We’ve Moved!

Allen Veterinary Hospital is excited to announce that we’ve officially moved into our brand-new facility at 851 E. Main St. in Allen! After serving the community from our previous location since 1986, we’re thrilled to continue providing the same hometown care in a larger, more modern space. 

Our new facility includes 14 exam rooms, a bigger waiting area, and improved parking to make your visit even more comfortable. We look forward to welcoming both familiar and new faces and continuing to care for your pets for years to come!


About Allen Veterinary Hospital

Founded in January 1986 by Dr. Mike Overton, Allen Veterinary Hospital has been a trusted part of the Allen, Texas community, providing exceptional care for small animals. In 2010, after 16 years as part of the team, Dr. Alan Coffman proudly took over the practice upon Dr. Overton’s retirement, ensuring the hospital’s tradition of top-quality care continued. Today, we’ve grown to include three full-time veterinarians, one consultant veterinarian, and a dedicated staff of more than 24, with a special focus on treating dogs and cats.

We are honored to have received the People's Choice Award for Best Veterinary Practice in Collin County every year since 2010—a streak we are committed to upholding. Dr. Alan Coffman was also recognized by the Texas Animal Control Association with the prestigious W.R. Bilderback, DVM Award for outstanding service to the animal control profession in Texas.

In addition to our work with pets, Allen Veterinary Hospital is proud to support the local community. We are long-time sponsors of Allen Eagles High School (football, baseball, basketball, golf, and performing arts) and the Allen Americans hockey team, multiple-time Presidents Cup and Kelly Cup champions!

At Allen Veterinary Hospital, we treat your pets like the cherished family members they truly are.

Read What Our Clients Say

  • "Had Harper’s right paw checked, as she holds it up when she sits. Dr. examined and said everything looked good but did an X-ray to be sure. FOR FREE!!! Harper is just fine and either has phantom pains, remembers the procedure and is scared/scarred, or just doesn’t like her paws squeezed."
    Ashlee E.
  • "Truly love this vet! The only reason we have the pets we do (dog, ferrets, rats) is because we know this clinic will care for them without robbing us. So so so thankful! Dr. Mac, you are a jewel! This mama could not have made it without your calm and capable demeanor!"
