I have never seen anyone do an IV as quickly, swiftly, and easily as Mark. My son is severely autistic, 5’5”, and 250lbs. He was not happy to get an IV, but Mark was LIGHTING FAST, and he did it perfectly! We’ve been coming to the hospital for years, and I was so impressed! Also, he was really sweet and patient with my son. The guys he brought in to help hold my son were also really sensitive to his needs. I will happily come back to the ER knowing that Mark will be our nurse.
