Meet Our Vet Techs

Veterinary nurses provide many important services to our patients including: pre- and post surgical care, monitoring symptoms, administering medications, alerting the doctors to any problems, and giving lots of hugs to frightened animals.


Renee Small, L.V.T.

My name is Renee and have been working here since 1990 as an assistant receptionist and then I graduated from NOVA in 1998 and became a Licensed Veterinary Technician.  I love all animals and enjoy the opportunity to work with not only cats and dogs, but exotics such as birds, reptiles, ferrets, rabbits, guinea pigs, and pocket pets.  My areas of interest include dentistry, anesthesia, and pain management.  I enjoy educating clients about behavior, diet, and geriatric care.

I live in Nokesville with my husband and two boys on our Teeny Tiny Small Farm with an array of rescue pets, dogs, cats, rabbits, guinea pigs, goats, pot belly pigs, donkeys, chickens, a turkey, and a turtle.  We also board dogs and often have many visitors.  They love staying at the farm!


Denise Sanchez, L.V.T.

I started working at GFAH in fall of 2000 as a veterinary assistant. In 2002 I graduated from NOVA and became a licensed veterinary technician. I currently live in Manassas with my husband, Juan, who used to work here as a receptionist. We have two cats, both adopted through here, named Eli (yes, named after Eli Manning, go Giants), and Peyton, and a French bulldog, Cooper. We have all the Manning brothers.

When not working I’m probably traveling.  My goal is to see all 50 states.  Each year we try to see at least one new state.  I’ve been to Guatemala twice, with hopes of going more, to help the local people achieve better living conditions.


Beth Lannon, L.V.T.

I joined Great Falls Animal Hospital in April, 2000.  I worked as a Veterinary Assistant for five years before deciding to go back to school and get my Technician’s License.  Prior to GFAH I spent sixteen years working with computers in “corporate America.”  I have a degree in computer programming.  In the 70’s I was a social worker for a government agency.

In 2012 I got my license to rehab wildlife in Virginia.  This can be a very rewarding job or extremely frustrating because well-meaning people frequently think baby animals are orphaned and in reed of rescuing.  I can’t stress enough that baby birds, squirrels, bunnies, etc. frequently leave their nest before they are ready to be on their own.  It is usually better to leave them alone as the parents do a much better job at raising animal babies than people.  Rehabbers quickly become overwhelmed with trying to care for the 100’s of babies rescued by the public.  If you are interested in learning more about wildlife I suggest joining the Wildlife Rescue League of Northern Virginia.

My desire to help in time of crisis led me to join several animal rescue groups, including the Humane Society of the United States (HSUS) outreach program fro Veterinary Technicians, the National Veterinary Response Team, and The Veterinary Medical Response Team.  The most memorable adventure of my life was going to Louisiana where I helped provide medical treatment for the thousands of displaced animals from Hurricane Katrina.

I live with my tow cats, Sam and Rosie (adopted through GFAH’s adoption program) in Reston, VA.


Mary Portelly, L.V.T.

After 20 years working as a Software Engineer for various Telecom companies, I decided it was time to do something I feel passionately about… so I went back to school to become a Veterinary Technician and graduated in May 2007.

I started working at GFAH in February 2006 and completed my internship in the summer of 2006.  I love being part of the GFAH team and enjoy the constant variety of patients we get to treat.

I was born in England and moved to this country in 1988.  I live in Reston with my husband, Ken, and our dogs, AnnieBelle (a sweet St. Bernard mix) and Clyde (one-eyed beagle).  In my spare time, I enjoy volunteering fro animal welfare organizations to help homeless dogs, swimming, and taking AnnieBelle to visit the residents of a local nursing home (she is a certified therapy dog).


Cara Scarano, L.V.T.

I started here in 2005 as a veterinary assistant and was inspired to further my education. I attended NOVA and graduated in 2010 as a Licensed Veterinary Technician. This position has given me new roles and responsibilities which I truly enjoy. My main areas of interest include low stress handling, behavior, and pain management. I am a member of the International Veterinary Pain Management Association and I truly believe we can strengthen the human-animal bond thru compassion and understanding.

In my free time, I enjoy being outdoors whether on land or in water. My husband, Jesse, and I recently adopted a Miniature  Poodle, Chester, and enjoy exploring our local trails and waterways. We also share our home & hearts with two kitties, Rod and Todd, whom I adopted from GFAH. When I’m not outside playing, I can be found relaxing with good food and good friends.
