    I had a great experience over all.
    Dr. Cortez was my original OBGYN during this pregnancy and absolutely loved her. Dr. Buchanan took over my medical care since her leave and had been exceptional. He has a kind demeanor and is helpful with questions you may have.
    I was very comfortable with Dr Buchanan and his staffthought his office to be very clean and efficient Dr Buchanan answered all my questions and did a good exam.
    Great Doctor and office personnel!!
    I really liked Dr. Buchanan. He took the time to explain what my test results meant and what the next steps were.
