They are also a bunch of very attractive ladies that do their jobs well to. Shirani's experience and expertise in the dental field is unmatched in my opinion, my family and I have been going to him for years and have never been left in pain. Over the past 10 yrs I have been to several dentist in the Antioch area, who have done to say the least mediocre work that Der. Shirani has corrected. Not only corrected but never ever throwing the other dentist under the bus. His other absolutely Gorgeous dentist, whom name evades me "sorry" is a tru- BOSS!!! She so sweet and gentle as Shirani, and always a pleasure to see and speak with. The manner in which the team is managed definitely reflects in how they treat us the patients . So thank you Dr.s. I definitely recommend this establishment. Thank all of you for being you. You all are absolutely awesome.

I usually don't leave negative reviews but i was pretty disappointed with the way I was greeted on the phone by the receptionist when I needed to change my appointment. I never cancelled last minute & always wanted to reschedule in hopes of being able to be seen. Completely rude. Just a reminder that the person who's answering the phone is making an impression on future patients. Especially ones like me who were coming to you out of network. Disappointing experience.

I am eternally grateful for everyone here at Dion Health. Everyone from the front office staff;…read more Stephanie and Heather to the Director of Operations; Danielle Farwell. None of this would have been possible if it wasn't for them. What sticks out with this Dental office from the rest is that they're not in this profession to make money they genuinely do this for the patients. They want to make a difference in peoples lives and they will work with you no matter your financial situation. Dr. Saleeb and his dental assistant Alyssia are absolute angels. They worked tirelessly for 8 straight hours, and their care was beyond anything I could've imagined. Dr. Saleeb is not only an amazing Dental Surgeon but he's genuinely a caring person. Throughout this whole process not once have I felt pressured into getting something that I didn't need. The whole procedure was so much easier than I ever anticipated, Dr. Saleeb is so gentle -- I had NO PAIN the day after surgery and no bruising at all. I didn't even need to take any of the Norcos I was prescribed. Dion Health has given me so much more than just a beautiful smile--they've given me the confidence and peace of mind I never thought I would have again.

I went to this office for a consultation and was told I needed to have all of my teeth removed and…read morereplaced with implants and crowns. After the consultation, I paid a $3,000 deposit to schedule the procedure. After thinking carefully about such a major, life-changing treatment, I realized I wasn't comfortable moving forward. I canceled my appointment two days before the scheduled procedure. What shocked me was that the office kept $1,800 of my deposit. I was never asked to sign a financial agreement or cancellation policy explaining that I would lose such a large amount if I canceled. When I asked for an explanation, I didn't feel the situation was handled fairly. I'm sharing my experience so others know to ask detailed questions about deposits, refunds, and cancellation policies before paying any money. If you're considering major dental work, make sure you get every financial policy in writing before making a commitment. This was my personal experience, and I hope it helps others make an informed decision.
