15th Street Veterinary Group

We are a walk-in clinic, so scheduling appointments is only necessary for surgical procedures, bathing, and boarding. This allows us the flexibility to tailor each visit to the patient's needs without worrying about going over an allotted amount of time. It does, however, mean that there could be a wait time depending on what is happening that day. We take emergencies during regular business hours, but refer to the Animal Emergency Center overnight and on weekends.

Our doors first opened at our current location in 1965 as Hohmann Veterinary Hospital, under the ownership of Dr. Donald Hohmann. Dr. Ed Wagner joined the practice as an associate in 1980, but later became a partner. A third veterinarian was added to the practice in 1987 when Dr. Mark Shackelford joined the group. We officially became 15th Street Veterinary Group in 1990 when Dr. Wagner and Dr. Shackelford became co-owners of the clinic. Dr. Hohmann remained on and continued to practice until his death in 1995. Dr. Erin Reed joined us in 1999 and became a co-owner with Dr. Shackelford, Dr. Wagner having sold his half of the partnership to her in 2015. Dr. Wagner continues to work as an associate veterinarian and Dr. Kara Herrington joined us in 2014.

  • David White, RVT

    Registered Veterinary Technician

    I have lived in Tulsa for most of my life. I grew up in the shadow of the DX refinery, then spent 4 years in the Air Force. I returned to Oklahoma and worked in wholesale or retail sales for over a decade. In 1994, I lived on a horse ranch in South Tulsa caring for boarders and a small barrel racing arena. I loved being surrounded by animals, so I applied at a small Veterinary Clinic where I began learning from the ground up. After a dozen years of boarding facilities, hospitals, the Tulsa Zoo, and some area shelters, I decided that I wanted a formal education to coincide with my life experiences. I attended the TCC Vet Tech Program while working full time and received an Associates Degree in Veterinary Sciences. Then, in the spring of 2004, I sat for and passed the National & Oklahoma State Boards to become a Registered Veterinary Technician. I came on board 15th Street Veterinary Group in October of 2007. I have one son, Ryan, and a granddaughter, Kinzley, who currently live in OKC.

I love to read, cook, travel, and go to the movies. I graduated from TCC's veterinary technician program in 2010. This career is the best I could have chosen. I love spending my day around animals and I couldn't think of a better clinic to work for.

  • Katie Glavas, RVT

    Registered Veterinary Technician

    I was born and raised in Tulsa, OK and have always lived here. The only time I lived outside of Tulsa was when I attended the University of Oklahoma in Norman. My focus was human medicine at first, but one summer between semesters I began volunteering at an animal hospital. I've always had a soft spot for animals, but that's when I realized my passion for veterinary medicine! I changed majors and enrolled at TCC in their vet tech program in 2012. I graduated in May 2014, took my state and national exams, and received my Registered Veterinary Technician license. I worked here at 15th Street for my externship and once that was over I was hired as a kennel assistant.  After I got my license, I was hired as an RVT and I work some reception. You'll see me all over the clinic! I love all the clients, their pets, and the people I work with. I couldn't be happier working at 15th Street Veterinary Group. I'm so glad I found my calling and the best place to work!

    Reception

    A few words from Carolyn, aka "the lady at the front desk with gray hair." I started at this clinic in September 1968 when it was Hohmann Veterinary Hospital (yes that was before most current employees were born!). I continued on with Dr. Wagner and Dr. Shackelford when it became 15th Street Veterinary Group. I have welcomed a lot of clients to this clinic over the past 44 years.

    Reception

    I was born and raised in a small town in Arkansas. I just recently moved to Tulsa in October (2016). I have a 6 year old German Shepherd named Bosco and I take him with me anywhere he is allowed to go. 15th Street Veterinary Group was the first place I started working when I moved to Oklahoma and the staff welcomed me with open arms. I could not imagine working anywhere else.

                  
  • Marina Keating

    Reception

    I became a part of this wonderful clinic family in September of 2014 when I applied on a whim, hopeful to finally fulfill my passion for animals. I was hired a few days later and I haven’t looked back since nor did I know that it was possible to love a job so much! I have three amazing fur-babies of my own; Marley – my spoiled rotten American Pitbull, Chedda Cheez – my fat little kitty cat, and my newest addition Bernie – the Morkie. When I’m not working and helping with your pets, it’s a safe bet that I am either training Aerial Silks with my friends, binge watching Netflix, or napping with my animals. I am also a notorious “cookie monster” and I love music, festivals, camping, and traveling with my fiancé.
