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.

Dr Mathern and his nurse, Nancy Foreman, are the best. They go above and beyond, are thorough, they listen, they take the time to explain, and the appointments aren’t rushed. Great quality of care with them.

This office needs a blood lab for quick results. Many patients come from miles away since this is the only oncologist in a large area. Having to make 2 appointments, one for labs and another for doctor visit and treatment is a burden to patients.

Office staff is rude, brusque and unprofessional
Another doctor referred me to Dr. Mathern for blood monitoring and treatment. The front desk made no attempt at a hello or any warm greeting that you might expect, especially in an office treating cancer. They accepted my referral papers and without even looking at them told me that he was back from vacation, therefore behind and I’d be lucky to see him in three weeks. My condition required immediate and frequent lab work. It doesn’t appear that there is any interest in accepting new patients.
