I've had dental implants done here, as well as deep cleanings in the past, and every experience has been positive. Dr. Lee is extremely knowledgeable, professional, and genuinely caring. He always takes the time to explain procedures clearly and makes sure I'm comfortable, which I really appreciate--especially with more involved treatments like implants. The office staff are also wonderful--friendly, helpful, and well organized. The whole office has a calm, welcoming atmosphere that makes dental visits much less stressful. Highly recommend Dr. Joseph Lee and Diamond Creek Dental to anyone looking for long-term, trustworthy dental care.

Recently, one of my implant teeth became swollen, and they were able to schedule me right away--even offering a same-day appointment before they closed.

The front desk staff is also very friendly and welcoming. I've recommended many friends and clients to this clinic, and everyone has had excellent experiences!

I explained to the staff that she might need to be seen sooner. Marisol was amazing at informing me of when a cancellation occurred and squeezed us in. The staff were not only extremely professional and knowledgeable but super nice. My little one was apprehensive, but Dr. Chung's expertise with kids proved to be effective. His patience and care put her at ease even through some rather difficult procedures. In the consult, Dr. Chung takes time to explain everything, including options. Let's us know what is necessary, what could happen and what is best case scenario. He puts into consideration the comfort of the patient as well. I'm a widow, only parent here, and I was completely confident that Dr. Chung would provide the best top notch care, and not have to worry about unnecessary treatments. Everything was explained clearly. My kid was very happy after and she did not even know that she got shots....yes, he's THAT good. Happy patient-happy parent!!!!

I've known my dentist, Dr. Sanjay Doshi, for nearly 30 years, as he was my mom's dentist for over…read more25 years and he's been my dentist for the past couple of years. In May of 2025, I received a diagnosis of a highly aggressive, highly metastatic head & neck cancer, of the tonsil, over nine lymph nodes and base of tongue. This type of oropharyngeal cancer threw me into a club that no one should ever be a part of. I was told that without immediate, intensive radiation and chemo (requiring extensive other treatment radiation dentistry), it was terminal. I was given weeks to months. The condition was serious. And time wasn't on my side. After being assessed by my oncology team, I was informed I required the highest level of radiation a patient could be given (70), all the way around my neck, and that I would potentially have dental decay, lose some or all of my teeth have jaw bone decay or even jaw death. My physicians and specialists, including Dr. Doshi, were surprised about my diagnosis. But Dr. Doshi was always confident, from the very start, that I'd get through this, though time was not on my side. He gave me hope from the very start that I would not only survive, but that I would come through this on the other side, and thrive. Thankfully, he was right. Dr. Doshi immediately took me under his dental care, for radiation dentistry, immediately contacted my radiation oncologist, coordinated with him, and began to prep me for radiation (radiation of this nature should never begin until all dental decay and pending dental issues have been addressed). This involved a great deal of work. I never felt overwhelmed about the dentistry, as Doshi took care to keep me safe while working at warp speed to expedite my dental care needs, so that I could quickly begin my treatments. In one month, Dr Doshi did a year's worth of dental work, and he instantly became the a key figure in my cancer care team. Or as I call them, my dream team. He handled my imaging, testing, exams, x-rays, 3 necessary root canals, he had necessary custom fitted, upper and lower radiation guards made (to protect my teeth and gums from radiation during radiation), and a custom fitted, upper and lower fluoride trays, for my daily care, post radiation and chemo. He worked with precision and speed, to ensure I went into my cancer treatments healthy and strong. I went into my treatments with no dental issues or oral infections. It was a brutal cancer treatment. Only someone who's been through this level and type of treatment can truly know how brutal, but I made it through. Thankfully, I am in remission. With a less than 5% chance of recurrence. Radiation to the neck and head can seriously compromise one's dental health, in the short term and long term, so radiation dentistry is necessary before and indefinitely after such an intensive cancer treatment. So I will continue to see Dr. Doshi, moving forward, for closer care - involving more frequent cleanings, more frequent dental exams, and laser gum therapy - to minimize the chances of greater dental damage down the line. He's gone above and beyond in ensuring my dental health is tended to so that my quality of life can be improved upon and hopefully maintained for the remainder of my years. And simultaneously, Thanks to Dr. Doshi, 7 months after cancer treatment ended, I've not lost a single tooth, while other patients reported loss of many or all teeth. I hope to spare my teeth for the long run.

I had been going to Dr Doshi for a long while, and I even referred co-workers and family to him. In…read more2022 I went to Dr. Doshi for some regular dental maintenance and wanted to get Invisalign. In Dr Doshi office I had the 3D scan twice, and never received them. However, in November 2022 my insurance mailed me a check for $5,500 (not exact amount by over that). I text Dr Doshi directly to inform, and he stated that would cover Invisalign. I did not have dental work that cost of $5,500. Here we are 2026 no Invisalign, and I have been ghosted by Dr. Doshi. I have reached out to my insurance to look further into this matter.

As a dentist myself, I chose Dr. Chae to do my dental work because i've been following him for…read moreyears on Instagram and have seen that he does exceptional dental work and diagnosing. Couldn't be happier. I had to have a couple fillings redone that that were acceptable, but not the best. He took pictures along the way to show me the before and afters and I can attest that he takes pride in his work. He's a perfectionist, which means he may diagnose a few more fillings than your average dentist, but as a dentist myself, I would agree that all the fillings diagnose were valid and needed to be done (even if it was a small problem) and the result was something much better after. I'll be back for any other dental work.

Both Dr. Chae and the hygienist were incredibly gentle yet thorough, ensuring every bit of plaque was removed while keeping me comfortable. My teeth have never felt so clean :) Then for my next appointment came the cavity fillings, which I had been a bit nervous for. But Dr. Chae and the hygienist made the entire process seamless and stress-free. They explained every step clearly and ensured I was fully informed about what they were doing. He even took the time to show me all the before and after photos of my teeth throughout the process...I love photos so it was so satisfying to see my own teeth's progress with each appointment and procedure. That level of transparency made me feel so at ease and confident in their care. What I really appreciated was the efficiency of the whole process. I never felt rushed, yet everything was done in a timely manner. Dr. Chae and the team are true professionals who clearly value both quality and respect for their patients' time. Also shout out to the front desk staff for their efficiency and transparency with scheduling and pricing. If you're looking for a dentist who combines exceptional skill, thoroughness, and an honest, caring approach, then you'll love this place!

I visited a PPO dentist, then traveled back to China and saw a dentist there, and also consulted a Korean dentist -- three additional dentists in total, all to verify whether I truly had five cavities.

It has been a long time since I walked out of this dentist's office, and I have not had a single tooth filled, because not one of the three dentists I consulted has told me I need one.

100% RECOMMEND I've…read morebeen sitting on writing a review on Dr. Chen and Skyline dental since forever but I'm finally taking the time! I became a new patient a little over a year ago and I was lucky to find Skyline Dental was in network with my Healthnet PPO dental insurance. I was beginning to tire of my old family dentist (he's literally old and had outdated everything) whom I went to because my parents had been going to him for YEARS but he neglected my teeth and would rather partake in pointless conversation with dental tools in hand! (His name is Dr. Eugene Sekiguchi in Monterey Park if you're wondering) The check-in staff is extremely friendly and patient-something that is a rarity as I've seen many other places with horrible reviews only because the front clerks were jerks. Here, it is nothing like that! Wendy (I believe her name is) gave me a clear price breakdown for everything EVEN IF I CHOSE NOT TO ACCEPT SERVICES. She also gave me a chance to choose which services I'd like to be done and ONLY charged me for those services I approved to be performed (kind of like when you take your car in for service). The dental assistants are also very friendly, efficient, personable, and knowledgeable. On my first visit, they gave me a full check-up and consultation on the health status of my teeth-something my previous dentist kept me COMPLETELY IN THE DARK ABOUT. That was how I found out I had 5 cavities (which explains my minor tooth aches) as well as SEVERE tooth damage due to grinding my teeth at night (because stress). I was under the impression my teeth were 100% healthy due to previous dentist. When Dr. Chen took clear pictures of my teeth for records he took the time to show me that they were really worn down and that I needed to take preventative measures before it gets worse. He also took the time to show me clear x-rays of my cavities, explaining to me exactly what we were looking at. He also talked to me about getting braces should I choose to get them in the future. I have pretty naturally straight teeth IMO and he never made me feel ashamed of my choice not to get braces. These are things I would've never known had I kept going to my old dentist. Harvey, you seriously saved my teeth! On my second visit, I got the first 2 cavities on my bottom jaw taken care of. Mind you, this would be my first time ever getting real nitty gritty work done. I was a little late to this appointment but I called in advance and they still took me! Dr. Chen gave me a little extra to numb the area since it was my first time which was super cool of him. I was drooling like a baby after but my first time experience was a breeze! On my third visit, I got the remaining 3 cavities removed and filled on the top jaw and I literally wanted to fall asleep in the chair. I was very comfortable with their work and felt relaxed and not so anxious as the first time (also had to factor in that I work at 7am and my appointment was after work at 3:30pm). Literally left feeling like a new human after! Unfortunately, I am moving soon and had a change in dental insurance since I got married so I may no longer be coming to Skyline dental (due to the distance it will be from new home) but I would definitely 100% recommend them if they are in network with your insurance!
