Meet Our Doctors

Donna R. Williams, DDS

“We are all connected,” is one of Dr. Williams’ views on life and dentistry. Dr. Williams’ journey over the years, meeting different people, living in different cultures, with the work as a holistic dentist, has developed her understanding as to the many commonalities and ties we have towards one another. Her undergraduate education was at Howard University in Washington, DC. Subsequently, she received her Doctor in Dental Surgery Degree from the first dental school in the world, University of Maryland in 1990.

Dental school was where you learn the basic skills to become a dentist, however, outside of dental school is where her world had been able to expand even more. Growing up, Dr. Williams lived for some of her formative years in Tanzania, East Africa. She was also an exchange student living in Oaxaca, Mexico. Dr. Williams has lived and travelled throughout the Caribbean, West and South Africa, and Europe. She opened her first dental office in Charlotte Amalie, U.S. Virgin Islands, while also working in St. Croix and on the island of Anguilla. In the Caribbean is where she was able to hone her dental skills as a practitioner and learn how to run a dental office.

After leaving the Virgin Islands, Dr. Williams moved to Harlem, NY in 1994, where she worked as a dentist at Harlem Dowling Foster Care Agency, and shortly afterwards opened a solo practice on 125th Street and St. Nicholas Avenues – Morningside Dental Care. The perception of the quality of dental care in Harlem was less than stellar, so she has been determined to change the perception. Morningside Dental Care is one of the finest dental clinics in all of New York City!

They specialize in offering the most up-to-date treatment available. Dr. Williams was one of the first dentists in New York City to offer LANAP (Laser Assisted New Attachment Procedure). This technique is the only FDA approved treatment to help treat gum disease using lasers. This type of treatment has worked wonders for so many patients to save teeth that otherwise would have been extracted. Her office is the only office above 79th Street in Manhattan to have the state of the art CEREC machine, which is a computer and milling machine used to create all porcelain crowns and bridges right in the office. She is certified by The Dental Organization for Conscious Sedation (DOCS) which has enabled her to treat patients who experience dental fear and anxiety they developed from childhood.

In 2003, Dr. Williams obtained a Fellowship in Natural Dentistry (FIND) from the institute of Natural Dentistry, where she learned about the interconnectivity between the mouth and the rest of the body. Problems in the mouth, often generate health issues elsewhere in the body, and vice versa. She is responsible for petitioning Governor Cuomo to recognize February as Gum Disease Awareness Month in the State of New York in 2014. Education is a continuous process, and providing the most current information in oral health care to her patients is her priority, so Dr. Williams recently finished a mini-residency in Airway, TMJ and Sleep Apnea with NYU, because it is so prevalent and can have severe and debilitating health consequences.

Dr. Williams is on the board of directors of Adventures in Health, Education, and Agricultural Development, Inc. (AHEAD, Inc.)

She has a teenage son, Sadiki Emmanuel, and is very happily married to Apolinary “Yonga” Ngirwa. She is passionate about bringing people together, bridge different cultures, and showing how the body is interconnected (the organs and systems to each other); how we are related to each other as human beings on Earth; truly, from the smallest tiny atom, to the universe as a whole.

Raymond Swainson, DDS

Dr. Swainson’s passion for dentistry began when he was 11 years old and would spend summers in Bermuda at his uncle’s dental practice. From those experiences, he fell in love with dentistry. Today, he is a highly qualified dentist that takes extreme pride in providing his patients with the best treatments available. He received his DDS Degree from UCSF in 2000 and acquired 4 years of residential experience in oral and maxillofacial surgery in New York.

Dr. Swainson has a verified history of applying his dental expertise in other countries such as Africa and Bermuda, which has expanded his professional foundation and added to his unique skills and credentials.

Waleed Ben Elchmai, DMD

Dr. Elchmai’s family is originally from Lebanon, but he was born in Queens, NY and has lived here his whole life. Dr. Elchmai has been practicing for 12 years and has worked in several practices in Manhattan and New Jersey through the years. Dr. Elchmai’s undergraduate education was at NJ Dental School now called Rutgers School of Dental Medicine, and his residency was at Hackensack University Medical Center. Dr. Elchmai enjoys all aspects of dentistry and cosmetics, but he really enjoys CEREC restorations.

He is a general dentist and does everything from fillings to crowns and bridges, surgery extractions, root canal, orthodontics or tooth movement, and alignment with Invisalign, dentures and partial dentures, implant restorations, and cosmetic cases. He chose dentistry because it is medical and artistic, which are two things that have always interested him.

Dr. Elchmai feels a great sense of accomplishment when he completes a procedure. He says, “It is very gratifying to complete work that I stand behind and I am proud of and also very nice to feel that I have helped someone be able to function or look better!” When Dr. Elchmai is not at work he enjoys traveling and trying new foods!

Erez Cohen, DDS

Dr. Erez Cohen was born and raised in Brooklyn. Dr. Cohen is continuously educating himself on LANAP. Dr. Cohen joined Morningside Dental Care in 2020. Dr. Cohen’s favorite thing about working in dentistry is improving people’s health and smile. 

When Dr. Cohen is not at the office, he enjoys singing, song writing, and snowboarding whenever possible.
