jargon, and no decisions made for you.

Because we see many of our patients from their first vaccine through their senior years, we get to know the small things: which dog does better in a quiet room, which cat needs a slower approach, what normal looks like for your pet.

  • 30-minute appointments with room for your questions
  • Notes on every chart about what helps your pet stay calm
  • Clear recommendations and honest options
How We Practice

What We Offer

Clarksburg Animal Hospital offers complete care for every stage of your pet’s life.

A complete range of services for dogs and cats. Each service page covers what to expect, how to prepare, and what happens afterwards.

Preventive Care

Keeping them well — not just treating them when they aren’t.

The best appointments are the uneventful ones.

Regular exams, up-to-date vaccines and straightforward conversations about weight, teeth and mobility are what keep small things from turning into big ones. We’ll help you build a plan you can realistically keep up with — and we’ll tell you plainly when something can wait.

  • Vaccine plans matched to your pet’s lifestyle, not a one-size schedule
  • Guidance for each life stage, from puppy to senior
  • Appointments and records in the Pet Portal when you need them

Urgent Care

Something doesn’t seem right?

When your pet is unwell or injured, knowing where to turn matters. During office hours, call us first — we’ll talk through what you’re seeing, tell you what to do next, and be ready for you when you arrive.

  • Office hours: Mon–Fri 8am–6pm
  • Call ahead so we can prepare: 301-482-2535
  • After hours, VetTriage puts you on a video call with a licensed veterinarian, and Veterinary Referral Associates in Gaithersburg is open 24 hours.

What To Expect

A visit that makes sense to you and your pet.

Plain language, unhurried appointments, and decisions made together.

Experienced Veterinary Team

A veterinarian and technicians who have seen a great deal — and still take the time to explain it.

A local vet who came home to care for Montgomery County’s pets.

Before owning Clarksburg Animal Hospital, he honed his medical, dental and surgical skills on the veterinary staff of several area hospitals. His main goal is to keep pets healthy by emphasizing preventive medicine, and he is working toward board certification in Canine & Feline Practice.

In Their Words

What families tell us.

More from our clients

“The entire staff are incredible. I have rarely found a place where both my dog and I feel at ease entering. The techs are extremely friendly, and patient. When I first moved to the DCM, I was nervous to take my dog in as he was very skittish. Those fears were dispelled after witnessing the staff taking the time to make my dog feel comfortable before performing any exams.”

David Laydon Clarksburg Animal Hospital client

“I have always had a positive experience at Clarksburg Animal Hospital. Not only are the doctors extremely knowledgeable, they and the entire staff also are very kind and compassionate. When I had to put my dog to sleep because of increasing medical issues, they went out of their way to show their kindness and understanding, and that they cared not only for my dog but also for me and how difficult that decision was for me to make.”

Tina Blakeslee Clarksburg Animal Hospital client

“I have been taking my four legged babies to Clarksburg animal hospital for years. I had a really sick puppy and they called several times over the weekend to check on him. Just like family!!”
