Meet Dr. Richard Y. Marn

Your anesthesia care will be provided by Dr. Richard Marn, a Board-Certified anesthesiologist and Board-Certified pediatric anesthesiologist with over 15 years of experience.

Dr. Marn was born and raised in Honolulu, Hawaii.  He received his undergraduate degree in Chemistry from Washington University, graduating 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 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.




Dr. Marn’s philosophy is to tailor his anesthetic to the patient, surgeon, and surgery.  Intrinsic side effects of anesthesia are inevitable, particularly post operatively.  But his approach, one that he has taught his residents, of striving for “the right amount of anesthesia at the right time” he trusts will help to prevent complications and minimize anesthetic side effects.  He believes each patient should be treated with compassion, sincerity, and understanding.

Dr. Marn is also a firm believer that strong team-work fosters better outcomes and efficiency.  He will work with a surgeon or dentist, and their team, to create a positive and productive environment.
