Recent Patient Comments

"Dr. Gretz is an excellent doctor. He takes time to listen to all concerns. He carefully reviews all data - clinical (labs testing, etc), assessment, and interviewing information with me to make the best decision possible. He is non judgmental and shows care and compassion in his work. He is careful to not "let the ball drop" on any care. He acts when something needs to be addressed. He does not brush off concerns and encourages further testing when needed. I have liked his style so much that I have referred my mother, who is a complicated patient who has chronic conditions, to him. He has been every bit of supportive in her care as well as mine. I have told people about this practice and how easily accessible it is to my friends who live in this part of the south hills area."
