Dr. Greg Matt grew up in a small town in Iowa and was inspired to become a veterinarian by the care and compassion displayed by his family’s veterinarian. 

Following graduation from Iowa State University then Iowa State University School of Veterinary Medicine with his D.V.M., he joined a busy practice in Dallas, Texas with a large caseload. There he developed extensive experience in internal medicine and surgery. In 1985 he moved to Houston, Texas purchasing Mt. Houston Animal Clinic in north Houston. Then in 1996 he purchased Beechnut Animal Clinic located in southwest Houston.

Dr. Matt strongly believes in staying current in the ever-changing world of veterinary medicine, and continues to practice on the leading edge- whether it be medical protocol, pharmacology or technology .He particularly enjoys tackling difficult to diagnose cases and is always searching for new technology to support his growing staff of doctors.

In Dr. Matts’ own words “The most rewarding aspect of having practices with multiple doctors is you get to surround yourself and work with incredibly intelligent, compassionate, and talented people. I honestly feel honored that they have chosen to work with me.”

When he finally gets a chance to relax you can find him ocean kayaking, boating, playing electric guitar, scuba diving or building computers.

The family pets are Champ a local shelter dog, and Chanel the cat. On a regular basis there is an extra golden retriever hanging out with the gang. The Matt’s are a foster home for the Golden Beginnings Golden Retriever Rescue Group

Dr. Patty Grana spent her early years in the beautiful Arizona desert. After a Master’s degree in International Business (including studying many languages and becoming proficient in Spanish), she went on to have a successful career in the Los Angeles film industry.After many years, though, the itch to pursue her life-long veterinary dream could not be ignored! She made a drastic right turn in her career, attended veterinary school at Texas A&M, and hasn’t looked back since. It has been the best decision of her life!

As a veterinarian, Dr. Grana treats not only dogs and cats, but exotic pets as well.  She likes the challenge of a canine or feline dermatology case as well as doing a rabbit spay or neuter!  She is a well rounded and passionate veterinarian who values the bond between owner and veterinarian.  She’s very interested in exotic animal medicine (reptile, pocket pet and avian) and has spent many extra hours perfecting her exotic medicine.  She realizes that the communication bond and client education between you and her is vital for successful care of your pet,  no matter the species!

At home, Patty and her teenage (ice hockey playing) son own several pets that keep her busy: dogs, cats and cockatiels. 

In her time away from the clinic, Dr. Grana enjoys horseback riding,reading, and traveling. She’s traveled through Europe, Asia and Central America, and has even sailed around the world ona ship! Her motto: “Have passport, will travel!”
