Doctor Testimonials


“This is one of the best courses I have ever taken as it makes you think out of the box. When you look at the patient, you don’t look at his teeth, but you think about how you can save his life from heart attack, sleep apnea, and cardiac problems. We have learned about the posture of the head and how it affects the beauty of the face and the muscles around it. So Dr.Cortes shows us how to make faces beautiful and to give them beautiful smiles and a beautiful life. So I am recommending this course for all dentists to give a good diagnosis and good treatment for sleep apnea. Dr. Cortes’ explanation was so easy to sort out a lot of questions and her experience gave us confidence to start treating the patients without hesitation.”
– Dr. Ali Qamber, DDS

“I wanted to take the time to thank Dr. Cortes AND her wonderful crew for having hosted us all for this awesome course and for making my first stay and visit in New York such an incredible one. I really enjoyed it a lot and it was an incredible group and ambience and, of course , learning more and more is the icing on the cake.”

– Claire Stagg, DDS MS FAACP


“The difference between this course and other dental sleep appliance courses is that the appliance mRNA can not only treat but also gradually work towards curing the underlying OSA. This is what we all should want for our patient!!!

-Rajiv Nanda, DMD MSD

Craniofacial orthopedics is an area of dentistry that is mostly thought of in the context of orthodontics, but this concept should play a central role in treatment planning in any restorative practice, which does anything more complicated than one tooth dentistry.

Using the concepts formalized by G. David Singh, D.D.Sc, Ph.D., BDS, DMD, Dr. Martha Cortes DDS is a gifted leader who has made a commitment to integrate this treatment concept into every day dentistry in her New York City practice. She has been a great help to me as a mentor. If you do any dental sleep medicine in your practice, any major restorative treatment, or if you are an orthodontist you owe it to yourself to carefully investigate this rapidly growing branch of dentistry. It will improve your competence as a dentist; it will improve the quality of the care that you deliver to your patients. It will give you a dramatically increased sense of satisfaction from your profession. It has revolutionized my practice and I believe it will do the same for yours.

The DNA appliance, as developed and patented by G. David Singh, D.D.Sc, Ph.D., BDS, DMD, is an exciting new tool that I believe will eventually become part of the standard of care for dentistry. Its use in craniofacial orthopedics, conventional orthodontics, general and restorative dentistry, and dental sleep medicine has been well established and documented in the literature. I urge you to become educated by Dr.Martha Cortes and Dr. G. D Singh in New York. They make a dynamite teaching team, and offer the ultimate fast-track approach to integrating this exciting new technology into your practice. It has revolutionized my practice and I believe it will do the same for yours.
