My family has been seeing Dr. Haag for roughly 14 years. Always very clean and conscientious about office hygiene. Office staff and Dr. very personable and they don’t over book. We have never experienced a wait time more than 5 minutes. Highly recommend.
We are not local to his office but it has always been worth the drive. Kudos to Dr Haag and staff all are gems.

Our family has been coming to Dr. Haag’s office for over 10 years. His front office staff is one of the best I have ever seen in a medical office setting. They are efficient, accommodating and extremely friendly. Anytime we have had to cancel and reschedule an appointment, the changes are made immediately. Dr. Haag is professional, thorough and personable. We never feel he is trying to create problems to increase the bill. Our teeth are cleaned (X-rays done as needed), exam completed, next appointment scheduled and we’re on our way.

Excellent experience. Dr. Haag and Arlene are very considerate and care about their clients. I am new to their office and Dr. Haag gave  me a straightforward answer to an issue and saved me $$$ on unnecessary dental work that was prescribed me by my previous dentist. I am pleased with their attention to detail and sound advice. The Hygienists Kira was excellent as well. Great job, will return here again.

Dr. Haag and his entire office staff are the best of the best. They make going to the dentist a pleasurable experience, where you don’t even mind going. I would not hesitate recommending Dr. Haag to anyone needing quality dental and orthodontic services.

We love Dr. Haag’s dental office! Whether we see the dentist or hygienist, we rarely have to wait, they understand that everyone’s time is important!!! Everyone in the office is kind, professional and very personable!!! I would highly recommend Dr. Haag and his staff to anyone searching for a dentist!!

Very clean office and friendly staff. I didn’t feel pushed, they listened on the phone to my concerns and needs. 24hrs later I’m at this office and the woman I spoke with remembered everything I told her the day before. Everything. That in itself is a first for me in any health related medical office. I’m 59yrs old. I’ve seen many doctors.
When I entered, Dr Haag was sitting at the front desk. He greeted me and asked me what was wrong? This was before I even created an account. This doctor is truly passionate about his job, and he cares about us! Great man. Honest man. Great experience for me.
Thank you Dr. Haag and staff. I will return!

I lived in Fullerton and Dr Haag was my families dentist. Never disappointed. Moving to a different county, we continued to commute because of his professionalism and knowledge and feeling so confident that the issues would be resolved. Unfortunately, due to my work schedule, we had to find a new dentist closer to home. But recently I was informed of a possible (expensive) diagnosis. Not convinced I knew it was time to seek the advice of our number one dentist and I am so happy that we did. We will commute to our appointments because of the confidence we have always experienced with Dr Haag. His staff is wonderful also!

I met Dr. Haag today at my medical office… we started off rocky but ended up with a very pleasant experience. THANK you Dr. Haha, as a person/patient you where very nice as a dentist I am sure you are amazing!!

Dolores R. from West Covina, CA (Source: Yelp)


Dr Haag is caring, gentle and great listener. I have sensitive teeth and have never experienced pain after a procedure. There’s been times where I didn’t even know he was done because it didn’t hurt. I am no longer nervous seeing my dentist. I recommend Dr Haag to my friends and coworkers all the time.

Diana N. from Fullerton, CA (Source: Yelp)


This place is amazing! I am really scared of the dentist and have been known to have panic and anxiety at the doctors due to my past experiences. This doctor is very patient and spends a lot of time explaining everything you need to know, it doesn’t matter how long it takes. The staff that works with him are fantastic! I was so comfortable they could have started doing a procedure right there in the chair! He is now the dentist I will be seeing. Thank you to the whole staff and Dr. Haags for everything. You gained a patient because of my experience!

Dr. Haag and his staff are very professional. You can tell they all get along great. Everyone is so pleasant. I trust Dr. Haag. He is honest and caring. He doesn’t try to sell you something if you don’t need it. My whole family sees him. Kids and all.

Bell V. from Riverside, CA (Source: Yelp)


Love Dr Haag! I can’t imagine going to another dentist. Been with him 20 years!! His staff is great also. Just wish he would be open on Friday.  But, good for them to have a three day weekend.

Wendy F. from Fullerton, CA (Source: Yelp)


Woo hoo! Dr. Haag is as good as it gets, seriously! He has taken care of my family forever, it seems. He’s so caring, smart and funny, that going to an appointment is FUN. Plus, he’s the most caring and dedicated dentist–always available for emergencies. Walking into his office is like walking into a trusted friend’s home. The office staff is as committed to patient care as Dr. Haag. A+

Jeannie M. from La Habra, CA (Source: Yelp)


Dr Haag and staff are awesome! My cleanings are so gentle (but thorough) that I actually fall asleep. The front desk staff is so friendly and patient with all the rescheduling and payment reminders. Dr Haag is very knowledgeable, professional, and proactive. We always feel like we are genuinely being taken care of without pressure to do unnecessary work. Highly recommend Dr Haag and his staff.

Paul G. from Orange, CA (Source: Yelp)


I tend to be a tough reviewer and in the past I had a bad run of dentists but, Dr Haag is amazing. I have never experienced such excellent treatment or service. I really cannot recommend him highly enough. This last visit I had a new hygienist, Brianna and she was incredibly diligent and thorough as well as being very concerned for my well being (I may or may not be a bit of a baby about dentistry). Good job

In went to see Dr. Haag for a consultation and possible change in practitioners on the recommendation of friend who along with her family, have been patients of his for years and recommended him highly. In addition to this, I was impressed with his background and training.  I found Dr. Haag to be extremely professional, thorough, responsive and overall most helpful in his evaluation of my particular situation.  I also was very impressed with the friendly efficiency of his staff, even before I arrived and the general sense of how they all work together for the benefit of their patients.

Diana R. from Rancho Mirage, CA (Source: Yelp)


I have been going to Dr Haag for over 25 years and I am now retired and living in the Rancho Mirage, ca.  Even though the commute is 2 1/2 hours one way for an appointment, I wouldn’t ever consider changing.  The entire staff is great!

Brian P. from Fullerton, CA (Source: Yelp)


I have been going to Dr. Haag’s office for over 4 years now, and I have had nothing but great experiences there. The staff is very friendly and has made me feel comfortable (Yes, a dental office made me feel comfortable). The Hygentist there who cleans my teeth, Beverly,  always does a thorough and excellent job! I would Highly recommend this office.

Whitney F. from Costa Mesa, CA (Source: Yelp)


Can’t say enough good things about this office. I have been coming here since I was a teenager. I lived on the East Coast for 15 years and refused to get another dentist. I managed to come see Dr Haag twice a year for my cleanings and checkups. Everyone is wonderful here from front desk to hygenists to Dr Haag himself.

Dr Gordon Haag is the absolute best. He really does go over and beyond in helping you achieve the greatest smile. I trust only Dr Haag and his staff. Thank you for all that you do because going to the dentist isn’t my favorite thing to do.

Solid dentist with no nonsense approach and perfect execution. Was lucky to be in his chair after a recent dental emergency. If you’re looking for someone who knows what they’re doing and treats without fuss or fanfare, come here.

Dave K. from Irvine, CA (Source: Yelp)


I popped off a crown on Sunday and called my regular dentist Monday morning who was on vacation for thanksgiving week. The emergency number led me to Dr. Haag’s office. His staff worked me in that very afternoon! Much appreciated! Dr. Haag and his staff from the receptionist to the assistant and Dr. Haag were all friendly, concerned and professional. I would highly recommend them to anyone in search of dentist and would go back in an instant! Thanks for the great job and getting me on my way quickly!

Steve H. from Westminster, CA (Source: Yelp)


Members of my family have been going to this office since 1972.  They have always been friendly and treated us well.  They look out for their patients even beyond dentistry.  I will always respect how they have looked out for my family over their business needs. Thanks for being there.

Sherry B. from Norco, CA (Source: Yelp)


This Dental Office has the best staff and Dentist ever. Dr. Haag is an extraordinary Dentist and his Staff are the nicest gals. They really genuinely care about each and every patient and do outstanding dental work. To be honest, I cannot say enough about them. Thank You Dr. Haag and Staff!!

Hilary S. from Brea, CA (Source: Yelp)


Now that I have been a patient of Dr. Haags for over a year I am excited to tell everyone about this fine establishment.  First, for general dentistry his office is thorough and trustworthy.  They will give recommendation for treatment but are very honest if you have the option of waiting and watching.  I like that they are not pushing unnecessary treatment. Second, I have been working with Dr. Haag to straighten my teeth and I cannot begin to express how impressed I am with their excellent level of care.  He has been working with me to get results and I appreciate his positive attitude and capable spirit.  I have had some bad experiences with other dentist in the past but this office has been a game changer.  If you are looking for a new dentist, look no further, you will not be disappointed.

One of the best dentist I have ever been to. The entire staff were so nice and helpful. They are honest and very knowledgeable. Gordon is such a nice guy, not to mention a very entertaining gentleman. I must have laughed a hog dozen times. You don’t even realize you are at the dentist. I highly recommend Gordon Haag and his wonderful staff of employees.

I’ve been going to Dr. Haag for years. I love the staff. They are courteous, friendly, and bend over backwards to accommodate my needs. Dr. Haag even came in on a Saturday to help me. The office goes above and beyond to help patients out. Thank you Dr. Haag & Staff

Justin W. from Chino Hills, CA (Source: Yelp)


Simply put, Dr. Haag is phenomenal. I have been going to him for almost 15 years, and I would never consider going to another dentist. In fact, I now travel about 25 miles to see him. He and all of his staff are always extremely friendly, and he is an absolute master of his craft. He also has a wonderful sense of humor, which I always appreciate. If you are reading this, stop looking for other dentists and pay him a visit. You will not regret it.

Chris Y. from Fullerton, CA (Source: Yelp)


Very clean, professional Office. Staff very courteous and always willing to educate with any dental questions I had. Very happy with my teeth cleaning and they feel very smooth and clean. They made great recommendations on Personal dental care items such as my new Sonicare Toothbrush and Water Pik flosser. Their recommendations are really keeping my reel cleaner than they ever been and I’m very happy for that. I also wanted to send Dr Haag and his to a very big thank you so the world can see for what they did for my father before he passed. My father towards the end of his life was having tooth pains and due to his illness most dentists wouldn’t even perform the procedure necessary to alleviate the pain. Dr Haag not only fixed the problem but also sent my father home dental pain free. Thank you and the team have myself and my family’s business for life.

Comment: My family and I have been going to Dr. Haag for over 30 years. He is a real professional who cares about his patients. He has a wonderful personality and this translates to his staff as well. His staff are all top notch people that are efficient and helpful. I highly recommend you try Dr. Haag.

Bjorn R. from Los Angeles, CA (Source: Yelp)


The appointments I’ve had at Dr. Haag’s office have been great. From the front desk and hygienist’s to Dr. Haag himself, I’ve always felt welcome and in competent hands. Everyone seems to puts out the effort to make me feel at ease and fill me in on what’s going on inside my mouth. They go beyond a simple, “are you flossing?” ( that’s a no, just in case you were wondering) and really walk me through what they are seeing and break it down for me in a way I can understand and use at home. Scheduling appointments is always a breeze and when I arrive I’ve never had to wait very long to be seen — I appreciate that they use the time I take off of work thoughtfully.   I’ve recommended their office before and I’d confidently do so again.
