Florence Pugh was excellent and reassuring, as usual. Also, I was happy to see she’s training a student Nurse Practitioner. The student also was sharp. My waiting time was much less than my last visit.

I’ve always had good people in the lab but I have to say that the young black woman is the best at drawing blood anywhere I’ve been in my almost 70 years. I don’t look at needles and I had to ask if she had started when she was actually finishing. Need to learn her name. Everyone at the Schertz office is great but I’m so thankful for Flo. Love her! Tara is wonderful and front desk is always friendly and helpful.

My Provider Pryanka Mooney is the best. She is always accurate with providing information and patient when I have questions. Whenever something needs further review, she knows what tests to order. I am thankful for Pryanka’s expertise and love the Schertz location at Hillside
