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.

Since…read morethen I have been trying to be seen but with my work schedule & commuting 3 hours a day it's been a challenge. 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.

    this place is horrific and I wouldn't recommend anyone here anymore. They told my mom she could get…read moreteeth pulled being on blood thinners up until 20 mins before she was scheduled and that was a lie per the oral surgeon there that day. Then they want to overcharge for a procedure for my dad and claim it wasn't covered from the insurance when our insurance told us they paid everything. Now saying they'll throw us into collections and we are highly uninformed of how medical billing works (moms a medical accountant and I'm an medical assistant we are not uniformed) will never ever EVER tell people back home to call them and will fight them every step of the way. Send us to the fake collections hunny...its a medical bill ;)

    I became a patient in 2015 when I moved to Antioch. At the time the practice was owned by a husband…read moreand wife team. My dentist was Kristen, the wife. She did extensive dental work on me. She told me that all of the previous dental work performed on me over the many years prior by every dentist I have ever had was failing and needed to be re-done. She refilled every cavity and replaced every crown! Later I discovered that not only was much of it was unnecessary but what she did was done was done incorrectly. I last saw Kristen in early 2020, before the pandemic. I returned to the practice after the pandemic in 2022 to find that Kristen was no longer there and her now ex-husband was the sole dentist. My X-rays revealed that much of the work Kristen had done in my mouth was failing and he said it had to be done. I was told that even though the work was done in that office, he was not going to honor any work Kristen had done. The treatment plan he came up with was going to cost me well over $5000. I called my insurance company and they suggested I get another opinion. They told me if I decided to stay with Simpkins Family Dental, I could have my file sent to mediation because most of the work in question was performed within 3 years and should have been corrected by Simpkins. I had the second opinion and yes, Kristen did do sloppy work. I became established under another dentist who was professional and trustworthy. He monitors the subpar work closely. I have since had to have one tooth pulled that Kristen "re-capped". I feel that this practice is predatory and willfully drains insurance coverage. They will not stand by their work. Beware.... Stay away!!!
