Dr. Youssef is the BEST orthodontist. I got my Inbrace with him less than a month ago and I was already seeing progress within 2 weeks. I drive almost an hour to get there & it’s so worth it. He is very knowledgable, truly an expert, and perfectionist at what he does. Every time I’m in the office, Dr. Youssef takes the time to answer all of my questions and pays very close attention to detail. I can tell he genuinely cares and I already feel so much more confident with my smile. I’m very impressed by his work and have trust that I will leave his office with a beautiful smile!! The office itself is also very welcoming. The staff are friendly, do a wonderful job, and make me feel super comfortable. I know I’m in the best hands here and would highly recommend any one who is excited to get their perfect smile

Dr. Youssef is great in answering all questions and paying full attention to all details. He walks you over the treatment at the beginning, and make sure you are both aligned on the steps that will happen. He is very accommodating and willing to provide you with different options till you are comfortable. He doesn’t shy away from going the extra mile to make sure he earns your trust and satisfaction. I was very impressed and satisfied with the whole experience and the end result exceeded my expectations for sure. Also Crystal his assistant is nothing but a rockstar! most pleasant and experienced orthodontist assistant for sure!

I started my invisalign treatment with Dr. Youssef over a year ago and it was one of the best decisions I’ve ever made. He is not only incredibly knowledgeable and amazing at what he does, but he is so down to earth, humble, and personable. He doesnt treat you like a patient, he treats you like a friend. He made me feel comfortable from the start and I honestly look forward to each of my appointments. The staff is always so nice and pleasant.

The Doctors care not only for your teeth, but they also care about you as a person! They give the best quality of service and I am proud to say that I am apart of the FitSmiles Community! They went above and beyond for me and my family. They took amazing care of us and I know they will take great care of you and your family as well! Again, I would recommend this Facility to not only my family and friends but to those who are looking for outstanding care and results!

He has a lot of options that suits all needs and he goes through every option with his patient Explaining everything in a very simplified way . He has most updated technology like the behind teeth braces which is 100% INVISIBLE!!

I highly recommend FitSmiles Orthodontics! Dr. Youssef is an excellent dentist. He is very thorough, utilizes top of the line equipment/technology like the invisible brackets and wires. He genuinely cares about his patients. Dr. Youssef is excellent at dealing with all sorts of dental needs and the results of his work are fantastic!  Also, the office staff at FitSmiles is extremely friendly and kind (and they don’t make you feel bad about going a little too long in between cleanings :). If you are looking for a new orthodontist, this is the place to go!

Dr. Youssef has been my orthodontist since 2017 and I couldn’t have asked for a more talented/experienced dentist. He will explain every step of the way of your treatment so that you are never confused and fully aware of what is happening. Dr. Youssef will also give you all the options available according to your needs , and he will not cheat you or rip you off because he truly cares about his patients. He would answer all my questions with great detail, and he even simplifies the answers to the individuals understanding level of dentistry. Dr. Youssef will take on a challenge no matter how hard your case is! My teeth shifted after braces and I wanted to straighten them again with braces, but I gave him a specific date that I wanted them off—he took the challenge and my teeth are already straightening.
You would not regret choosing him as your orthodontist!

Dr Youssef is the best orthodontist in SoCal. If you are looking to have the best smile, he is the man for the job. I have seen Dr Youssef for a total of 5 visits for my Inbrace treatment ( invisible braces behind the teeth) and I left with a perfect smile within 9 months . I couldn’t be happier for the results that took a very short time. Dr Youssef is an expert in his field, very knowledgeable and friendly. He took care of every detail in my treatment, listened for every concern I had and was very patient with me.

You will not find a more detail oriented and passionate Orthodontist to help you achieve your perfect smile!!! Dr. Youssef is as excellent as they come. He is honest, conservative in his treatment approach, and goes above and beyond to provide excellent treatment. He offers every variety of treatment from young children treatment to esthetic options for adults and teens of all ages. His staff is highly skilled and the office is beautiful and conveniently located with great parking. Definitely check him out if you’re looking for quality care at an affordable price!

Dr. Youssef is the best in the area. His friendliness with his staff and patients is what sets him apart from other doctors. On every occasion, he takes the time to explain the treatment and answer all my questions without rushing. The patient is the priority to Dr. Youssef, something that other orthodontists seem to forget. I really enjoy coming to his office and getting top notch treatment. He is able to keep up with the innovation and new techniques in orthodontics and is one of the front runners in InBrace. Highly recommend giving Dr. Youssef a try!

Yasmin T. from Gardena, CA (Source: Yelp)


MR. handsome  Dr.Youssef did an amazing job. I am very pleased with my results. Two years with braces didn’t seem long after removing them. Totally worth it. He went above and beyond in correcting every detail in my bite and teeth. Thank you. And also to Lety and the orthodontist staff they are great. Friendly greetings on every visit. Thank you again I appreciate all the work that was done.

Suzan W. from Lake Forest, CA (Source: Yelp)


I went to Dr Youssef according to one of my friends recommendation for my son teeth. I was worried in the beginning because he is so young and might doesn’t have enough experience but actually he did a great job with my son. He made him feel more confident and so happy with his teeth. When I saw this result I decided to start Invisalign with him too. Dr Yousef is so honest and gave us enough time to explain everything to us and so patient. I highly recommend him

Dr Hany Youssef is one of the brightest Orthodontists I know. He has great passion for excellence and providing the latest and best treatment for his patients. As a fellow professional I highly respect him and highly recommend him.

Edwin R. from Long Beach, CA (Source: Yelp)


A few years ago I had braces to correct my smile. I have been wanting to finish the process, because I made my previous orthodontist take the braces wait to soon. I have done several consultations, but coming to fit smiles orthodontics was a really awesome process. From the team there, who know what customer service is all about, to my dentist, Dr. Youseff- Who has a clear understanding of orthodontics, and is one of the best on the field. Their state of the art equipment, really helps you understand and visualize what your teeth will look like after treatment. I am looking forward to my Invisalign trays coming in and starting this new journey. I totally recommend this office!

We (my 3 daughters) have been patients of Dr. Hany Youssef since 2017 and can’t express our satisfaction and happiness with him because of the great job he has done for us. We have a fantastic dental experience. He does his work in a friendly, professional and painless manner. Whenever one of my daughters had a dental issue that needed immediate attention, he handled it in an impressive way. If you are looking for a smart and knowledgeable dentist, then Dr. Youssef is a great match and I highly recommend him.

Karim Y. from Irvine, CA (Source: Yelp)


My experience at fitsmiles orthodontics was amazing. I went from a little boy that had big gaps and an awful smile to no gaps and a great smile. Doctor Hany changed the way i looked completely from bad to amazing. Doctor Ziad also led the way to me looking like this. He is very dedicated and well trained in the field of dentistry. Thanks to Doctor Hany and Doctor Ziad and all the nurses and front desk, They have made me look like another man. The respect and hygiene in the area is excellent. Ever since i walked in i knew that i was gonna be in great hands. Even during this quarantine due to the COVID-19 they have taken lots of caution and safety precautions. If i could give them a 10 Star i would definitely give them. Highly recommended. Thank you very much to everyone there that has given me the confidence to go out and always have a smile on my face.

My kids have been a patient of Dr Youssef for a few years now, Dr Youssef and his wonderful staff Crystal/Brenda to name a few have always treated us like family by their understanding/compassionate ways. My daughter always looks forward to her appointments solely because of her interaction with staff,in her words it feels homely. Dr Youssef is an excellent orthodontics and lives to his name of “Dr FitSmiles” his perfectionist ways has improved both of kids smiles. I have recommended many friends and family to him for he has shown he can be trusted for he values all of his patients like family and provides them with the utmost respect. There are many things I love about this office but if I have to speak on one it would be how great Dr Youssef and his office staff communicates with their patients and always makes sure you leave with an understanding of treatment .

I love this place because of the attention we get every time we come even when at times they are so busy!! My family is been part of this family for over 10 years and is been a bless specially now that both or my boys have braces.

I just had one of the best dental experience ever. This office is really cool and has amazing technology. They scanned my teeth with this camera and I was able to see how my teeth will look at the end. Dr. Youssef is super friendly and I felt the connection right away , he took all the time to explain to me the procedures and his diagnosis and treatment recommendation. I could really trust this guy! Highly recommended

Started my braces with Dr. Youssef in April 2019 and the change is unbelievable. He is the type of person that explains the process from start to finish and is very knowledgeable and honest. The whole team at this office is absolutely amazing they treat you as if you are family. The facility is top notch, and they have state of the art equipment.

Danny S. from Los Angeles, CA (Source: Yelp)


Dr. Youssef is one of the most humble and kind hearted person that I’ve had the pleasure of knowing! He treats his patients like family and opens his office up like his home! In the 6 months of being his patient, my teeth are already much straighter and even whiter than ever! I choose to do Invisalign with him and it’s been such a pleasant experience! He’s even seen me after hours since I work til 6 pm and his flexibility is superb!

Rohini Kopparam (Source: Google)


I’ve had a great experience so far with Dr. Youssef and Invisalign! Over six short months the progress in my tooth alignment is extremely remarkable, as seen in the photo. I have uniquely also been living away from the office over the past six months but even remotely, Dr. Youssef charts my progress through photos and is able to any necessary adjustments when I am back visiting home. Highly recommend for orthodontic procedures and general dental health!

Hosam S. from Irvine, CA (Source: Yelp)


Dr. Hany Youssef is a fantastic orthodontist!!! My daughter, Nora (15), just completed her treatment under the care of Dr. Youssef. She finally had her braces removed after 18-months of outstanding treatment and care by Dr. Youssef… and what an amazing outcome! She is super happy with her new beautiful smile! Throughout the entire treatment, and the monthly check-ups with Dr. Youssef, we were always treated as family… and Dr. Youssef took great care to personally explain every detail along the way, and the progress made at every step, and answered all of our questions in a very professional manner. He is very knowledgeable and passionate about his work – and it clearly shows in the way he explains things and the level of details he provides. Above all, he is very friendly and makes everyone around him very comfortable! He’s truly one of a kind and we’re grateful for his wonderful manners and unmatched professionalism!! I highly recommend Dr. Youssef for anyone seeking orthodontist treatment and a great smile!

Diana G. from Long Beach, CA (Source: Yelp)


If you’re looking into improving your smile and dental health (and even your life!) I ONLY recommend Dr. Youssef! I started my braces elsewhere and I was not happy with how the treatment was going and how they would treat me. (I felt like I was just a number) I’ve had the pleasure of working with Dr. Youssef and would always see his passion for ortho and how he would always strive for perfection in his work. So I made the easy decision of starting over and starting treatment with him and I’m so glad I did. He treats his patients like family and he’s so educational and walks you thru EVERYTHING! I never left the office concerned over what was done or what the next step was. Last year I had my son start treatment as well and it’s been the best experience for him. Thank you so much Dr. Youssef!

I have always wanted straight teeth but because I am a dentist I never wanted to have braces on as a professional adult. I have heard from my friends about this new technique called Inbrace, it is braces from behind the teeth and is 100% invisible. After intense research I found that Dr. Youssef is the master of this technique. I am so excited to get my teeth straight and it is truly 100% invisible

5 stars are less for Fitsmiles and Dr Hany Youssef and his staff. I have started my Invisalign align treatment with Dr Hany. He has been flawless with his treatment and is very knowledgeable Dr from USC. His staff is amazing, very very friendly and organized. The equipment there is top notch with affordable prices for the services provided . In spite of living in Beverly Hills , I travel 80 miles to Fitsmiles just for the services provided by Fitsmiles and Dr Hany Youssef. I just love this place for my teeth. Organized friendly cheap knowledgeable All in one.

Awesome orthodontist! Much respect; he’s a strong advocate for patients and top-notch with patient education. His knowledge and insight bring clarity and confidence to help make smart choices regarding appropriate treatment. Two thumbs up!

Dr. Hany Youssef is the best Orthodontist I’ve ever met. He is extremely knowledgeable and caring. He is always looking for the latest technologies. When I went to his practice it he commanded that I get a Inbrace instead of the regular metal braces, this is a new technology in which the braces are behind the teeth. It has been only for a month and I already could not believe myself with the progress. I have called Dr. Youssef several times to ask questions about my treatment and he never hesitated to take the time to answer my questions and explain everything that’s going on and the plan for what’s next. I would highly recommend him to anyone who is looking for a beautiful smile.

Patrick N. from Rancho Cucamonga, CA (Source: Yelp)


If you are looking for a confident smile, look no further. Dr. Hany is truly one of a kind! The entire office is very clean, professional, and the staff do a great job of being patient and gentle while explaining every step of the procedure. Scheduling an appointment was easy and efficient. I got some work done very quickly and couldn’t be happier with my results. My smile was perfect for my wedding. Thanks again, Dr. Hany!
