This man saved my life when I had no idea what was going on at the time. The staff have been extremely respectful and courteous, not only to me but my family when 5 of us came at one time because they wanted to know too and he took the time to explain to them as well. Everyone is so helpful anytime you have a question or concern. I recommend Dr. Deleon to anyone who asks me where I go because his office and him are the best as I have had several bad experiences at another place.

Dr Mark DeLeon is caring. He takes his time with us on every visit and explains in detail everything going on with chemo treatments. He does not just throw medical terms but explains in Layman’s terminology so we can understand. There have been numerous times when he has called way after hours to share and discuss results. We are very lucky to have Dr DeLeon so close by. Everyone in the Frederisburg Texas Oncology clinic is amazing. They are making this journey bearable.

I've been a regular patient at this clinic since 2014 and am currently being treated for metastatic breast cancer and osteoporosis. I have always found Dr. DeLeon and his staff to be professional, competent, compassionate and caring. They're the best as far as I'm concerned.

Be very careful with this Dr. and make sure you get a second opinion. He is very quick to make a judgment call and put someone in hospice without a fight.

Dr. DeLeon has treated my multiple myeloma for 10 years through several relapses. I have now been in a near complete remission for almost one year. He listens intently to my concerns, is compassionate in his treatment approach and his office is truly one of the most organized medical offices I’ve experienced. The chemotherapy/infusion nurses are particularly awesome. God heals through worthy individuals; I consider myself a miracle due to the treatment of Dr. DeLeon and staff.

This doctor only cares about how much he can get from medicare or treatment kickbacks. They ignore treatment protocol and adverse reactions just to keep billing medicare. When a treatment was making my father much worse and he said he no longer wanted them, they threatened his life. He would die if they did not treat him. Don't let them kill your loved ones.

Dr DeLeon and staff treated my wife post cancer for 3 years with opioid pain medications then treated her like a criminal when she returned for assistance when current step down treatment wasn’t working. The PA threatened to call the police on my 102 lb wife, not looking for Opiates but looking for help with managing the step down. They’ll get you hopped up on meds and leave you in the cold figuring out what to do. Thanks guys. You should be ashamed of yourselves. Love to see your response.

Dr.Deleon treated my wife for throat cancer and then lung cancer. Both times during this worrisome time,he made us feel that there was hope. The staff and nurse's were very caring and showed compassion.We never left the office without any questions unanswered and fully explained in terms we could understand.Today, 4 years later she is still cancer free and we can thank him for it!
