I have been quite pleased with my experiences with Dr. Stroberg at Church Ranch Veterinary Wellness Center.
When I have brought either of my two dogs in with a problem, the vet has performed diagnostic tests and then based treatment on the results. He has been aware of what tests give reliable results and what tests give too many false positives/false negatives and has saved me the expense of the tests that are on the market, yet don't give reliable results.
I personally like his scientific approach. It is the way human medicine is also practiced these days. When I go in, my doctor doesn't just look at me, say maybe it's xx, do yy--he runs tests first. I have been to other vets who don't use diagnostics or have referred me to specialists if I wanted them ($$$$). I am not comfortable with vets who just guess--they say try these antibiotics and come back if it doesn't get better. So I have found it refreshing that Dr. Stroberg uses diagnostic tests to make his diagnoses. Yes, they cost money, but I think his prices are quite fair.
I am usually able to get an appointment on the same day I call if I wish, and there has never been an "emergency charge" on my bill.
The only negatives I have experienced are:
The exam rooms have not been clean when I have been there. There is always a fair amount of fur on the ground. Other vet offices I have patronized routinely sweep the floor and wipe down the exam table with alcohol after each use.
The doctor's bedside manner is kind of cold and businesslike. He lacks warmth with both people and dogs, in my opinion. I can deal with that since I believe the care my dogs are getting is the best I have found in the area, but he could try a little harder on the interpersonal side of things.
