Welcome to Allen Veterinary Hospital

Pet Emergency? Call us right away at 972-727-8383!


This year we have seen a large increase in our products due to supply chain issues.  We have received multiple letters throughout December 2021 preparing us of these increases.  We have no choice but to increase our costs to continue to provide the best possible care for your beloved pets.  Sorry for any inconvenience this may cause you as pet owners.  Price increase will go in to effect January 2022.

Covid19 policy:

Please come inside and check in for your appointment.  You may then choose to wait in your car or in the lobby.  A Technician will call you when your exam room is available.  We ask that you limit the amount of family members you bring with you to our hospital (our ideal situation would be 1 owner per pet).  We are cleaning/disinfecting rooms and lobby multiple times a day for yours and our staffs safety.

About Our Company

Allen Veterinary Hospital opened its doors in January, 1986. Dr. Mike Overton founded the hospital in order to meet the small animal needs of Allen, Texas. Dr. Alan Coffman, a 16 year employee of the hospital, purchased the practice upon Dr. Overton's retirement in 2010, in order to continue exceptional service and reputation of Allen Veterinary Hosptial. Since then, it has grown to include three full-time veterinarians, one consultant veterinarian, and a staff of more than 24. We treat all sorts of companion animals with special emphasis in dogs and cats. Two clinic cats roam the premises making sure that everyone feels at home, kept company by five birds, one ferret (Sid), and an aquarium full of fish.

Allen Veterinary Hospital has been awarded The People's Choice Award for Best Veterinary Practice in Collin County every year beginning from 2010, a proud streak that we don't want to have end.  Dr. Alan Coffman was recognized by The Texas Animal Control Association and received the W.R.

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!"
