Tiffani Witten, MS, DVM, CCRT, CVA
Owner & Medical Director

I have always had a passion for animals, and upon discovering my passion for medicine as well, I embarked on this incredible journey of a veterinary career. I’m a native Texan and I attended Texas A&M University and graduated with an undergraduate degree in Biomedical Science, a Masters Degree in Nutrition and Doctorate of Veterinary Medicine in 2003.  We moved to St Louis and I have been practicing veterinary medicine since then.  I am also certified in rehabilitation and small animal acupuncture  originating from a desire to better serve my patients that needed additional care in terms of pain, increased quality of life, and having more tools at my disposal to offer clients and pets in need!
 I am married to another Aggie, Ty, who is co-owner and supportive of our family in so many ways!  We have two children, Taylor and Teagyn, who are the light of our lives.  I also have one Golden retriever, one papillon and one French bulldog.  They always keep life interesting and fun!
My other special interests include nutrition, exercise physiology, pain management, and animal behavior.  In fact, I believe that exercise, good nutrition and understanding your pet’s behavior are the key ingredients for a healthy and happy pet!  
My favorite aspects of this career are the relationships built with clients and working with them to provide a happy and healthy lifetime for their pets and families!
When I’m not at work, I like to spend time with my husband, children and pets.  I love to go running or hiking with my dogs and family and do anything active and outdoors.   I have a weakness for Mexican food and also enjoy cooking and trying new recipes.

Dr. Jessica Borgmeyer

I have always loved animals and never had a doubt I wanted to be a veterinarian. The first word I spoke was “cat” and some of my first memories are playing doctor with our dogs.

I graduated from the School of Veterinary Medicine at the University of Missouri in Columbia after earning my bachelors degree in Biology from Truman State University with a minor in Equine Science. After graduating from vet school I moved back to St. Louis to begin in private practice with an emphasis on urgent care.

My family consists of my husband and our two beautiful children. Our fur family at home includes two dogs, a shepherd mix and poodle mix, and a cat. Outside my family and veterinary medicine my other passion is in dressage. I have been competing for 15+ years. The partnership that develops between horse and rider is so beautiful.  My other interests include cooking, trying new restaurants, traveling, crafting, and exploring with my kids.

My interests in veterinary medicine are critical care, internal medicine, and helping develop the human animal bond. I love having pets as part of my family and helping pets be healthy members of other people’s families as well. I look forward to helping your loved one throughout their life.

I have had a strong love of animals and science for as long as I can remember.  Veterinary medicine was the perfect career to pursue both of my passions.  
I received my undergraduate degree in Biology from Truman State University, during which time I worked at a kennel, mucked horse stalls and took care of geckos in the Herpetology lab.  I decided to follow my interests in animal behavior and completed a master’s degree in Biology with an emphasis in animal behavior from the University of Missouri-St. Louis.  During that time I worked as a veterinary technician, and gained not only technical skills, but also a profound respect for technical staff and all that they do.  I then went on to pursue my degree in Veterinary Medicine at the University of Missouri.  Go Tigers!  After graduation I worked at an emergency clinic for a year before moving to general practice.  What I love about general practice is following a pet from puppy or kitten hood through their senior years.  
I have a passion for animal welfare and medicine.  I try to make every pet’s visit to the veterinarian as enjoyable as it can be.   I also understand that veterinary medicine is an ever-changing field, and I strive to stay on the cutting edge.  I am a member of the Missouri Academy of Veterinary Practice, an organization for veterinarians who complete additional continuing education hours.
When not working, I like to spend time with my husband and two beautiful children.  I also love to run with my dog, Boo.  She is a Coonhound mix, and the best running buddy I could ask for.  Our family is completed by two spunky and mischievous cats, Jon Snow and Samwell Tarley.
