Meet our friendly staff at Happy Valley Veterinary Hospital


We would like to announce the promotion of Dr. Sara Caldwell as the Chief Medical Officer of the Pacific Northwest through Wellhaven PetHealth! As of November 1st, we have moved from being privately owned by Dr. Caldwell to becoming a part of the Wellhaven PetHealth family. This change in ownership has opened up more opportunities and allowed us to provide greater medicine to our clients. This will not change the day to day activities and we will still be operating as usual. However, due to the change in Dr. Caldwell's title, this does mean she will not be practicing internally anymore. We are all sad for this loss but we're so happy for her to be moving into the next stage in her career! If you have any concerns or questions, please don't hesitate to reach out. We also welcome you to come in and meet any of our other three doctors! Give us a call or walk in at any time!
