    Practice Owner


    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).

    When not taking care of our furry friends at Cross Timbers AMC, Dr. Harvey enjoys spending time with his family, golfing, hiking, reading and college football (Go Gators!).  Dr. Harvey is also active in the community in the following ways:

    Associate DVM

    Dr. Lock was born in Minnesota, and while growing up, lived in Michigan, Wisconsin, Nevada, Texas and Tennessee.  She received her degree from the University of Tennessee in 2002.  This is where her love of college football and most importantly, the Tennessee Volunteers began.

    Another love became apparent at the University of Tennessee. Feline Medicine.  After graduation, she worked for 2 years with a nationally recognized feline practitioner in San Antonio, Texas, prior to joining Cross Timbers AMC in 2005.  She truly enjoys that this has allowed the diversity of getting to work with dogs, in addition to being able to continue her passionate care for cats.  She is working toward becoming ABVP (American Board of Veterinary Practitioners) certified in feline medicine in the future.  She is a USDA accredited  veterinarian and has experience in and enjoys the challenges of helping clients who are traveling or moving overseas with their pets.

    Travel is another love of Dr.Lock's.  Her husband, Bevin is from the beautiful country of New Zealand and they try to get home to visit their family as often as possible.  Dr. Lock is blessed that they have her immediate family here locally.  She and her husband, along with their dog Peyton (yes, after Peyton Manning) and their many beloved felines enjoy living in the Highland Village community. She enjoys working with patients, clients and the staff, all of whom she considers her extended family at Cross Timbers AMC.

  • O'hana and "Big Dog" Daphne


    CT-AMC team Members

    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.
