    Great dentist who offers sedation for anxious patients. Also open on Fridays and has last-minute appointment availability for emergencies.

    Be careful of this dentist, I would never go here again. When being referred from other dentist…read moreoffices, he charges a separate evaluation, which is normally waived by a referred office. Also, gave an estimate of $220.20 for procedure after they "stated" they checked with insurance. Insurance has NO RECORD of any calls from this dentist office. The estimate ends up being DOUBLE or $432.20 because they didn't factor things in from the insurance company, had the actually contacted them, would have determined. I got an "I'm sorry" this happened, that's how estimates work with dentist and medical field. And WE Don't have time to spend all day talking to insurance companies. REALLY?!? Isn't that exactly your job. It took me 5 minutes to find out YOU didn't make the call? So even though nothing was MY fault. I'm stuck paying DOUBLE what they estimate? And what kind of estimate is DOUBLE in cost anyway. I can actually see being off $10, $20, or even $50, but DOUBLE $212?!? Very poorly run operation which is more concerned with $ than accepting responsibility of being wrong.

    Wanted to thank Dr. Zimmerman and his staff for a job well done! He was recommended highly by my…read moredentist and several past patients agreed. I was not super excited about having to have a much needed procedure but he provided excellent education and reassurance. He and his staff have great chair-side manner. Had I known it would have been such a great experience I would have come in sooner - FIVE stars for evaluation, procedure, recovery, and follow-up! Thanks Powell Endodontics!
