Dr. Clarence Mast, MD

Dr Mast, has had Lymes himself and knows what its like. He gave me the right amount of antibiotics, vitamins, and diet elimination to get me back into normal daily life after being fatigued, itching, cramping, brain fogged for months. Wish I lived closer.

This Dr. “preys” on those suffering from Lyme disease. At the end of my hour long visit he offered to “pray” for my healing. Paid $500.00 cash for visit. None of the blood tests I gave were ever submitted for testing. Currently waiting for a return phone now for 2 weeks. Have left his office numerous messages. Don’t make the mistake I did in believing his snake oil sales pitch. He’ll have to answer to higher powers on his day of judgement.

So very glad i found Doctor Mast he is a gem and gives you the plan that helps the bands of lyme that you are suffering with after he runs your blood work. I was suffering so much with brain fog, joint pain, mood swings, head aches, fatigue, depression and many other symptoms. For years i suffered and was told i was going through the change of life that i had depression so i was put on many medicines that just caused me to gain weight and did nothing for my symptoms. Doctor Mast put me on a regiment and a food plan that caused my body to reboot itself and now i can do all the things i use to and i have the energy to get things done around the house and can think clearer and function so much better on a daily basis. Thank You Doctor Mast for being there for your patients and doing what you do best. Fighting this terrible disease and giving people a chance to live again. Bless You.

Dr. Mast saved my daughter in 2015. She had been misdiagnosed since 2013 from a tick bite in Kentucky. The doctors in KY kept pushing for lupus and fibromyalgia. Dr. Mast knew immediately from the markings on her body. He did bloodwork that we sent off an once all that came back he started her on the rest of the treatment plan to get her better. The entire staff was very good to us. An to this day my daughter is a walking miracle. 8 months in a wheelchair an today you would never know minus some aches every now an then. Diet change is a big thing so don't let infectious disease doctors tell you differently. They added more stress than help. Thank you Dr. Mast

He has really helped me!

Money grab specialist preying on those who are desperate for help. Should lose his license.

I wouldn’t recommend seeing him if you need to be treated for Lyme’s disease. He’s a fake specialist and lies about the necessary treatment methods. Don’t let him manipulate you. After being on medication for over a year that I’ve now realized I only needed for two weeks I’m disgusted to have ever spent a dollar towards his practice. The only thing that disgusts me more is the fact that I even have to give this review a one star rating. Do yourself and your wallet a favor and avoid his fake practice in its entirety.

I went to Dr. Mast from 1978-2003 until I moved to San Antonio TX. I can't find an MD here. I miss him and am ready to fly back just for an appt. He treated our whole family. Bless him.

I see Dr. Mast for Lyme Disease and NEVER have I been treated with such courtesy, interest and expertise. Having been shown the door by many other “specialists”, he is the only one that listened and understood my illness of the last 25 years. I love that he asks if he can pray with you. It creates a loving, healing energy and is not about religion or whom or what you believe in. I am grateful for this wonderful, compassionate doctor and human being.

This was our first visit for my husband. Dr. Mast took time to ask us questions, find out about my husband's health history, answer our questions, and gave us a lot of good information. We have not had a doctor sit and talk with us for this length of time, ever. He seemed genuinely interested in our concerns, and was very easy to talk to. He explained all his assumptions on possible reasons for my husband's health and gave us information to take home and read.
