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.

Great staff, Dr Dresen has been taking care of our family for 16 years. He is very professional and caring.Would definitely recommend .

Dr Dresen is caring and compassionate. He spent time with me, listen to all my concerns, discussed collaborative treatment and made me feel very comfortable with my choice in cardiologists. The office staff, Kathy, Lisa and Rhonda were wonderful. They demonstrated complete competency in their roles, they are professional and friendly and all have a great sense of humor, It was a real pleasure to deal with them.

As an RN who grew up I a medical family, I feel very qualified to say this is one of the best physicians I have ever known. He truly likes people, and it shows. His judgement is superb and he saved my husband's life by sending him for a test when he had no symptoms, while he was having a silent heart attack! He found a tumor in me that other doctors had missed for many years. His referrals to other doctors for other conditions has been outstanding. I trust him completely.
