What our patients say!

"Very professional and pleasing atmosphere! Dr. Hartzell took the time to conveying clearly to me what everything in my treatment meant. You can tell Dr. Hartzell cares for his patients, he displayed his knowledge and thoughts on my care and I felt safe in his hands and in the hands of his staff."
"I cannot say enough good things about Dr. Hartzell. He's an excellent diagnostician with great bedside manner. He was able to make a nervous patient like myself feel relaxed. He took the time to thoroughly explain everything, answered all my questions, and never making me feel rushed. Best of all, he created a treatment plan for me that literally gave me my life back! I no longer have any limits on what I can do, and that is all thanks to Dr. Hartzell."
"Dr. Hartzell is highly knowledgeable in all specialties. He is kind, considerate and extremely patient. I wish every doctor was like him."
"Dr. Hartzell is outstanding and takes his time with you. He practices medicine the right way. Also, he is very nice."
"Dr. Hartzell is compassionate, professional and really cares! I hope you don’t need to see him, but he was a God send to us when my husband had a mass in his left lung! You are in the best care with him!!!"
"Amazing doctor. After years of misdiagnosis he got it right and I am on the mend."
