Meet Our Team

Sue Lee Mace, DVM


Hello, I am Dr. Mace, and welcome to Vetsavers. It has been my absolute dream to provide the best quality veterinary care at a price that is truly affordable. We are fortunate to be able to provide a wonderfully modern, clean, state of the art facility where pets get the best quality veterinary care they deserve.

After working 12 years in marketing, I returned to school and achieved my lifelong dream of becoming a veterinarian. I graduated from the Texas A&M University, College of Veterinary Medicine in 2006 – truly one of the happiest days of my life! I feel privileged that every day I can care for pets that bring so much joy to people’s lives. To aid the community, I volunteer with local shelters, and rescue groups. I practice compassionate medicine and care deeply for my patients and their pet parents. I look forward to meeting you and your beloved pets!

Jeffrey Stillie, DVM

Dr. Stillie

Hello! My name is Dr. Jeffrey Stillie and I am delighted to be on the team at Vetsavers Pet Hospital.

I have always had a love for animals and wanted to make a positive difference in their lives. At the age of four, I chose my veterinary career path and never once second guessed this decision. I attended Kansas State University for both my undergraduate and professional studies and in May of 2002, received my Doctorate of Veterinary Medicine. Upon graduation, I moved to Ohio where I worked as an associate veterinarian at a high quality practice. Wanting to be closer to family, I relocated to the North Texas area in 2004 and have been here since.

I am a very compassionate and dedicated veterinarian and a member of the local, state, and national veterinary medical associations. I enjoy all aspects of veterinary medicine but have a special interest in preventive and geriatric medicine.

When not at Vetsavers Pet Hospital, I enjoy family time with my wife (who is also a veterinarian) and son. My recreational activities include hiking, camping, and caring for our menagerie of pets

Rebecca Jones, DVM

Dr. Jones DVM

Hi – my name is Dr. Jones and I am excited to join the Vetsavers Pet Hospital team!
I come from an Air Force family and have lived all over in my lifetime (Texas, Hawaii, Spain, Georgia, and Oklahoma). I received a bachelor’s degree in Zoology/Biomedical Sciences at the University of Oklahoma and then my doctorate in veterinary medicine at Oklahoma State University in 2011. I then completed a one-year small animal referral and emergency internship in Maryland before returning to my birth state Texas to pursue small animal general practice, with a special interest in small animal internal medicine and radiology. Finally I’m home!

As part of a multi-pet household myself (Have you met Melon my Pomeranian? He is often at work with me!), I am so happy to be a part of a hospital where we can pursue the best quality medicine while still remaining affordable to our clients.

In my spare time, I love knitting, hand spinning yarns, and general crafting/creating and also enjoy contributing to Vetsavers’ Facebook page.

I can’t wait to meet you and your pawed family members at Vetsavers Pet Hospital!

Amanda Machen, CVT and Operations Manager


Hi! My name is Amanda and I am the lead technician and Operations Manager at Vetsavers Pet Hospital. Growing up in a family full of animal lovers it is no surprise I chose helping pets as my life long profession. I have been a Certified Veterinary Technician for 16 years and can’t imagine doing any other job.

When I was a child we had quite the variety of animals come through our house. We raised pigs, cows, ducks, chickens, squirrels, raccoons, kittens, puppies, birds, reptiles and more. I was also in Future Farmers of America while in high school. Speaking of high school, that is where I met my husband. We have been together almost 15 years, married for 6 years. My animal family includes 3 dogs (Libby Lou, Coconut and Symon), 3 cats (RoxZee, Ringo and Starr), a bearded dragon named Pete and several fish.

Outside of animals I also enjoy time with family and friends, cooking, baking, muscle cars, music, baseball and hockey. Go Texas Rangers!

I am so glad to be a part of this wonderful team of fellow animal lovers at Vetsavers Pet Hospital. I am looking forward to helping the animal rescue community and educating clients on how to take care of their pets. Most importantly I am thrilled that we are able to offer such affordable pricing so that everyone is able to take the proper care that each animal deserves. It is very rewarding to be able to do something you love and also be able to make a difference in the lives of the deserving pets.

Hi! My name is Lynette. I grew up on a farm in South Dakota and was in 4-H for 10 years, so I guess that is where my love for animals began. I moved to Texas in 1981 with my 3 loving children – Jackie, Matthew, Allison and since then have been blessed with 2 beautiful granddaughters, Madison and Jade and my fur baby Sammy.

I began fostering dogs 7 years ago for Collin County Humane Society and love it!! There are no words to express the joy of an animal finding their Furever home! My work experience consists of over 25 years in the Administrative Assistant / Receptionist field.

Working at Vetsavers Pet Hospital is truly a wonderful opportunity, which gives me the chance to be with great people and adorable animals of all sizes.

I look forward to welcoming you to Vetsavers and helping make your experience here as great as possible.
