Here are some testimonials and google reviews.
This horse had colic surgery 12 hours prior and is feeling great. Colic surgery is expensive and stressful but it is the only option for horses with certain conditions. Those conditions must be diagnosed quickly and surgery must be done in a timely way for the best possible results.
