    Always wait at least an hour to be seen. And apparently according to his staff he sees his elderly patients b4 others so they aren't inconvenience.

    Dr. Folan allows his assistant Kristine to issue prescriptions. Kristine Recently prescribed for my recently widowed, 79 year old mother whi has had a heart attack, heart surgery, further heart complications since & high blood pressure ~> all while under Folan's care. My father always did say Folan was a quack. Are they stupid or do they just care more about $$$ than people???

    I have been a patient of Dr. Folan for maybe 20 years and to this day trust him to the fullest. His staff as well as himself have helped me thru some very difficult medical situations and always willing to help and advise the best specialists. Have recommended him to several family members of the years and they also continue to see him. Excellent Doctor and would recommend him to all adults. Very thoughtful, courteous and thorough. 5 Star Doctor !
