Our Dentist

Dr. Mohammad Moridnia DDS

or as his patients lovingly call him Dr. Mo

Dr. Mohammad MoridniaWelcome to our family at Sima Family Dental. the top Sima dental care, TX. I am excited to meet and get to know each and every patient that comes through our office. I always knew I wanted to do something in the health care professions. As I explored my options, I gravitated directly towards dentistry. I truly feel blessed to be able to go to work every day and do what I love. In fact, my favorite part about dentistry is being able to form personal relationships with patients and interact with them on a regular basis. I have called Houston my home for the last eleven years. After an early graduation from University of Texas at Austin , I got accepted into dental school in San Antonio, one of the best in the nation, winning awards and participating in numerous volunteer activities.

In my opinion, regardless of what you choose as a profession, you can never stop learning. To keep up to date with the newest technology, products, and ideas, I always commit to attending continuing dental education courses regularly. This ensures I can continue to provide only the highest level of care for my patients.

On a personal note, I also enjoy many things outside of dentistry. I primarily enjoy spending time with my family. I was also a professional soccer player as a teenager and now whenever I get some time I play soccer. I also like swimming and volleyball.

Dr. Jeff Shao

Love Of Orthodontics

Dr. Jeff ShaoThere is nothing like the feeling of changing someone’s life through braces and various orthodontic techniques. The smiles I can create for my patients have such a significant impact on their lives and are truly rewarding to see. As an orthodontist, I feel very blessed and privileged to be part of that positive change.

Orthodontics is not only a science, it’s also an art. I love witnessing how each person comes in with varying degrees of malocclusion, yet each has the same goal: a healthy, beautiful smile. It’s my responsibility to use my skills and knowledge to make that happen, and develop a treatment path that’s right for them. What’s best of all, at least for me, is that I use my knowledge to create smiles for people I care about.

My patients are fascinating individuals, and I love getting to know them on a personal level, building relationships as their treatment progresses. I enjoy hearing their stories and learning about their interests and families. It is an honor to provide care for such wonderful people and to help them attain great oral health and a beautiful smile while we become friends.

Education And Continuing Education

My Doctorate of Dental Surgery and Master of Science degrees were both awarded at the University of Texas Health Science Center at San Antonio. The education I received in these programs was top-notch. The last dental ranking of US News & World Report ranked UTHSCSA as #1 dental school in the nation.

Oral healthcare, and especially orthodontics, is an ever-changing field, with new technologies, materials, and treatment methodologies constantly being developed. It’s essential that I stay on the leading edge of knowledge in order to provide my patients with the best care available, so I attend multiple meetings, conferences, and lectures throughout the year, including those offered by the American Association of Orthodontists and the American Dental Association. I am also a Board-Certified orthodontist by the American Board of Orthodontics.

Personal Life

I was born and raised in Texas, and now call The Woodlands my home, where I live with my lovely wife, who’s from the Houston area. I love going to the movies, traveling the globe when I have the chance, and being an avid foodie. I am also quite adventurous; I enjoy ziplining, swimming in a shark cage, and snorkeling with sea turtles when I’m on vacation.

At home, I’m active in our community. I volunteer with programs that offer free and low-cost dental care to underserved communities. I’ve also been part of the Habitat for Humanity program since 2007.
