Dr. Andrei Mihailescu

Dr. Andrei Mihailescu has devoted himself to the treatment of the geriatric population of the greater Portland area since 2005.  It has been his passion to bring the best dental care possible to the seniors—many of whom cannot afford to pay regular fees.  Others are not able to access the necessary care due to their physical impairments or medical conditions. He is enthusiastic about PRIME Geriatric Dental Care because it allows his patients to receive quality dental treatment at more affordable rates.

Dr. Andrei studied at the Portland State University graduating with Honors prior to earning his Doctor of Dental Medicine degree from the Oregon Health and Science University in 2004.  Strongly committed to understanding the latest advancements in dental technology, he regularly attends important seminars and courses. In turn, his staff remains fully informed about the most current techniques available, ensuring that every PRIME Geriatric patient receives superior service for a healthy, functional and beautiful smile.

Main focus of Dr. Andrei is an honest and straightforward approach to each individual patient’s needs and requests. Together with compassionate care and uncompromising quality it has helped him build an outstanding reputation within the local senior community as well as dental profession.

When he is not taking care of his loyal patients Dr. Andrei devotes nearly all of his time to his family.  Together with his wife of twelve years and their three daughters he enjoys all of what Northwest nature has to offer.  Hiking, bicycle riding, camping, horseback riding, berry picking and natural and healthy living in general has been very adventurous and enjoyable for this active family.  When at home—given Oregon weather— the Mihailescu family can usually be found hosting friends and family, participating in a family devotional, reading, or perfecting their new soap recipe.


Dr. Tony Bassili



Dr Bassili's passion for Dentistry started when he was young. "At age ten, I broke my front teeth playing soccer. After several appointments, my dentist restored my front teeth."  Getting his smile back had such a big impact on his self-confidence that this experience led him to his passion for dentistry and it helps him to fully understand what our patients go through.  "Helping people to achieve and maintain excellent dental health gives me the most satisfaction from my profession.  In particular, I enjoy seeing the satisfied smiles of patients when a difficult procedure turns out fabulous!  As a team we pride ourselves in being able to offer our patients the highest quality care.  We are dedicated to communication, availability and the highest quality of Endodontics and Implant treatments.  We use the latest technology in very complex cases".

Dr Bassili graduated from Portland State University and later from OHSU School of Dentistry with a D.M.D. He also received his Endodontic Certificate from the University of Washington School of Dentistry.  Dr Bassili is a member of the American Academy of Implant Dentistry and the American Dental Association.  His awards have included the American Academy of Oral and Maxillofacial Pathology Award.

Dr. Bassili is a joy to have in the office. He is friendly, compassionate, and funny!

A delighted family man, Dr. Bassili relaxes by spending time with his wife Joelle, son Gabriel and daughter Dia.
