Dr. Jessica Marn

Dr. Marn has been practicing pediatric dentistry in New York since 2003. She taught residents at three different NYC hospitals for more than ten years prior to opening her second practice in Midtown Manhattan. Dr. Marn has been commended as a “Top Dentist” by the Consumer Research Council of America since 2008. In 2021, the Downtown practice won “The Best Pediatric Dental Practice in Manhattan.”

While earning her Doctorate of Dental Surgery at New York University School of Dentistry, Dr. Marn found her calling and passion for treating children, as well as special needs patients, when she provided dentistry and oral care advocacy for the Special Olympics and Episcopal Social Service in NYC. She then began her pediatric dental residency training at St. Barnabas Hospital (Bronx, NY), nationally recognized as one of the most arduous programs in the country. Upon completion, she earned her board certification in pediatric dentistry and opened her first dental practice on Mott Street (Manhattan, NY), a special place in her heart where she spent much of her childhood visiting her grandmother, cousins, and friends.

Patients come to establish a dental home, get their first checkup, conduct a routine visit, and, if necessary, receive more advanced pediatric dental care and procedures. Because Dr. Marn performed more than 4,000 cases requiring nitrous oxide, intravenous sedation, or general anesthesia, she has developed a unique clinical expertise that few of her colleagues possess.

Dr. Marn is passionate about sharing the benefits of pediatric dental care with her community. Since her training at St. Barnabas, she served on the Early Head Start Health Advisory Committee for more than eight years and partnered with Colgate, Oral B, Crest, and Henry Schein to bring dental education and awareness to Head Start communities. In 2021, Dr. Marn has joined Room to Grow family to help educate her medical colleagues as well as the families in the organization about the importance of good oral health. In 2022, she has joined the Neverrthrist family to bring clean and living water to unreached communities worldwide.  

In 2020, she founded “The Learning Elephant “and authored her first book, “Charlotte wants to be a Pediatric Dentist.” In 2021, Dr. Marn completed Duke University Integrative Health Coaching Training Program because she believes in the overall health and wellness of each of her patients. 

When not practicing dentistry, Dr. Marn enjoys learning, reading, spending time with her family and friends, volunteering for charities, and is working on writing more children’s books.

Dr. Richard Marn

Dr. Marn was born and raised in Honolulu, Hawaii. He received his undergraduate degree in Chemistry from Washington University, graduated magna cum laude, and earned his medical degree from the John A. Burns School of Medicine at the University of Hawaii. After his surgery internship at the University of Colorado Health Sciences Center, he completed an anesthesiology residency at New York University Medical Center and Bellevue Hospital in 2004. He subsequently accomplished a one-year pediatric anesthesiology fellowship at the prestigious Johns Hopkins Hospital in 2005, which at the time was ranked the top hospital in the nation.

Dr. Marn then began working at Mt. Sinai Hospital. As an assistant professor in the division of pediatric anesthesiology at Mt. Sinai Hospital, he has helped train hundreds of residents during which time he was awarded Teacher of the Year in 2008.

As a full-time faculty member for over 10+ years at Mt Sinai, Dr. Marn performed over 11,000 anesthetics (41% pediatric cases, 59% adult cases) for a diverse array of surgeries and procedures. He has worked extensively with multiple nationally-recognized pediatric and adult surgeons and specialists in plastic surgery, general surgery, dental surgery, urology, neurosurgery, liver transplant surgery, and gastroenterology. He has safely performed anesthetics on patients as small as 3 pounds to as large as 360 pounds, and as young as 12 hours old to as old as 94 years old.

During his last couple of years at Mt. Sinai, Dr. Marn co-founded the Division of Radiologic Anesthesiology and served as its first Chief of Radiologic Anesthesiology. He helped grow the Department of Anesthesiology’s role in the Radiology Department and the Hospital itself and created a core group of designated anesthesiologists specializing in radiologic procedures. Dr. Marn improved the way anesthesia was delivered for such radiologic procedures as TIPS, angioplasties, and pediatric and adult neuro-interventional intravascular embolizations. During his leadership of the Division of Radiologic Anesthesiology, the number of anesthesia procedures more than doubled from 110 cases/month to over 230 cases/month. Dr. Marn is very proud of being able to help so many patients during his tenure at Mt. Sinai while also strengthening his department.

In 2016 Dr. Marn departed Mt. Sinai to focus exclusively on private practice and office-based anesthesiology. He remains an active member of the American Society of Anesthesiology, Society of Pediatric Anesthesia, New York State Society of Anesthesiologists, International Anesthesia Research Society, and the Society of Ambulatory Anesthesia. He is double Board-Certified in Anesthesiology and Pediatric Anesthesiology via the American Board of Anesthesiology.
