One week could never be enough to thank our incredible veterinary technicians for their skill, patience, and boundless compassion. From the long shifts and quiet moments of comfort to the endless care behind the scenes, our practice simply could not run without them. 🐾❤️‍🩹
A massive, heartfelt thank you to our superstar team: Natalie, Reesha, Christine, Fallon, Cuda, Sabrina, Jess V., Vanessa, and Achtli! 🩺💖
You all are the heart of our clinic and the heroes of every wagging tail and purring patient. We appreciate you today and every single day! ✨️❤️

As National Vet Tech Week continues, we are thrilled to spotlight the Vibrant Vanessa! 🌟
Vanessa is fresh off a major milestone, having graduated from the Joliet Junior College (JJC) Veterinary Medical Technology program this year! She is already putting her skills to work on our floor while dedicating her free time to studying hard for her upcoming VTNE boards. We have no doubt she is going to crush it! 🎓📖🤘🏻
When it comes to patients, Vanessa has a huge soft spot for the little ones—and she admits she might be just a tiny bit biased toward her absolute favorite breed, the Shih Tzu! 🐶❤️
When she steps away from the clinic and her study guides, Vanessa loves nothing more than curling up and getting lost in a great romance novel. 📚✨
Vanessa, your energy, dedication, and passion for learning make you such a valuable asset to our team. We are so proud to support you as you prep for your boards! Please join us in wishing Vanessa a happy Vet Tech Week and wishing her luck on her VTNE! 👇🎉

For National Vet Tech Week, we are so incredibly proud to celebrate the Journeyed Jess V.! 🌟
Jess’s story with Companion is the ultimate journey of dedication. She first walked through our doors 4 years ago as an extern. We knew immediately she belonged on our team, hired her on, and have watched her grow into an amazing leader on the clinic floor. 📈💪
This year marked her biggest milestone yet—Jess officially graduated from tech school, conquered the VTNE, and officially became a Certified Veterinary Technician (CVT)! 🎓🎉
In the hospital, Jess shines brightest in the surgical suite. Her absolute favorite part of the job is managing anesthesia, where her sharp focus keeps our patients perfectly safe and stable. 🩺⏱️
When she steps out of her scrubs, Jess loves to unwind by getting lost in a good book or heading outdoors for long walks with her beautiful huskies, Sabrina & Sol. 📚🐺🐾
Jess, watching your 4-year journey from an eager student to an expert CVT has been an absolute privilege. Thank you for your unwavering commitment to our patients and team! Drop a comment to congratulate Jess on her amazing year! 👇❤️
