Duane B. Gustafson, DMD and Gregory K. An, DDS, MPH

I went in for a last minute root canal today and I don’t think my review will do justice for Dr Gustafson, you just have to go and see how good he is for yourself. He is super friendly and makes you feel at ease. He has a gentle hand and makes sure you are 110% comfortable during the procedure. He let me know what he is doing to my tooth and even cracked a few jokes while he was working, which made me feel much more relaxed. He would also put a good amount of vaseline on my super dry lips! You can tell Dr Gustafson is a pro at what he does and he genuinely cares about his patients. Hours after my appointment I got a call from Dr Gustafson and he asked me how I was feeling and gave me a few tips on how to manage the (very little) pain I had. Id give 6 stars if I could because he is just that good at what he does. I would happily recommend him to anyone!

I was so scared going in. This was my first root canal. Everyone in this office is sweet, attentive and patient. Dr. An is wonderful. He kept asking me if I was ok and you can tell he truly cares about his patients. Root canal was a piece of cake. My fears are now gone. I walked out with a smile on my face. I highly recommend these awesome people.

I am so grateful to Dr. An who took me on an emergency referral and gave me a same day root canal. I’m sure he was at work later than is normal, but he was thorough and informative and I never felt rushed. His work was meticulous. Best root canal I ever got! I am 100% confident in his work.

Dr. An was gentle, patient, and thorough. My root canal retreatment took 2 hours but I knew it was because he was trying to do the best job possible. Throughout the procedure he was asking whether I was ok, if I was comfortable, if i felt any pain. He patiently answered all of my questions and was in general very kind, with an excellent bedside manner. I didn’t feel any pain and generally felt at ease. The office is clean and tidy and all personnel are very friendly. Highly recommended.

Since I found Dr Gustafson on Unilocal I thought I’d follow up with a review so other people can find him too! I had my root canal
done today and it was such an easy procedure. I laid back and just closed my eyes half the time because I was so comfortable. Zero pain! I didn’t even feel the shots. (:
oh and the goodie bag in the end is adorable!

This review is WAY OVERDUE! After leaving from having my Root canal done and all numb I can truly say that I have had a great experience. If I can give then 10 stars I would! Like really!
Office area is small but very welcoming when you walk in! Everything is so clean and tidy!
I came here last year May 2014 as my past dentist sent me here for a root canal. I was surprised to see how quick I was able to get an appointment in. I spoke to the Office Assistant Mary Lou, who by the way, is always SO pleasant to speak to over the phone. Even with my busy schedule she was able to fit me in for an appointment.
She scheduled me for an appointment with Dr. Gregory An and as I was extremely nerves he made sure to make me feel very comfortable. Let me just admit that the chairs are SO comfortable and I felt well relaxed. I have to admit I was almost falling asleep!
6 months later I was back in Dr. An’s chair getting the root canal re-​treated. I was nerves once again and didn’t know if the experience was going to be as the first one or painful. But little did I know it was a piece of cake.
What really meant a lot to me is that they still were able to accommodate me even after being 40 minutes late for my appointment this morning. Okay. so I am not ALWAYS early to my appointments but as traffic was insane and I couldn’t do anything about it I still was able to get my root canal done today. Usually, many places would say, «sorry, but as we have appointments all day, we would have to reschedule yours.» Nope! I didn’t hear that from Mary Lou at all! :) How amazing is that!!! That really meant a lot to me! Big thank you to Aida the assistant for Dr. An, for supporting me the whole time I was in the chair and making me feel comfortable. The reminder of me doing a great job was big to me! Shout out to the Insurance Specialist– Maria! Her smile is always so charming! :)
So as you may know now, this is surely the place to come if you are in need of a root canal! They do amazing work and you would NOT be disappointed! Thank you Dr. An!!!

Great experience in getting a root canal done.
I was referred to Dr Gregory K An for a root canal and have nothing but good things to say about him and his staff. They took care of my tooth, followed up with phone calls to make sure I was doing well and scheduled a follow up apt to be curtain everything was done right. The procedure took 1 hour and was painless. Dr An was very gentle and explained everything very clearly. To say a root canal was a pleasurable experience must indicate he is the doc to go see if you need one done. Thank you Dr An.

Dr. Gustafson was highly recommended to me. I had several apicoectomy procedures done in the past and it was always painful as I am resistant to dental anesthetics. I mentioned it to Dr. Gustafson and he performed 2 apicoectomy procedures at once. It was painless and I had minimal swelling the day after. Dr. Gus even called me in the evening to make sure I was doing fine.
Dr. Gustafson is the best!!!

My dentist referred this place for a root canal. They immediately put me in an appointment for next day. Dr. An did a fabulous job. The whole procedure is painless. Dr. An was very detailed and explained what he was doing during the procedure. I came out of his office in 1.5 hr. My life went on without any tooth pain. And I received a phone call from Dr. An at night checking on my tooth. It was a very pleasant experience.

Superb. the best there is. no pain,…absolutely the best there is!

There is a very good reason why everyone has given Dr. Gustafson 5 stars ++. That’s all I need to say. He is worth every star and every ++. Without a doubt, if you need his services do not hesitate.

This is such a fabulous man — both as a person and an endodontist. He explains the work, shows you what he is going to do and he does it quickly and very well. I went elsewhere in the past and it was not nearly as good as Dr Gus.

It’s well over time I update my review for Dr. Gustafson. Please sit down, read close and enjoy the ride.
Today I went in for my 11^th root canal. My teeth are a complete wreck and at this point there are only a few select people I feel comfortable working on my mouth. As far as root canals go, I would not want to go to ANYONE other than Dr. Gustafson. My last review proves how appreciative and fond I am of him but every time I go back I am more impressed.
Today I decided to be very observant from the time I sat in the lobby to the time I the dental room where he worked on me.
I want to point out some things I noticed that need recognition. The first is the lobby. It is GORGEOUS. Whoever decorated it is brilliant — the paint, colors, light stand, desk, beautiful contemporary chairs and best of all the art work on the walls. It all matches into a comfy oasis of a lobby. Little did I know the art work is all Dr. Gustafson’s personal photography work! My jaw dropped to the floor when Mary Lou (his wonderful receptionist who is as sweet as a summer peach) told me he took the photos. They look like professional photo-​paintings. Dr. Gustafson is a man of MANY talents.
Next thing I noticed as the phone rang and someone needed an appointment was how quickly they are able to make appointments. I have noticed this with my own appointments and even though he is a busy man they always find a way to fit you in as quickly as possible… sometimes NEXT day and you are on your way.
Other things that have not changed and most likely never will: the friend and positive attitudes, the smiles, the way they make you feel cared for in there, the care kits they give you after with the bonus kit kat bar included, the comfortable memory foam chairs you never want to get out of, his playful humor the way he patiently talks you through your procedure, the skill, knowledge and experience he has to get whatever job or challenge he is faced with done so you are out of pain, the «good work» comments you get after the procedure and the great after call gives you himself in the evening to make sure you are okay even though it’s his time off and he should be home resting after a long day. He still makes time to call his patients who came in that day; a true example of selflessness.
There are also the those special «little things» Dr. Gustafson and his assistants do to make your procedure as comfortable as possible — the vaseline on the lips so you aren’t desert lips, the pillow placed behind your neck so you aren’t stiff necked, the kind offer of a blanket so you aren’t cold or magazines so you aren’t bored… little things become big things to the person who is in pain and there to get relief. You feel nurtured and that’s exactly how you want to feel. TRUST ME.
You will get that relief and so much more here. People like this are really important to me. There are the kind of caring souls I wish I had friendships with outside the office. They will not fail to make you happy no matter what grumpy condition you come in with. Other patients are just as thankful. I lost count how many times I heard «thank you» from clients before me and during my short break in the chair. This just validates that I am not exaggerating this review with some over the top thoughts. Please believe me when I say that I write this review from my heart.

Great guy who does amazing work. He made sure the process of my root canal was seamless. He even indulged my curious side by explaining step by step what he was doing, what chemicals he was putting into my mouth, and why it was going to help. Very efficient and really great at giving anesthesia shots (they barely hurt, and trust me, I’ve had a lot in my life!)
Really nice staff, really nice guy and they easily re-​filed my delta dental insurance claim when delta dental screwed me up and gave me the wrong card.
The thing I love most about Dr. Gustafson is that he called me the night of my procedure and asked me if I was feeling alright and if the pain was manageable! Five star service for sure.

Dr. Gustafson and his office staff are absolutely delightful. My whole root canal experience, from calling the office making the appointment to having the root canal done to paying my copay was a pleasant experience. I recommend Duane Gustafson, DMD and his office staff highly.

I was frightened when I heard from my dentist that my nerve was dying, which was yesterday morning. So he referred Dr. Gustafson as a root canal specialist and asked me to call him as soon as possible. I called, they immediately put me in an appointment for right next morning, which was today. I couldn’t sleep for days due to sharp pain not just inside of my gum but just to all over my face to the sharp headache. Next to contraction, I can count this as the comparable pain I have ever dealt with.
That point, I was willing to see anyone who could help me out. From the receptionist, very knowledgable Dr. Gustafson’s assistant, *very caring, compassionate, loving, world class top notch dentist, Dr. Gustafson. I was expecting the worst case scenario where I wouldn’t be able to eat, function at work and at home, drive, etc. My coworker said that I am like a person who just came out of cleaning teeth, not from root canal. :) After coming back home, I could smile.
I just met a miraculous life saviour, Dr. Gustafson. He also called me 40 minutes ago and made sure everything was going ok with me.
He is the role model to any doctor, no. to any human being.
Thank you, thank you, thank you, Dr. Gustafson!

Best Dental Experience Ever!
Dr. Gustafson and everyone in his office are very friendly and professional. I was so sure that this was going to hurt but I got through the entire root canal with no pain. No pain! He kindly explained what he was doing through the whole procedure. Everything went smooth and I was out of there in no time. I went back to work directly after and haven’t felt any pain since. That was easier than an annual cleaning! I couldn’t be more satisfied.
I highly recommend Dr. Gustafson for root canals.

It is odd to write a raving review about a root canal. But Dr. Gus and his office are fantastic.
I had to get a root canal yesterday morning and I was surprised that it only took 1.5 hours and also that I had no pain during the procedure. Dr. Gus has a very good understanding of where nerve endings like to hide and covered all the endings I had so well, I had zero discomfort.
I was very glad for the goodie bag the office gave me as I was leaving and the instructions were very clear. I also really appreciated the follow up call to see how I was doing later in the day.
I hope I do not have to have another root canal but if I do I know where I am going to go for it.

A 5 star rating is an understatement, Dr Gustafson and staff go far and beyond the call of duty. Dr Gustafson is very thorough. He was very detailed in his explanation about why I needed an apoectomy. You could tell he truly cared about all his patients as he was highly recommended by others.
For those who don’t know, apoectomy involes slicing the gum to gain access to the root and clearing the infection, that means breaking thru bone and all. Afterwards they stitch the gum. Sounds very painful however with the expertise, calmness and attention to detail Dr Gustafson gave, the procedure was a breeze. Ive experienced more pain during previous fillings from other dentists. He really made sure I wasn’t having pain during the procedure and always asked If i was ok. I couldn’t believe I didn’t experience any pain during the procedure.
I never thought I would be raving about a Dentist who just sliced my gum open. Its approx 9pm and I had the procedure done earlier. I just received a call from Dr Gustafson. He was checking up on me making sure everything was ok. WHO DOES THAT? …Amazing service. They have earned our business for life, too bad I can’t use them for our regular Dental needs. I can honestly say, I am no longer afraid of root canals and wisdom teeth removals.
If you need a good endodontist, look no further.

I was bummed to learn that I needed a root canal. My dentist highly recommended Dr. Gustafson as the best and said that it’d be painless and take about an hour.
I had my root canal this morning and it didn’t hurt. I’m glad to have found a skilled and super nice endodontist. There was a memory foam cover on the dental chair to make it extra comfy and they put dark glasses on me to protect my eyes. As I left, I got a little gift bag with follow-​up instructions and a few goodies.
I hope I don’t need additional root canals, but if I do, I’ll definitely return to Dr. Gustafson.
