I've had dogs all my life and seen various vets...and i must say Dr. Wengren is the best.  He is prompt, calls back soon, and has excellent bedside manners.  He is very kind with the animals and their owners.  I always feel like i am getting the best care.  And one other thing....i really like that he does not over medicate or have to take un-necessary actions that i believe others are quick to prescribe.

Dr. Wengren is expert, very reasonably-priced, and above all kind and incredibly gentle with my senior cat. We went to him many years ago when we were in the area, and I was so happy to see that he's practicing in Portola Valley. Very highly recommended. Read Less

Soon after moving to the Peninsula from Humboldt County, we planned a scuba trip to Utila, Honduras, and had to figure out where to board our dogs. They needed vaccinations, and were also due for their annual physical. My landlord recommended Dr. Wengren in Portola Valley, and I am so glad we took his advice. He's got a great demeanor (my dogs give him kisses), very professional, and the little office in Portola Valley totally reminded me of the rural north, including the resident chicken out front. Labs love that. But most of all, he's competent. My brown dog...Barley...is 11 now, and we joke that he's a bump with a dog attached. He's got those fatty bumps everywhere that dogs seem to get as they get older, and when he first started getting them, we had them tested to make sure they weren't anything to be concerned about. My black dog...Morel...is 10, and had one bump on her back. It felt different, harder, but my old vet in Garberville dismissed it, over a year ago, saying, "oh, let's just keep an eye on it and see if it gets bigger."Dr. Wengren took one look at it, and said yeah, it should be tested, and it turned out to be a mast cell tumor. Those are incredibly common apparently in older dogs, and are no big deal if you catch them early enough. You can imagine my guilt, and subsequent ill wishes on my prior vet up north. Morel had it removed 2 weeks ago, and will get her staples out this week -- she did great, healed fast, and he got it all out. Though it was a stage 2, he removed enough around the tumor that the margins were clean.So yeah, Dr. Wengren rules. If Portola Valley is too far, he's also got a RWC location. (Moral of the story? If you love your dog, and he's got a bump, get it looked at. It only costs about $30 to get it poked with a needle and tested -- way worth it.)---Again, big fan of Dr. Wengren. My brown dog seemed to have sprained his front leg trying to get up onto the sofa, and my husband took him to see Dr. Wengren the next day. Rather than just shrug it off, he did an x-ray just in case, unfortunately finding a bone tumor. He referred us to Veterinary Medical Specialists in San Mateo (will review them later), and Barley became a tripawd just before Thanksgiving -- he's recovering so well, and I couldn't be prouder of him. What a champ. Anyway, just glad to have such a competent, caring primary vet -- we really trust him. Read Less
