We Vet Better!

No corporate nonsense. Just honest, locally owned, and community-driven care.

Our accessible care model gives pet owners options—bringing back honest, trustworthy, and genuine care."

Locally & Privately Owned.  I’ve seen how the corporatization of veterinary practices—and even some privately owned clinics driven more by profit than purpose—have made everyday care harder for staff and increasingly unaffordable for pet owners. At Horizon, we’re returning to what matters: excellence, integrity, and selfless service, delivered by a team that believes in doing the right thing.

We call it Accessible Care, and through our proprietary "Sustainable Veterinary Ownership" model, we reject outdated corporate systems and using cost-cutting & price-gouging, putting profits ahead of even the basic standard of care. Horizon is the first practice in our area to offer a sustainable solution to rising veterinary costs—without sacrificing quality or undervaluing the skill of veterinary professionals or offering them gimmicks that promise them wealth but don't really "Support" them as advertised. We are not allowing greed to guide our model!  It’s care truly centered on pets and people, not profits, with NO CORPORATE NONSENSE!

Took my Yorkie & Bully for shots and a microchip. Dr. Rainer & Heather were very knowledgeable, personable and accommodating. My furbabies recieved there shots without pain or discomfort. *Bonus was Puffin the sweetest Clinic cat.

The entire staff is very welcoming and professional. It is rare to find a veterinarian who balances high-level expertise with such genuine kindness, but Dr. Rainer does exactly that. I feel completely confident in putting my trust in him to treat my crew.

Best vet ever!!! Our dog is very nervous and timid during vet visits, and at our first appointment Dr. Rainer suggested we do the exam in their fenced in dog park!! We loved that they accommodated to our Lola girl and made her more comfortable during the process! They really listened to our concerns and gave us a treatment plan that worked exceptionally. It was so nice to finally have an answer for our girl and get it treated rather than just be told “oh it’s just allergies”.
google
I wish we had found this team much sooner! The staff always treats us as VIPs and they love our boy Milo. Thank you so much for taking such good care of our dog!
google
Our West Highland Terrier needed an urgent visit this morning and our regular Veterinary Clinic could not see him. Dr. Rainer at Horizon was able to get him in within an hour!!! Fantastic Team!!! They have Fergus on the road to recovery ASAP!!! Can’t say enough great things about Horizon, theiy are great!!!

I had to make an emergency appointment for my older bunny who had stopped eating and wasn't responding to critical care. I was nervous about going here because this isn't my normal vet, but Horizon Veterinary and their staff are amazing. Everyone that I talked to was very polite, enthusiastic about helping, and willing to explain things to me.

They handled my bunny very gently and spent lots of time in the exam room talking to me about the plan for the visit. When they had to take bunny back for X-rays, I could hear the staff speaking very affectionately and baby-talking to him.

Everybody that works here clearly cares about animals and will treat your pet like one of their own. If you have a rabbit, I would highly recommend this place.

I will SCREAM from the rooftops, TAKE YOUR FUR BABY HERE. You won’t regret it, I promise you.
If I could give them more than 5 stars, I would.
My dog loki is my soul dog and my whole world. Not only did dr.rainer take the time to talk to me on the phone for 30 minutes before even seeing loki to calm me down while I was panicking over him going under for an exploratory again.
He also took loki right in the moment my husband got him to the vet and updated us every minute along the way. He even called us MID SURGERY to update us with unfortunate findings and was extremely honest in what he was comfortable doing. He has connections all around the vet world and meet him for 1 minute and you’ll understand why he’s so respected.
He knew the ultrasound tech that took our dogs ultrasound at our primary vet (though we plan to switch to horizon with our 3 dogs after this without a doubt) and called her to walk through all the findings with her.
***If your fur baby has a medical emergency, this is THEE place to go.***
Just call first and he will be VERY honest if he can handle it. The staff her is also nothing short of amazing. You can see their love for animals and how much they just want to help YOU be okay as well.
I am VERY particular with who handles my fur babies and this vet I would and have trusted them with my fur babies lives and honestly at this point they’re the only vet office that helped my sanity during all of this.
Oh AND pricing is well beyond reasonable. For the surgery and check up and everything in between, it was 1/8 of the cost of an animal hospital.
Their 3 mottos they have, you can tell that they live, eat and breathe - kindness, authenticity, and transparency and oh man, do they exceed this.

Saved my dogs life! Advocated for my dog when the emergency vet wanted to put her down for something she didn’t have. The whole staff is wonderful.
