Check out what some of our happy patients are saying about us:

I recently went into Dr. O’Connor’s office for a long overdue check-up/cleaning. I was truly impressed with the service I received. I have high anxiety when it comes to dentist offices and have tried several.  I figured they were all the same and that it’s something you just have to deal with. Turns out there’s a world of difference when you find a great dentist. My entire experience was great and pain free. I really appreciated the genuine care and honesty of the staff. They break down every procedure and focus on getting your mouth healthy. I enjoyed my consultation with the dentist and hygienist who took the time to really talk to me and explain it all. I highly recommend this dentist and will share this rare find with everyone I know. FYI they also have TVs in their patient rooms!! You will not find another dentist or support team better than this!

Hands down the best. He explains everything and does great work. I have complete confidence in his work. His staff is also wonderful. They all work as a team. So glad I found this office a couple of years ago.

Great Dentist, great staff, great office. Like most I have been going to the dentist for decades, and Dr. O’Connor is the first and only dentist I have never regretted visiting. In my opinion, he and his staff are very friendly and very honest and never try pushing dental work I don’t need. My family and I switched to Dr. O’Connor about 5 years ago and have all been very happy.

Mike G. from La Habra, CA (Source: Yelp)


(…)Dr. O’Connor is probably the best dentist I’ve had in my life. In fact he is the first dentist I chose in my adult life. I had a bad experience when I was a kid and neglected to go to a dentist for years.
(…) I chose wisely, any fears I had going in were immediately put to rest. Just by listening to him talk, you can tell he truly cares for his patients. He explained to me what needed to be and how many appointments I would need.
I had some work done to fill some cavities, and I felt nothing at all. He was also quick and efficient. His front staff are truly nice people and his assistants are awesome too.
I’m glad I decided to choose him as my dentist and I honestly couldn’t recommend him enough.
If you are like me and haven’t been to a dentist in 10+ years. Trust me the good Doc will take care of you.

Everything with Dr. O’connor is a home run!  He is the best dentist hands down that I have ever had.  He fixed a gum problem I had for many years that nobody else could figure out and has done excellent work on my crowns and fillings.  He also has a great personality and is a lot of fun to talk to.  His staff is excellent and they put up with hours of cleaning coffee stains off my teeth with a smile.  I have been seeing him for about 5 years now.  My wife also sees him (well not that kind of seeing him or at least I hope not) for general dentistry –  she had a serious case of the snaggle tooth.  Dr. O’Connor set her up with Invisalign and within 3 months her teeth had changed dramatically, she is halfway through the treatment and her teeth look fantastic already.  We both highly recommend him for Invisalign, general and cosmetic dentistry.  They even have free coffee and a there is a Rocky Mountain Chocolate Factory next door, both of which will keep you a happy customer of Dr. O’Connor’s for years to come!

Jan B. from La Habra, CA (Source: Yelp)


I’ve been a patient for about 10 years. They have a great program for patients without dental insurance (…). The doctor has been good about telling me my options and the probable outcome and letting me make the decision.

Lis K. from Corona, CA (Source: Yelp)


I’ve been going to Dr. O’Connor for 8 years. He’s simply the best! The office staff is always so friendly and helpful too. I would (and have) recommend Dr. O’Connor to anyone in a heartbeat!

Lynda C. from Los Angeles, CA (Source: Yelp)


(…) My daughter has seen him when she was 13 yrs. old when she chipped her front tooth! :/ He preped it down and put I think a veneer/cap (?) and she is TURNING 30 YRS. OLD in Dec. and it STILL LOOKS AMAZING!  Thank you Dr. O’Connor! (…)

Shannon H. from Whittier, CA (Source: Yelp)


By the best dentist I have encountered.  The office is clean, the staff are friendly and above all, Dr. O’connor is honest and fair.  My aunts, husband and I have found a real gem and feel so blessed to have found this office.  Give him a shot, I promise you won’t be disappointed.

Robert C. from Corona, CA (Source: Yelp)


I cannot say enough words about this dentist, he made me feel very comfortable along with the staff they are a winning team,  I had some work done on me, after he was done  I had very little to no pain at all. I highly recommend him to my family and friends.

Helen C. from Pennsville, NJ (Source: Yelp)


Dr. O’Connor and his staff couldn’t be any nicer. By far one of the best dentists and most gentle that I’ve been to in my 61 years (…).

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


Unbelievable! The staff and doctor are absolutely amazing. (…)Dr O’Connor is amazing and will only be honest with you. He even called me to check up on me post root canal temporary crown. He also had a sense of humor. Love that!!!! His staff are so sweet and go out of there way to make you feel as though you were at a spa. Thank you all who cared for me. My hygienist was amazing too. Can’t say enough about the great service I received!

Ken Hopkins (Source: Google)


Dr. O’Connor and his staff are the absolute best!!! Since switching over to his office, I no longer dread going to the dentist. The Hygienists, Front Office Staff and assistants are always so friendly and go out of their way to make sure guests are treated with the utmost care and respect. Each treatment room is clean, completely private and includes a dedicated TV to help pass away the time.

After a thorough cleaning and a report of zero cavities, it was time to address a cracked tooth and prep for a crown. Dr. O’Conner’s handy work is second to none. He had a temporary locked in place in no time with zero discomfort. He really has dentistry down to a science. Bottom line, if you’re looking for a great dentist with state of the art equipment and friendly staff look no further. It’s worth the drive…

Tony M. from West Covina, CA (Source: Yelp)


Myself and family have been under the care of Dr. O’Conner for over 25 years. The past and current staff has always been professional, courteous, and caring.
A true reflection of Dr. O’Conner himself.

Margaret H. from La Habra, CA (Source: Yelp)


I came to this dental office in a recommendation from a friend looking for a second opinion (…). Dr O’Connor’s office was very friendly and accommodating. He did a thorough exam and found no reason for a bone graft. I was completely comfortable there and I’m sure glad. I will now be seeing Dr O’Connor and his staff. My family will be going there too!

Grace K. from Victorville, CA (Source: Yelp)


My family has been going to Dr. O’Connor for over 15 years, and we live over 50 miles away.  It is well worth the drive to see a dentist we trust.  His staff is always helpful and kind, willing to work to get us in when emergencies occur.  Dr. O’Connor himself takes a conservative approach, never pushing unnecessary procedures but always being honest and straightforward about things.  And he’s unbelievably upbeat!  I recommend wholeheartedly and enthusiastically!

Lin Z. from La Habra, CA (Source: Yelp)


Dr O’Connor has been taking care of my family and I  for years. He is thorough and efficient. You won’t spend a long time waiting around. Their prices are right and the staff is awesome.

Jose A. from La Habra, CA (Source: Yelp)


What makes a dentist stand out from the rest? Having a personality and taking a genuine interest in his patients. Besides all that, Dr. O’Connor is a very accomplished professional with an equally friendly professional staff. Schedule your appointment now, you won’t regret it.

Kimberley B. from La Habra, CA (Source: Yelp)


Dr Patrick O’Connor is the best of the best! He’s so kind, he & his staff make you feel like part of a big family. I’m so grateful I have a dentist I trust.

Tony Magnemi (Source: Google)


Dr. O’Connor is the best!!! Very professional, knowledgeable and friendly. All the most modern equipment, amazing staff and great hours. If you are looking for a great dentist, look no further!!!

Cindia V. from La Puente, CA (Source: Yelp)


A great friend of mine referred me to see Dr. O’Connor. I hadn’t been to the dentist in a while and was feeling nervous about returning. Dr. O’Connor and all of his amazing staff made me feel welcomed, informed, at ease. Every staff member that I encountered (about five!), were incredibly warm and professional. They kindly accommodated me by giving me an early appointment in order for me to be at work on time. Jane was my hygienist was terrific, she made me feel comfortable and walked me through everything that she was doing. In addition, she answered every question that I had. Dr. O’Connor was incredibly nice, cheerful and knowledgeable, I now have a game plan on how to strengthen my oral health. I am so happy that I chose to see Dr. O’Connor!

If anyone is scared to visit or is in search of a dentist, I highly recommend Dr. O’Connor’s office. I guarantee that everyone in his office will be courteous and caring. I am so grateful for the help I received today and you will as well.

Joe B. from Evans, CO (Source: Yelp)


I used to live in La Habra and for many years. Dr. Patrick O’Connor was the most awesome dentist. Due to poor quality dental work done when I was a child Dr. O’Connor had to rebuild a lot of my mouth and his work still is in great shape today.

The quality of his work was more than outstanding and he is a great man when you get to know him he was an athlete and an avid photographer as well as a family man. BEST DENTIST EVER (…)

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


Had a molar crack and then break off.  Called Dr. O’Connor and he got me in first thing in the morning.  He is very supportive and detailed.  My confidence level is always high when I see him.  He does great work and explains everything.  His staff is also stellar.  They work together as a team.  I highly recommend Dr. O’Connor for your dental needs.

Sandie C. from Fullerton, CA (Source: Yelp)


Dr. O’Connor is the best dentist ever! I am terrified of any dentist and he always puts me at ease. He is positive, professional and kind. The most trustworthy dentist there is. I highly recommend him.

All of the hygienists are good but Kim is really terrific!!!


Dr. O'Connor started this practice in 1979 in La Mirada after graduating from USC School of Dentistry. He practiced there for 13 years before moving to it's present location in La Habra. We've been practicing Family Dentistry with an emphasis on today's technology and yesterday's values. We started with PPO plans several years ago and continue to get the best coverage for our patients. We like to think of ourselves as the "non-clinic", one Doctor with one office. Dr. Patrick O'Connor, a native Californian, received his Bachelor of Arts in Biological Science from California State University at Fullerton in 1975. He graduated with a Doctorate of Dental Surgery degree from USC in 1979. He practiced in La Mirada for 13 years then moved his office down the street to it's present location where he has practiced since 1992. Dr. O'Connor believes in conservative, value based dental treatment with the emphasis on integrating the mouth with the rest of the head. Recent research has shown how destructive the lack of a good relationship of the mouth to the musculo-skeletal structures can become with aging. Dr. O'Connor regularly attends continuing education seminars and conferences to stay abreast of the latest techniques and their supporting research. Dr. O'Connor is married and has a son and a daughter. Both his children attended the University of Oregon. They enjoy water skiing, surfing, motorcycles, off-roading and RV camping.
