I am so grateful to Dr Mark Horowitz! I was referred to him because I was under another Dr's care ,unfortunatley I was not under the right treatment. He immediatley took test's changed my medication that was not right , that was causing other medical issues, blood disorder, kidney issues, high blood pressure. I can only say that due to him and his expertise and care I am finally on the right path. He is so worth the the trip it takes us two hours from where I live . When you are dealing with seroius issues like I was you make the trip ! And I just want to thank him for everything hes done for me. And his amazing staff that has alway's gone above and beyond to help me feel comfortable and safe in their care.
