Long Time Volunteer and Hospital Advisory Board Member Named Honoree of Mount Sinai South Nassau’s 41st Annual Golf Outing

Hospital Cardiology Chair, Oceanside firefighter also to be honored

In recognition of his more than two decades of volunteer service and leadership as a member of Mount Sinai South Nassau’s advisory board, Peter C. Breitstone, a leading insurance industry executive, has been named honoree of the hospital’s 41st Annual Golf Outing to be held Monday, May 12.

Lawrence Kanner, MD, Chair of Mount Sinai South Nassau’s Department of Cardiology, will be the Clinical Honoree of the annual outing, while Kevin Klein, Second Assistant Chief, Oceanside Fire Department, will be presented with the hospital’s Community Service Award.

The largest annual hospital golf fundraiser on Long Island, the outing will be held at four prestigious and challenging golf venues: The Seawane Club, Hewlett Harbor; Rockaway Hunting Club, Lawrence; Rockville Links Club, Rockville Centre; and the famed Red Course at Eisenhower Park in East Meadow.

Net proceeds of this year’s tournament will benefit the expansion of Mount Sinai South Nassau’s comprehensive cardiology program. In collaboration with the world-renowned Mount Sinai Fuster Heart Hospital, Mount Sinai South Nassau provides the latest advances in medical interventions and therapies to treat a wide spectrum of cardiovascular conditions. The Feil Family Pavilion, the hospital’s new four-story patient care pavilion, opening later this year, includes nine new operating rooms which will enable the hospital to perform the most complex of surgical procedures, including open heart surgery in Oceanside, pending New York State Department of Health approval. Advancing life-saving cardiology technology ensures that patients and their families on the South Shore do not always have to travel to the North Shore or into Manhattan to seek care.

“Mount Sinai’s goal is to provide advanced cardiac care right here on the South Shore of Long Island,” said Adhi Sharma, MD, President. “It’s better for patients and their families. The expansion of our cardiovascular services is part of that plan so the residents we serve will have convenient access to world-leading cardiologists and proven life-saving treatments.

“Peter Breistone has been a forceful patient advocate and volunteer board member for more than 20 years, so this honor is well deserved,” said Dr. Sharma. “He has helped us grow from a small community hospital to the regional medical center we are today.”

“Our current cardiac service, which includes our cardiac catheterization lab, is second to none on Long Island and that is due in large part to Dr. Kanner and his team. He is the personification of a physician-leader who is dedicated to his patients and to the hospital,” Dr. Sharma added.

Golf Committee Co-Chair Jeff Greenfield praised the outing’s community service honoree, Chief Klein. “Chief Klein is a first responder’s first responder. He is well respected for his years of dedication to the Oceanside community and to his fellow volunteer firefighters. As an Oceanside chief, he often has responded to accidents and emergencies, whether big or small, involving Oceanside residents who are transported to Mount Sinai South Nassau for the emergency medical care they need. He knows the hospital and our patients. And he has repeatedly demonstrated his commitment to the communities we serve.”



Presently serving as treasurer of Mount Sinai South Nassau’s Community Advisory Board, Mr. Breitstone was appointed to the board in 2003 (when it functioned as the hospital’s Board of Directors). Since then, Mr. Breitstone’s expertise, experience, and comprehensive background in insurance, risk management, and law have been essential to Mount Sinai South Nassau’s long-term strategic expansion into a regional medical center that is the Long Island flagship hospital of the Mount Sinai Health System with an integrated network of specialty medical practices including a free-standing Emergency Department in Long Beach.

Mr. Breitstone leads all facets of his self-built consultancy and insurance brokerage firm, delivering services to Fortune 500 insurance corporations, insurance technology start-ups, key private equity and venture-capital firms, and large health care organizations. He expanded a second-generation insurance agency into a specialty risk and insurance brokerage firm and created one of the first boutique environmental brokerage firms serving global and local businesses.

He has advised on organizational change for companies including Goji, Insureon, Zurich North America, and Aon. A member of the Bar in New York State and the District of Columbia, Mr. Breitstone serves as chair of the Village of Lloyd Harbor’s Harbor Control Commission and a member of the village’s Planning Board. He and his wife, Dianne, live in Lloyd Harbor and they have three children, JB, Jack, and Matthew.

“Peter’s longstanding leadership and commitment to Mount Sinai South Nassau and our board have been invaluable to our mission,” said Anthony Cancellieri, Co-Chair of the hospital’s Advisory Board.

A fellow of the Heart Rhythm Society, Dr. Kanner oversees and directs electrophysiology operations in Mount Sinai South Nassau’s state-of-the-art lab. He treats patients who have a variety of cardiac rhythm disorders and congestive heart failure with medications, pacemakers, defibrillators, and the latest in advanced cardiac ablation techniques.

Since joining Mount Sinai South Nassau’s cardiology staff as Director of Electrophysiology in 2008, Dr. Kanner has been in the forefront of treating heart rhythm disorders with the latest advances in implantable cardio-defibrillator devices and electrophysiology services. He was the first electrophysiologist on Long Island to implant several groundbreaking cardiac devices: the Viva® cardiac resynchronization therapy device with defibrillation (CRT-D) (which continuously adjusts to individual patient needs and preserves each patient’s normal heart rhythms); Incepta® ICD (recognized as the world’s smallest and thinnest Implantable Cardioverter-Defibrillator), and Evia® pacemaker (which incorporates a wireless monitoring system that immediately notifies the patient’s physician if the patient or the pacemaker is experiencing complications).

Chief Klein has served the Oceanside community for more than 32 years and is currently the Second Assistant Chief of the Oceanside Fire Department. A member of the department since January 1993, he previously served as Chief of the Department in 2013, 2017, and 2018 and is the longest-serving Chief in department history. In addition to this volunteer service, Chief Klein is employed as a dispatcher by the North Bellmore Fire District and as the Assistant Clerk of the Hewlett Bay Fire District.

Over the course of his career, he has been awarded four Life Saving Awards, three EMS Unit Citations, and four Engine and Ladder Unit Citations. Chief Klein was awarded the Oceanside Kiwanis Heart of Gold Award in 2017 and was recognized as the Oceanside – Island Park Herald Person of the Year in 2018. In 2021, he was appointed to the New York State Volunteer Firefighter Recruitment and Retention Task Force. Chief Klein’s father, Steven, is a former chief of the Oceanside Fire Department, and his son Christopher is a firefighter in Oceanside. His son Kevin Jr. is a career firefighter with the Horry County, South Carolina, Fire Department. Mr. Klein lives in Oceanside with his wife Marianne, and sons Liam and Frank.

“All of our honorees have one thing in common: their service to the hospital and to our communities,” said Mr. Cancellieri. “We plan to make this the biggest and the best golf outing yet so we can continue to help fund the great work of Mount Sinai South Nassau.”
