What Our Patients Are Saying

I came to Dr. Tajaddod seeking a second opinion as I didn't want to wear braces as a professional working adult. Dr. Tajaddod provided a creative solution that was perfect for my complicated case and I was able to be treated with aligners. She was able to correct my tipped molar, close all my spaces, and realign my bite! She is very meticulous and I'm very happy with my results. The staff is very friendly and appointments always started on time.

Maria M.

Dr. Tajaddod and her team are amazing! Our son is just finishing his Phase 2 with his braces & his smile looks amazing! Phase 1 was a very involved process, and Dr Tajaddod was able to move my son's overbite & his upper palate into position over time with excellence. I highly recommend Dr Tajaddod! Plus, her positive & caring energy & attitude is wonderful!

Rachel C.

Dr. Merna is a true orthodontic wizard! My 9-year-old son had a severely crooked smile with large gaps in his teeth, but under Dr. Merna's care, his smile has completely transformed. The teeth are now straight and beautifully aligned. Dr. Merna's friendly demeanor and exceptional attention to detail made the experience enjoyable for both my son and myself. I highly recommend Dr. Merna to anyone in need of orthodontic care.

Padma P.

I highly recommend Dr. Tajaddod for kids and adults seeking ortho treatment. She is a brilliant Doctor. Your teeth are in great hands here.

Mary B.

I have a very difficult case to treat. Over the past 3 years, doctor Tajaddod keeps trying and working to give me the best result possible with top notch service in the industry. I'm grateful to receive the treatment here and would highly recommend her if you want to have a perfect smile!

Linwei C.

Dr Tajaddod and her staff are the best! She is very experienced with orthodontic needs of the patients. My son and I have been patients in her practice since the pandemic started in 2020. I just finished my InvisAlign treatment and transitioned to retainers. I get so many compliments about my smile! And my son is soon starting with Phase-2 of his treatment. Everything’s been beyond expectations for both of us. Strongly recommend to patients of every age!

Emre A.

Dr Merna Tajaddod is simply the best orthodontist in Silicon Valley. She and her team are professional, competent, and genuinely nice people. I do highly recommend her office for any orthodontic requirement you may have.


Great service and support over the past couple years on this ortho project. The staff was especially accommodating to my busy schedule and provided quick, but excellent engagement, resulting in a winning smile.

Darren A.

I was referred here for Invisalign treatment. Overall, it has been a very positive experience. The whole staff is very friendly, communicative, and helpful. Dr. Tajaddod is extremely knowledgeable and accommodating. My treatment is complete, and I am super happy with my results. Would recommend this office to anyone!

Chidinma U.

Great experience from beginning to end! My Invisalign treatment was a 2-year process with regular visits to the office (every 2-3 months or so). Every visit was pleasant, quick, and simple. The staff is kind and welcoming. Dr. Tajaddod is great at her job and I am very happy with the results!

Joseph B.

Dr. Tajaddod was a fantastic choice for our daughter. Our daughter really wanted the Invisalign braces, and Dr. Tajaddod managed the entire process for us. Dr. Tajaddod is very personable and cheerful, and the front office staff is helpful and professional. Scheduling appointments was never an issue.

Greta G.

Dr. Merna is as good as any orthodontist can get. She takes a lot of pride in her work and is very passionate and goes above and beyond to solve the most complex ortho issues. I don't believe you can find any other Ortho in Palo alto, menlo park and los altos area that can work a magic like her.
