Meet Our Team

Dr. Justin Toth is the founder and co-owner of Dallas Highway Animal Hospital, an independently owned veterinary practice serving the West Cobb community since 2001. A 1997 graduate of the Auburn University College of Veterinary Medicine, Dr. Toth founded Dallas Highway Animal Hospital with a commitment to providing high-quality, personalized veterinary care while building a practice that feels connected to the community it serves.

Today, Dr. Toth co-owns Dallas Highway Animal Hospital with his longtime associate, Dr. Roberts, who is gradually transitioning into ownership. Their shared goal is to ensure the hospital remains family-owned and independent for years to come--preserving the personal relationships, local decision-making, and commitment to the community that have defined the practice since its founding.

Dr. Toth has been an active leader in veterinary medicine throughout his career. He currently serves as Treasurer of the Georgia Veterinary Medical Association and is a Board Member of the Independent Veterinary Practitioners of America. He also serves on Auburn University's Veterinary Advisory Board, The Farmer's Dog Advisory Board, and the Cobb County Animal Services Board.

For more than a decade, Dr. Toth served as President of the Cobb County Veterinary Medical Association, one of Georgia's remaining active local veterinary associations. In January 2027, he will transition to the role of Immediate Past President. His involvement in organized veterinary medicine reflects his belief that veterinarians are stronger when they work together as colleagues, support one another, and remain actively engaged in their profession and communities.

Dr. Toth has called West Cobb home since 1998. For him, Dallas Highway Animal Hospital is more than a veterinary practice--it is part of the community where he has lived, raised his family, built his career, and established lifelong relationships. More than 25 years after opening the hospital, he remains committed to keeping veterinary medicine personal, independent, and locally rooted.

Dr. Laura Roberts has been at Dallas Highway Animal Hospital since 2018 and is now in the exciting role of co-owner. A Georgia native, she earned her undergraduate degree from Georgia Tech and her Doctor of Veterinary Medicine from the University of Georgia. Passionate about animal health from an early age, Dr. Roberts is dedicated to providing compassionate, thorough, and efficient care to every patient and their family.

When she's not in the clinic, Dr. Roberts enjoys spending time with her husband, young daughter, two dogs, and three cats. She also loves reading, baking, bird watching, and hiking.

Dr. Tietjen came to Dallas Highway Animal Hospital in November of 2022 and has enjoyed becoming a part of this family.  He was born into a military family and moved around every few years until his parents settled on the family farmstead in central Illinois.  He received his DVM from the University of Illinois in 2003.  Dr. Tietjen enjoys learning new and improved ways of taking care of people’s babies.  He chose this field because it allows him the opportunity to make a difference that families will hopefully appreciate and enjoy.  He enjoys watching/going to Brave’s games along with his two daughter’s activities/events.  His goal is to listen to clients’ concerns and discuss the options with clients and make the best decision based on the situation.

Dr. Haber has been part of the team since 2022 but has been practicing for over 20 years.  She loves the human animal bond and strives to strengthen it every day.  Originally from New Jersey, she earned her DVM from the University of Illinois, graduating with highest honors.  Dr. Haber has a special interest in internal medicine and preventive care.  Dr. Haber has always known she wanted to work with animals, and she finds it incredibly rewarding to be able to ease their pain and support the families who love them.  Outside of the clinic, Dr. Haber is very busy with her two daughters and all their activities. Her goal is to make every visit a positive experience for both pets and their people.  She believes in kindness, communication, and a little humor when it’s needed the most.

Theresa is the Hospital Administrator at Dallas Highway Animal Hospital. Since joining the team in 2013, she has brought dedication, skill, and a genuine love for veterinary medicine. While working full-time, she completed the Veterinary Technician program through Penn Foster College, earning her Associate of Science Degree. She then passed the Veterinary Technician National Exam and became a Licensed Veterinary Technician.

Theresa is deeply passionate about staying current with advancements in veterinary care and believes that pets are family—treating each one with the same compassion she gives her own. Originally from Montana, she enjoys traveling there and to Rhode Island to visit family. Outside of work, Theresa can often be found relaxing with her three cats—Louie, Frankie, and Charlie—or spending quality time with her brother’s dogs, Hondo and Scout. There’s never a dull moment with her furry companions!

Jen is a licensed veterinary technician.  She joined the practice in 2014, though she has been in the veterinary field for almost three decades.  Her goal is to help strengthen the human-pet bond.  Originally from St. Louis, Missouri, Jen moved to Georgia as a kid.  She attended middle and high school in Conyers, and went to Georgia Tech.  While originally studying chemical engineering, she left school to follow her true passion of animal care.   When not at work, you can usually find her at the movies, hosting a weekly game night or just relaxing with her two dogs, Odin and Frodo.  It is Jen's goal to give your pet the best care that she can, and to help you understand what we can do to help them!

Jessie is a Certified Veterinary Assistant III with a passion for caring for the scared, defensive, and often misunderstood pets that need it most. Since relocating from California to Georgia in 2005, Jessie has dedicated her career to advocating for animals that others might shy away from—earning their trust and giving them the care and respect they deserve. With a calm presence and a big heart, she brings compassion and skill to every patient interaction.  When she's not at the clinic, she loves getting lost in a good book, diving into Disney magic, and cheering for the Braves!

Chris is a Certified Veterinary Assistant I at DHAH. He joined the team in December of 2022, and has been in the field since he was a senior in high school. Chris was born and raised in Kennesaw, Georgia. He has always had a deep passion for animals his entire life and could always be found outside looking for any animal he could catch. In his free time, he enjoys hiking, cooking, and exploring the mountains of North Georgia. Chris has a 2-year-old Border Collie named Daisy at home who is totally crazy in all the good ways. When it comes to helping patients in the clinic, he makes sure that he treats every pet like they were his own and strives to make them as comfortable as possible.

Born in Montana and raised in Nevada, Mackenzie has always had a deep connection with animals and knew from a young age that the veterinary field was where she belonged.  Mackenzie joined the team at DHAH in 2022 as a veterinary assistant.  She brings compassion and energy with a true love for what she does and making sure every furry patient feels safe and cared for.  Outside the clinic, you’ll find Mackenzie ed up with her two rescue pups, spending quality time with her niece and two nephews, cheering on the Volunteers or the Braves.  With a big heart and an even bigger personality, she’s all about bringing positivity and dedication to every part of her work.

Danyell was born and raised in Kennesaw, Ga.  She has been passionate about animals for as long as she can remember.  She started her career in veterinary medicine at 17 years old working in a kennel and has continued learning and growing in the field ever since. Her main goal is to make veterinary visits as stress-free as possible for all patients - even if that means lots of treats!  Danyell has two black cats, Nismo and Zenki, as well as three rescue mixed breed dogs, Annie, Caremella and Senna.  When not at work, she enjoys spending time with her husband, sewing/crafting and adventuring with friends.

Mercy is proudly both a cat person AND a dog person!  She has been working in veterinary medicine since 2014 and is deeply committed to fear-free care, speaking up for her patients, and preserving the personal, compassionate side of veterinary medicine. Mercy's dedication to animals knows no bounds.  She would quite literally jump in front of a moving vehicle to save your pet - or even a stray! (Honestly, she'd probably rather do that than talk on the phone.)

After more than a decade of fostering animals and helping them find their forever homes, Mercy has finally settled into life with a small menagerie of her own: six dogs, four cats, and her partner.  They all share a cozy home amid the trees.

Zack has been working in the veterinary field for over 20 years, and his passion for helping animals has only grown over the years.  He truly loves what he does and couldn't imagine himself doing anything else. Zack has three dogs, three cats and a snake, so its safe to say animals are a big part of his life both at work and at home. When not at work, he enjoys hiking, working out and spending time with his family.

Noah has been part of the team since May of 2024 and loves establishing new clients and further assisting current clients with their fur babies’ needs.  He grew up in Lonoke, AR, and is currently attending UMASS Global in the pursuit of obtaining a degree in Psychology.  Even though his goal in life is to become a counselor, he has always had a passion for working with animals.  He strives to provide the best customer service possible and is rewarded knowing that we provide the best care possible here at DHAH.  Outside of the clinic, Noah enjoys reading, catching up on movies/shows, listening to music, and spending time with his 3 cats Lynx, Jynx, and Lark.  His goal is to make every visit as stress-free as possible and always approach every situation with a positive attitude.  If he is working in the lobby, you will be serenaded with Taylor Swift all day!!! (He’s her biggest fan) 

Hannah has been working in veterinary medicine since 2017 and is passionate about helping pets feel safe, comfortable and cared for.  She has a special interest in feline medicine and fear-free handling, and loves finding ways to make veterinary visits as low-stress as possible for both pets and their owners.  When she's not at work, Hannah's life is still very much centered around animals! She shares her home with eight cats, a crested gecko and a bearded dragon.  Animal well-being is important to her both inside and outside the clinic, and she loves advocating for the health and happiness of every animal she meets.

Outside of work, you can usually find her playing soccer, going to the gym, hunting for treasures while thrifting or enjoying a well earned nap!

Amber has been a valued member of the DHAH team since 2016. As a veterinary receptionist, she brings a warm, knowledgeable presence to the front desk and takes pride in helping clients care for their pets. She especially enjoys educating pet owners about the importance of heartworm, flea, and tick prevention for both dogs and cats.  A Dallas, GA native, Amber is passionate about supporting pets and their families in living their happiest, healthiest lives.

She takes pride in being a friendly face at the front desk and enjoys building relationships with clients and their beloved pets.

Jenay Marie joined the DHAH family in December 2025.  She grew up in an Air Force family and that life brought her up north to Alaska where, in 2020, she began working in veterinary medicine right out of high school as a kennel attendant. It didn't take long for her to discover her passion for the medical side of veterinary care, and she quickly began cross-training as a veterinary assistant and receptionist.  She puts her growing knowledge and experience to work wherever she is needed, whether it is holding a wiggly patient in the back or greeting clients and getting know patients at the front desk, she is always happy to lend a hand.  JJ, as we like to call her, has two pups of her own: Buddy, a Great Dane and Wynter, a miniature schnauzer.  Talk about a different in size!

When she's not at work, JJ enjoys nature photography, writing, spending time with family and friends and all things crafty and Halloween-related.  

Thanks to Dr. Toth, I joined the hospital staff in April 2009. I enjoy being around other cats, dogs, and people. I am always excited in the mornings to get my special breakfast and treats, but 4 pm is the best part of my day because that is Churu time! Most of time you can find me lounging in my cat tree bed, office chairs or on the desks of my favorite people. I do get the zoomies from time to time just to let everyone know I am feeling good and happy!

I joined the hospital staff in 2024. I was a little shy and quiet at first, but I have adjusted well, and I love all the attention I get daily. I enjoy being brushed and pet frequently. I have some nice beds where I spend most of my time taking cat naps. When I am in play mode, I have a favorite bird toy that I toss around and play with.
