I had a wonderful experience at Sigma Dental Clinic. Having not seen a dentist for many (many) years, I was nervous going in but everyone at Sigma is so kind and put me at ease.

I needed four small fillings due to gum recession. Dr. Dashti is gentle and explains what she is going to do before she does it, and there's a TV on the ceiling to entertain you while you're having your procedure! Tyrone is personable and efficient, and the kind gentleman at the front desk is awesome. He obtained a prior authorization from my insurance so I knew what my out of pocket would be beforehand and everything was ready to go when I got there.

My teeth look great! Thanks Sigma team! See you in six months. 😁

Dr. Sepi Dashti provides an outstanding level of dental care. She is highly knowledgeable, professional, thorough, and attentive to her patients’ needs. She takes the time to explain each step of the treatment process clearly and ensures that patients feel comfortable and well informed throughout their visit.

Her attention to detail, clinical expertise, and thoughtful approach to patient care are truly impressive. The entire office reflects the same high standard of professionalism and creates a welcoming and comfortable environment.

I highly recommend Dr. Dashti to anyone seeking a skilled, trustworthy, and dedicated dentist who consistently provides excellent care.

The dentist is very gentle and nice and I have been recommending her around the area. The office manager on the other hand was yelling / arguing with me when I tried to make an appointment for a specific issue. He made us not want to return or recommend. I believe he had mistaken me for another patient and would not even try to understand his mistake when I tried to correct him. Having dental work is already stressful and when the office manager doesn't have clear communication and is using contradictory phrases it makes the experience so much worse and degrades trust.

I had a great experience at the clinic! The team is fantastic, and Dr. Sepi is incredibly gentle and took the time to explain everything to me—something I haven't encountered before. I highly recommend this place to anyone in search of a dentist!

I had my wisdom teeth removed at Sigma Dental recently, and the entire experience was far better than I expected given how nervous I was about the procedure.

I was naturally a bit anxious heading in, but the team made me feel completely comfortable from start to finish. The dentist (Dr Septic Dashti) explained every step of the process beforehand, answered all my questions, and made sure I didn't feel a thing during the procedure. Post-op instructions were clear and easy to follow, making recovery smooth and manageable. Highly recommend Sigma Dental for anyone nervous about dental procedures!
