I've been a long time patient of Dr Barsoum, and I can honestly say the experience has been…read moreconsistently top-tier. From routine cleanings to more detailed procedures, he's always thorough, patient, and genuinely invested in your long term dental health. What really sets the Upland office for success is the team. I am sure the same standard carries through the entire practice locations. From the front desk always welcoming and efficient (no chaotic waiting room energy) everything runs like a well-orchestrated operation. Dr Barsoum takes the time to explain options clearly, never rushes decisions, and makes you feel comfortable, even if you're not exactly excited about being in a dental chair. The office is clean, modern, and runs on schedule (which I deeply respect). If you are looking for a dentist who combines skill, professionalism and genuinely caring team, this is the place. After years as a patient, I wouldn't trust my sole anywhere else!

I am extremely disappointed with the care I received at Barosum Dental in Upland. My experience…read moreleft me feeling unheard, misdiagnosed, and ultimately traumatized. While I was out of town on July 12, 2026, I developed severe pain on the lower right side of my mouth. As soon as I returned, I scheduled an emergency appointment for July 15. I also had a previously scheduled deep cleaning appointment for July 16. During my emergency visit, the female dentist appeared to minimize my concerns. Instead of focusing on the area where I was experiencing pain, she asked whether I had seen an endodontist for a referral from a year earlier and questioned a shadow in my gums that had existed for over 30 years on the opposite side of my mouth. I requested X-rays, and a 360-degree scan was performed. After reviewing the images, she told me everything looked fine, that I had no cavities, gave me Sensodyne toothpaste for tooth sensitivity, and said I was cleared to proceed with my deep cleaning the following day. Later that same day, the office coordinator called and told me they wanted me to see the endodontist before my cleaning. I went to the appointment, and within five minutes the endodontist identified a cavity. My primary dentist confirmed the finding and recommended that my wisdom tooth be extracted. I was extremely upset that my condition had been missed during my emergency visit. I asked to speak with the female dentist who had evaluated me, but she was unavailable. I scheduled the extraction for July 17, 2026. Because I had previously had a successful experience using nitrous oxide during another tooth extraction, I requested it again to help manage my anxiety. I was numbed for the procedure and was told I was receiving nitrous oxide, but I never felt its effects. I noticed the dental assistant was on the phone for much of the procedure, and it appeared that no one ensured the nasal cannula was properly positioned. I informed both the oral surgeon and the assistant that I did not feel like I was receiving the nitrous oxide, but my concerns were dismissed. I remained anxious throughout the procedure, and the extraction was ultimately unsuccessful. I left the office emotional, traumatized, and deeply disappointed. This was the worst dental experience I have ever had. As healthcare providers, listening to patients is essential. I repeatedly expressed my concerns and felt they were ignored every step of the way. I will not be returning to this office. I also plan to verify that my insurance was not billed for procedures that were not completed, including the deep cleaning and the unsuccessful tooth extraction. I hope this review encourages the office to improve communication, patient care, and attention to patient concerns so that others do not have a similar experience.

You can tell they genuinely care about their patients and go above and beyond to provide top-notch care. The office is clean, modern, and runs efficiently, which makes the entire experience smooth and stress-free. If you're looking for a dental office with outstanding customer service and a team that truly prioritizes patient care, Alta Dental is the place to go.

Stressful & annoying experience just trying to schedule a free consultation. I was asked to provide…read moreX-rays from my previous dentist, which I did, but then received multiple follow-up calls asking for access to the X-rays, treatment recommendations, pricing, and paperwork from other dental offices. What frustrated me most was being repeatedly questioned even after I explained I didn't have the information. For a consultation, it felt excessive and made the experience stressful before I had even stepped into their office. I ended up going to Barsoum dental office in Chino where the consultation was quick, easy, and they even took complimentary X-rays. The difference in the new patient experience was night and day.

The…read moreinitial care involved a consultation, including x-rays, health record and an oral examination by Dr. Reza. Dr. Reza and his staff were the absolute best. From the time I entered the office everyone was professional, courteous and very welcoming. The front desk is very helpful, organized and friendly. The dental assistants and technicians were outstanding, as well. My name was even listed on the board of the office to welcome me to their practice. Their waiting room is clean and videos are very educational, too. Dr Reza reviewed my x-rays and suggested treatment(s). Everything was completely on board and I felt no pressure regarding his suggestions. The follow-up visit involved repairing (3) of my existing resin tooth fillings (which I already knew were an issue) which has now been completed and I can't be any happier with the outcome of my experience. The only suggestion that I have is that additional signing for the (2) entrances at the back of the building from the parking lot would be helpful. If you are looking for a dental practice in the Rancho Cucamonga area, I strongly suggest that you give Dr. Reza and his team consideration. Looking forward to my 6 month teeth cleaning visit. Dr. Reza and his team are A1.

When I asked the front desk clerk whether patients regularly consumed them in the waiting room she confirmed that, yes they do. When asked whether the waiting room was regularly cleaned to assess how much of a risk my child was in sitting in the chairs, she said they clean once daily. The staff did not seem concerned about the risk to my child. They also did not seem educated in preventing allergic reactions for future patients. The clinic was clean and the staff were polite albeit uneducated in food allergies. Those with a tree nut allergy be warned.
