Dr. Rafik Riad

Hello, and thank you for taking the time to get to know us.

I am Dr. Rafik Riad, born and raised in Cairo, Egypt. I made the decision to be a dentist when I was 14 years old. I earned my first Doctorate from the prestigious Ain Shams University in Cairo in 2005 when I was 22. After graduating with honors, I practiced the art of dentistry in my hometown for several years and developed a strong passion for the art of dentistry.

As an eager learner and a firm believer in never-ending professional and personal development, in 2008, I became a co-founder of a continuous education institute for dentists, aiming to bring global knowledge and cutting-edge technology in dentistry to doctors in Egypt and Europe. Read more

In 2010, I moved to the USA and decided to continue to pursue my dream and my passion for dentistry. I graduated from Loma Linda University in 2014. I have gained a lot of experience and knowledge since then, and my passion for dentistry and the art of changing people's lives by simply making them smile continues to grow.

Dr. Rakan Alzwaideh, Endodontist

Hello, I am Dr. Rakan Alzwaideh. I graduated from NYU College of Dentistry with a DDS degree in 2016. I then completed a one-year hospital residency at Lutheran Hospital in New York, during which my passion for endodontics was solidified.

Jennifer, Dental Hygienist

Hello, I am Jennifer. I have worked in the field of dentistry for more than 10 years. I earned my dental hygiene degree in 2012 from Fresno City College. I was a dental assistant in General Practice and Endodontics. I also received my bachelor’s degree in Psychology.

Laura, RDAEF2

Registered Dental Assistant

My family and I have been a part of Oak Tree Dental for over 10 years now. My husband and I have two beautiful daughters that love to practice Jiu-Jitsu and visit me at work for their routine cleaning. My career started in 2007 as an assistant, where I found my passion for dentistry with our family dentist. I then moved to Oak Tree Dental in 2012 as a scheduling coordinator and absolutely fell in love with our patients and the community that surrounded the office. After 18 months of working in the front office, I realized how much I missed assisting. In 2021 I completed my RDAEF2 course receiving my license that same year. Now I get to deliver crowns and complete crown preps and fillings. I am diligent in providing excellent patient care and quality restorations while utilizing state-of-the-art technology. I have enjoyed seeing several of our kid patients become teenagers and have developed several friendships with others. The smiles I get from my patients and having such wonderful and fun coworkers keep me coming back to work every day.
