From the moment I arrived I was treated with courtesy and respect. Dr Sandoval had a warm and friendly manner and was knowledgeable about and sensitive to my concerns. He explained everything to me in a way that I could clearly understand and I was comfortable about what to expect during my upcoming procedure. I would gladly refer his services to others. 👍🏽👍🏽
