Gregory Y. Lakas, D.D.S.

"It is with mixed emotions that I announce that I will be retiring from the practice of dentistry on or about October 1, 2020. I am excited that I will be able to spend more time with my family. My grandchildren are the light of my life. But I leave with profound sadness that I will no longer be seeing my patients/friends."

"I have been practicing dentistry for more than 42 years and have truly enjoyed being a dentist. I have taught at Georgetown Dental School, opened a dental clinic at SOME for the indigent of Washington, DC, I have been in private practice in Potomac, MD and been in my Arlington, VA office since 1981. I truly feel that my office was my home and you, my wonderful patients, are my family."

"I leave the practice in the capable hands of my business partner, Dr. Elizabeth Shaeffer. She, with the help of our associates and hygienists, will continue to treat your dental needs."

"Thank you again for the honor and trust of being your dentist."
