Arrived after hours at 9pm and was seen immediately for an acute back injury. The staff were so welcoming and kind. Communication with the nurses and doctor was smooth - they understood my issue easily and I felt were all judgement-free (the nurse was even making jokes with us to lighten the mood). I received IV and oral medications for my pain. These, plus the consultation, were at a very low price. I recommend this clinic for tourists who need immediate medical care!

The ladies working here are absolutely wonderful! They are so attentive and care deeply about the people in their care. They communicate clearly about prices, and are very professional overall. I’ve been to several clinics across koh tao and this is the best one by far.

My friends had a serious scooter accident... A classic Thai occurrence, but no less stressful and traumatic. Locals called emergency services for us, and we didn't know what to expect. The ambulance crew was amazing 👍 Calm, attentive, and incredibly kind. Fantastic service, I highly recommend them! Special thanks to Ammy and her sister Ging, who work together and took excellent care of my friends! Thank you so much 🙏

A very friendly and competent team! The doctor and staff were truly wonderful and caring. They explained everything very thoroughly and gave me everything I needed for aftercare, even adding computer-printed stickers with the dosage instructions to the packaging! They recommended a follow-up appointment in a few days, which I will definitely attend. I already feel much better after just a few hours! Card or cash payments are accepted. I can recommend this clinic to everyone!!! Simply fantastic!!!

I injured my leg badly. My insurance company referred me to this clinic. The staff was very friendly and welcoming, everything was easy, relaxed, and efficient. They saw me, examined me, took X-rays, treated me, and gave me a full kit for further treatment. They immediately sent me a photo of the X-ray and the examination report via WhatsApp. I didn't have to pay any extra. A huge thank you to the doctor and staff! It's unpleasant to get injured on vacation, but it's great that you can always count on high-quality care!
