I have been a patient of Dr. Flachs for almost 20 yrs. He still continues to treat my children even though they are all grown now. We all trust him with our health implicitly! Not only can we count on his knowledge & experience, he respects his patients enough that he does not “overbook” or have you sitting waiting & waiting ( which seems to be a given most medical facilities) I have NEVER waited more than 15 minutes . And that is unusual- it’s almost always exactly my appointment time!!!!! That is respect for the patient & their time! During the visit, he is just as respectful, concerned with the issue at hand and dedicated to helping you feel better. Dr. Flach’s office staff—especially Diane— are lovely, courteous, kind professionals, as well. My family and I thank you all!God bless you!

Extremely rude person. Does not listen to patients' opinions. Beware of double billing.

Does not care about the welfare of his patients. Has a superiority complex. Overall we have had a terrible experience with this man. Look elsewhere.
