Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

After numerous appointments for all my husband symptoms. Watching him decline rapidly. One of his clients recommended Dr. Clarence Mast. Within an hour and half appointment . Dr Mast had my husband on a regime, see my husband didn't just have Lyme he was dealing with 3 of the tick borne illnesses. It took almost a year but the difference is truly amazing. My husband and I are truly blessed to have found such a great doctor. We can not thank him enough.

After spending 2 years very sick with an unknown illness, and seeing 2 dozen drs, I was done and had given up hope. Then someone suggested Dr. Mast. I'm so thankful I went to him! He saved and gave me back my life! After treatment and I was pain and symptom free! I'll forever be grateful for his care.

I’ve had some horrible experiences with LLMDs so I’m always nervous to see another one. Well Dr. Mast put all my anxiety and fears at bay. What a nice, sweet and kind man. He took the time to listen and explain everything. I adore this man. God bless him for his willingness to help the suffering in such a gracious and humble way.

I have been seeing Dr Mast for over a year. He was the only Dr able to diagnose a 30 year infection of Lyme and 3 other tick borne illnesses. He is very knowledgeable and has an excellent bed side manner. He listens to his patients and takes the time to explain treatments and symptoms. You may have to wait a while in the waiting room but it is because he takes the time with his patients. He is the best of the very few LLMDs in our area. His staff is very friendly and always helpful.

DO NOT MAKE AN APPT UNLESS YOU PLAN ON SPENDING THE ENTIRE DAY THERE. I walked out after traveling 2 hrs + waiting 2.5 hrs only to be told "I'm not sure when the doc will be able to see you" when I asked how much longer it would be. Come to find out there were 5 people ahead of me! It's disgusting that we wasted hours driving, gas and sitter expenses. So inconsiderate! BEWARE! And this is normal according to another patient, he routinely waits anywhere from 2-4.5 hours!

Treated for Lyme. Excelent results, but you have to follow what they tell you if you want to get better. Staff is busy but always available. Dr is kind and commited. Would highly recommend him.
