I have used them three times for laser vein occlusion therapy and all three were successful. But just completed the third and went back for the included schlaratherapy to clean up some spider veins in my ankle. Two days later I have a staph infection in that ankle. The doctor prescribed an antibiotic and sent me on my way . Three days later and I am barely better and no call to check from the doctor who caused it. Looking back the staff at the clinic are not registered nurses. I would never use them again.
