Dear Trinity County Community, 

UPDATE as of Monday March 29th:

Our building is re-opening! In accordance with CDC Guidelines, we will require all employee personnel and clients to wear masks while indoors. We will continue to practice social distancing and constant cleaning protocols. Number of persons in the lobby and exam rooms will be limited so please only bring a maximum of one person per pet to your pets’ visit. Exam rooms are limited to one family member at a time. If numbers are exceeded, we may ask you to remain outside until rooms are available. Additionally, please allow our team members to hold and snuggle your pets during their examinations. If you are more comfortable with a curbside visit, we are happy to accommodate, just call our office upon your arrival, 530-623-5757. We can’t wait to see you all again!

EFFECTIVE 11/10/20: Due to recent COVID-19 outbreak in Trinity County, our Lobby is currently closed to the public to maintain social distancing guidelines. If you have a cell phone please call us from your vehicle to let us know that you are here. If you do not have a cell phone please knock on the front door or ring the doorbell to the right of the entrance. Please wait in your vehicle and have your phone available as the doctor or technician may need to speak with you during the examination.
We can take a credit card payment over the phone or retrieve other payment type before returning your pet to you. We are minimizing all direct interactions as much as possible. Thank you for your understanding in these matters.
We are doing our very best to keep up with the needs of our community. Currently we are scheduled about 3 weeks out for preventative care appointments and 4 weeks for surgical and dental procedures. During this time we are prioritizing patients and managing pets that need to be seen more urgently to ensure as many pets are cared for. We are actively recruiting for a 3rd Veterinarian who shares our vision and passion for patient care, but will only accept those capable of providing the high level of care we provide our patients. We appreciate your patience during this busy time of year, and want to reassure you that we are doing everything we can to keep all of the pets in Trinity County cared for in a timely manner.
We value all of the patients that you are entrusting us with their care and value you as their pet owner. We kindly ask that pet parents be kind to our team as they are working very hard to meet patient care needs, maintain everyone's safety and attend client requests. Thank you for supporting us!


As COVID -19 impacts everyday life and spreads within our communities, we are dedicated to providing you with the same great service and care that you have come to expect from our practice. At the same time, we are taking great measures to keep our clients, patients, and team members healthy and safe.    

We are working to prevent the spread of COVID -19 by:

  • Limiting the number of clients in our lobby at one time. We may ask you to wait outside or in your car if 6ft of distance between people can not be maintained. 
  • We ask that if you are elderly, or if you would feel more comfortable, please remain in your vehicle, do not enter the building. Call us upon arrival and we can escort your pet to and from the hospital while you wait.
  • If you just need to pick something up, please call. We can accept payments over the phone and deliver your prescriptions or food to you in your vehicle when you arrive. Or utilize our on-line store for home delivery. 
  • Phone consults and photo sharing may be available in certain cases. 
  • We are carefully cleaning all surfaces and all rooms of our practice hourly including door knobs, counter tops, seating, equipment, computers, keyboards, phones, pens, etc. More than usual special care is taken in all public areas and examination rooms to cleanse and disinfect. 
  • Hand sanitizer is available in our lobby for clients and team members to use.
  • We are declining to shake hands with clients during introductions. (We’re being safe, not rude!)
  • We are reinforcing our standard policy of thoroughly washing hands between each patient.
  • And we have stringent protocols on ill employees staying away from the workplace. 

What can you do for your pets and family? 

  • Limit the number of visitors at your veterinary appointments to one person. If someone else rides with you to the practice, kindly ask them to remain in the vehicle.  
  • Make sure that you have enough food, supplies, and medications available for your pets. Please contact us to request any needed refills on medications.
  • If you are experiencing any symptoms or are quarantined and your pet needs veterinary care, we want to help. Please call us to strategize the best course of action. 
  • With school, daycare, and office closures, we may run into scheduling challenges for both our clients and employees. We ask for your patience should these situations cause any scheduling issues.  
  • And remember to: 
    • Wash your hands regularly 
    • Sneeze or cough into your elbow
    • Stay a safe distance from other people whenever possible (6-10 feet)
