“Laci Dykstra is the best. She is on top of things. Her nurse Leanne is top-notch also.”


“Even though the Red Rock Clinic is extremely busy, they still take the time to explain things and answer all of my questions.”

“My Granny was in the hospital for two days with several things going on, but the major issue is/was blood on the brain. Dr. Errthum took care of my Granny with kid gloves. She was very educational, kind, and thorough with everything that she went through (is going through) and what we can look at doing in the future. I wanted to say a big ‘Thank You’ to Dr. Errthum and her staff!”
