Welcome to Our Practice

A message from Dr. Lena M. Qahwash:

Dear Patient,

I would like to take this opportunity to thank you for your continued trust and confidence in permitting me to care for you and your family's dental needs through the years. It is with mixed emotions that I am announcing my retirement from my practice.

To ensure that my patients continue to receive the best possible care, I have carefully evaluated several candidates who were interested in assuming my practice. I am pleased to inform you that I have selected Dr. Justina Mockunas. 

Dr. Justina is a caring and talented dentist who possesses the highest qualifications and is well skilled in all phases of dentistry. She graduated from Kaunas University of Medicine, College of Dentistry in Lithuania in 2008. 

After years in private practice, she decided to pursue advanced education. She joined the renowned New York University Langone Dental Health Organization, which offers postdoctorate dental residency programs. In 2019, after a two-year residency training, Dr. Justina obtained an Advanced General Dentistry Certification. 

During her years of private practice, Dr. Justina has learned that making others smile from the inside out is what drives her to become a better dentist. Dr. Justina's knowledge, gentle chair-side manner, and positive personality help to decrease her patient's dental anxiety. She enjoys educating her patients about oral health, as she also constantly strives for excellence in dentistry by attending continuing education training courses to better serve her patients. She is committed to providing her patients with personalized care and kindness.

I will be working with Dr. Justina to ensure a smooth transition. As always, my wonderful staff will be there to help you. The office location and telephone number will also remain the same.

I want to thank all of you. Many of you were more than patients, but friends who I looked forward to seeing at each visit. 

Have faith and trust in Dr. Justina Mockunas as she is a gifted dentist. I am very grateful for her assistance in continuing the quality of care that you deserve.
