From the time we came in, they were very cordial, the introduced us to Dr. Garren. He immediately has a smile on his face. He said, "Lets talk". He explained everything, and did not leave anything out. He is very positive, professional doctor, and more importantly, he gave us hope. He has not let us down and he has gave us our life back with a purpose and direction. I would recommend him to the world in a moment, he is a saint!

I am a new cancer patient, and I'm very happy with the treatment I'm getting with Dr. Garren. I'm currently at the Landmark Cancer Center at Oklahoma. He is a very busy man, but he has given me immense personal attention and care. His personality is different than any medical doctor than I have ever had, and I am appreciative of his care.

Dr. Garren is a consummate professional with immense knowledge, integrity, warmth, and kindness. He diagnosed my father with cancer after several other doctors overlooked it and took immediate action in ordering exams, procedures, and a treatment plan. He constantly followed up, continually put our family at ease, and consistently went beyond the call of duty, such as when he made home visits to assist with putting compression wraps on my father's legs. Simply put, Dr. Garren is world class.

Horrible.Arrogant and snip.In consult said I don't know what you want me to do with an inoperable brain tumor prior to explaining prognosis.Stated he was writing a book with a friend about patients with terminal illnesses and said he would commit my parents golden retriever's name to memory.Yet my father had to spell out his last name to Garren for recognition for medical necessity. I would never recommend him to another.No bedside manner considering his fake interest in the patient and family
