I am in Canada, but just did a Google search which brought up two possibilities - The first one has some positive reviews on Yelp for treatment of Dogs.
I am in the Los Angeles area and located my holistic veterinarian using this website: http://www.ahvma.org/. I found a few that were within an acceptable driving distance, I reviewed their websites, I read online reviews.
Once I made my choice, I dug a bit deeper online. I also made inquiries about this particular office at the locally-owned pet supply store where I purchase food. Finally, I found out that my boss's wife used to work there and both spoke highly of the veterinarians and staff.
