Courtney K.

with Gretta May

Dr. Fagen is professional, compassionate, and extremely knowledgable.  Taking my dog to Dr. Fagen was truly the best decision I have ever made.  Dr. Fagen helped my dog and I get through separation anxiety when nobody else could and I am extremely grateful.  Working with her was a delight and her recommendations were easy to implement.  I'm a professional dog trainer and even we need help sometimes.


with Fernando

Dr. Fagen helped us to course correct when our beloved sixteen-year-old Persian began acting out two years ago.  He was defecating out of his litterbox, and the situation was creating a great deal of stress for us both.  She was able to examine him and physical causes for his stress symptoms. Also, she offered us coaching on how to more efficiently and kindly treat the behavior.  I would highly recommend her to any person ready to have a healthier and happier feline at home.

We are so grateful to Dr. Fagen for her help with prepping our dogs for the arrival of our baby! We have been so worried about how our dogs would react to the change, and Dr. Fagen was extremely thorough, giving us all the tools to be able to feel safe and secure in preparing for this big moment in our lives.
