Dr. Harvey was born in Metairie, Louisiana. He received his degree from the University of Florida College of Veterinary Medicine in 1998. Dr. Harvey began his veterinary career in the U.S. Army, serving as Chief Veterinarian at Redstone Arsenal in Huntsville, Alabama. He then joined a small animal hospital in 2001, serving as Associate Veterinarian, in Lake Mary, Florida.
Dr. Harvey and his wife, Christine, excitedly discovered beautiful Flower Mound after a long search. They purchased Cross Timbers Animal Medical Center (formerly Aladdin Animal Hospital) to realize Dr. Harvey’s dream of practice ownership. Each and every day, the primary goal of Dr. Harvey and his staff at CT-AMC is to provide the most personalized and highest quality health care to each pet in our animal hospital family!
In addition to the practice, Flower Mound is exactly the community that the Harveys were seeking to put down strong family roots for years to come. Dr. Harvey and Christine have three children. There have been many pet family members through the years; including, beloved Rogue and Smokey, the couple’s college cats; sweet Casey Dog, a black and tan coonhound adopted from Redstone in Alabama; and many rescue animals that completed the family.
Currently, the family is blessed with lots of unconditional love from O’hana, a sweet and beautiful mixed breed dog from Coppell Humane Society, and Daphne, an amazing Pyrenees dog and true companion to O’hana and the Harvey family, from SPIN (Saving Pyrs in Need).

O’hana & Big Dog Daphne
Cross Timbers AMC Family Dogs
O’hana and Big Dog are the Cross Timbers AMC adopted family dogs. They live with the Harvey family, happy to have found a forever home where they chase squirrels and geckos to their heart’s content. In addition to bringing joy to the Harveys, they love occasionally visiting their Cross Timbers family for Doggie Camp where they’re showered with lots of TLC.
O’hana’s specialty is chasing full speed after tennis balls and bathing loved ones in kisses. She joined the Cross Timbers AMC family in July, 2008.
Daphne’s specialty is being O’hana’s Best Friend and giving lots of love to the Harveys. She’s especially watchful over the kiddos, which they love! Daphne is affectionately called “Big Dog” for obvious reasons, but this nickname also describes the big love in this sweet girl’s heart.
On a personal note, O’hana means “Family” in Hawaiian. Her name was suggested by then five-year-old Christopher, while a big fan of Disney’s Lilo & Stitch. When O’hana was adopted, he said, “Her name means family, and family means no one gets left behind.”
Cross Timbers Animal Medical Center asks you to responsibly consider adopting or fostering if there is a little extra space under your roof for a lot more love from an animal companion. We think you’ll find the rewards are never ending. It’s one way you can help make the world a better place, by making the life of an animal a happier one.
