Ivan Valcarenghi, DDS, FWCM, FAGD, ABDSM

Dr. Ivan has been in practice over 30 years with an emphasis on cosmetic and rehabilitation dentistry in a multi-specialty group practice in Elmhurst, Illinois. Patients needing complex, comprehensive or multi-disciplinary rehabilitation dentistry, or the advanced skills and cosmetic experience of a cosmetic dentist would benefit from his training. With over 4000 hours of continuing education, Dr. Ivan is committed to life-long learning. He is a certified Toastmaster and professional speaker, has spoken publicly and professionally often and has written numerous articles for professional and lay journals and newspapers. He has also contributed on local radio and T.V. regarding a variety of clinical and practice management topics. He is a graduate of several practice management programs, and has obtained education in business as well as training in marketing and communication.

Dr. Ivan was recently awarded a Fellowship in the Academy of General Dentistry, named one of DCA’s Top 100 Doctors for 2019, and is now a Board Certified Diplomate for the American Board of Dental Sleep Medicine (ABDSM). The ABDSM is the board for the leading national organization for dentists who treat snoring and obstructive sleep apnea with oral appliance therapy. Earning Diplomate status from the ABDSM is a unique honor that recognizes special competency in dental sleep medicine.

While he has a passion for dentistry and often “photoshoots”  his “Smile Makeover” patients, family comes first, and he enjoys celebrating his daughters’ many achievements after graduating Vanderbilt University in Nashville, TN. He is currently serving in his sixth year on Vanderbilt’s Parent & Teacher board. In his spare time, Dr. Ivan has recently discovered K1 racing and the incredibly challenging, yet relaxing, hobby of golf – he regularly shoots in the low to mid 80’s!

One particular area of focus and research for Dr. Valcarenghi is in sleep disorders. He has spoken to professionals and the public understanding the underlying physiology of sleep disorders, an area of growing incidence and sophistication of treatment for patients.

Dr. Valcarenghi obtained his Masters degree (MPH) in Public Health from Loma Linda University Medical Center in California doing research in pulmonary in exercise physiology, nutrition and preventive medicine. The physiology of respiration is of particular interest as it relates to the upper airways in concert with the lower airways and how poor physiology of sleep results in system diseases not to mention neurologic deficits as well as obesity which often exacerbates the underlying sleep disorder.

As one of the principles of the North State Sleep Lab, he has a veritable wealth of experience in Sleep Disordered Breathing or SDB.

We are very happy to add Dr. Valcarenghi’s wealth of knowledge and experience to Radiante’ as a consulting physician.
