This was my first visit to Dr Klimas, although I've had CFS for 19 years. I was generally impressed. If you go, here's what to expect: The office is currently not very organized. I was told to mail my new patient paperwork to them, but they couldn't find it for awhile and I had to fill it out again. We got there quite early so this was OK. Mail your paperwork if that's what they request, but make a copy and bring it with you. My 2 hour appointment included 4 hours of waiting. Bring lots to read! The waiting room is quite small. The walk from the front door to the office is very short (like 20 steps). Likewise the walk from the office to a limited lunch source (empinadas, chips and drinks) is very short. The questions asked by the doctors are excellent and you will feel very much like you're with people who understand and sympathize with your illness. I was given 2 prescriptions and thorough explanations about what they are for. I had a physical exam and blood drawn but no physical tests such as tilt table or stress test. Come prepared to take notes or bring a significant other/friend to help with this. It's a lot of information, and my taking notes prevented my leaving with the wrong prescription. Dr. Klimas is very friendly and upbeat. Her assistant is very nice also. My followup appointment will be in 6 weeks by telephone, as I live far away.
