I have been a patient of Dr. Frieden's for over 10 yrs, and have been very happy with him. I have referred friends and family to him, and they have been pleased, as well. He does hygienes/cleanings himself, rather than allowing a hygenist to do the work. He is good at explaining what he will be doing and making sure the patient knows what to expect both during and after a procedure. He has also provided me with referrals to a very good dentist while I was out of town and needed work done, and to a very good oral surgeon when I needed an extraction.
