Our Mission

Welcome to Hacienda Micro-Endodontics!  You have been referred to us because your dentist feels that you require the expertise of a root canal specialist. 

Our Mission is simple: to provide you with the finest endodontic treatment available anywhere. 

We strive to achieve excellence through compassion and innovation.  We offer comfortable and high-quality care that will help keep your natural teeth for a lifetime.  We are part of your dental team.

Welcome to Our Imaging-Directed Microscope-Centered Specialty Practice

At Hacienda Micro-Endodontics, we strive to continually elevate the standard of quality in endodontic care by utilizing the most advanced technology available.  Our office is a state-of-the-art Paperless Digital Office.  All patient records, radiographs and images are stored digitally in a secured server.  We also offer Online Check-in/Register at our website, so you can fill out all the necessary information at the comfort of your home prior to your first visit.

Cutting edge endodontic therapy is delivered entirely under the Surgical Operating Microscope with optimally enhanced visualization and illumination of complex root canal anatomy, allowing us to deliver the highest quality care and the most predictable outcomes for you.

Our office is equipped with a 3D CBCT (Cone Beam Computed Tomography) machine, J.Morita Veraviewepocs 3D R100, which gives more detailed image and higher resolution of the anatomy and surrounding areas when compared to the conventional 2D dental radiograph.  It can also target to a very focused field to limit the amount of radiation. With such powerful imaging advancement, we are able to perform treatment through a much smaller hole than previously possible, preserving the critically important tooth structure.  

We also use Digital Radiography and Digital Photography to effectively document and communicate with you and your dentists. 

We understand that you may be highly anxious about having endodontic therapy.  For the very phobic and anxious adult patients, you may be presented with an option to have Oral Conscious Sedation for your endodontic therapy.  An IV Sedation can also be arranged with our dental anesthesiologist after initial consultation visit.

From the design and color of our office, to the Tempur-Pedic dental overlay and neck pillow, we go to great lengths to make your visit as stress-free and as comfortable as possible.  It is not unusual for our patients to fall asleep during the treatment, or even during surgery, and we take that as a compliment.

Patient Testimonials

This is the most comfortable I have ever been in a Dental procedure. Mary has the hands of an Angel. The atmosphere was more like being at SPA than a dental office. The music is calming, there seems to be scented candles burning and they even whisper while operating. It was so calming that I fell asleep several times. I really enjoyed the whole experience. Mary and her staff are amazing. - Roger B.


Totally impressed with the professionalism and service that Dr. Chien and staff provided. The procedure was painless and I caught myself dozing off a couple of times. I would highly recommend dental procedures at this office. - Dell A. 


Great experience. Dr. removed all apprehension prior to procedure. One of the best dental experiences ever. - Henry P.


Dr. Mary Chien is a wonderful endodontist. After hearing horror stories of friends' root canal procedures. I was incredibly concerned about my own. But Dr. Chien was very comforting and made sure that I was never in pain. She let me know exactly what the process was, what should I expect after and insisted that I let her know if anything at all was bothering me before, during, and after the procedure. I did not experience any pain whatsoever. Dr. Chien is absolutely the best tooth specialist I have seen. - Ariel W.


Good Morning Hacienda Endo!! I wanted to take a minute out of my day to say how much I "Thank You". I am extremely pleased with the entire experience I had in your office yesterday. You and your staff honestly do deliver the highest quality care. I feel 100% better. I can't even begin to express my gratitude. God Bless you and I wish you and your staff a Happy New Year!!!  - Zoraida M.
