Dr. Simon and her team were incredibly kind, attentive, and compassionate while caring for my mom. One thing that stood out to me was how they had a nurse available to help translate from English to Spanish whenever needed, which made such a difference in helping my mom feel comfortable and understood.
It really takes a village, and Dr. Simon’s team cares about their patients and families. My mom and I are so grateful for the level of care, patience, and professionalism they showed throughout the entire experience. Thank you, Dr. Simon and Team!
