About Us

Since 1980, the East End Financial Group, Inc. (EEFG) has provided expert comprehensive financial planning, investment advisory, insurance, pension administration, estate and retirement planning services for small businesses and individuals.

EEFG is a Registered Investment Advisor with the Securities and Exchange Commission, and offers qualified investors multiple investment platforms.

As an independent, employee-owned company our only allegiance is to our clients. This important distinction enables us to remain truly objective, and work solely in the best interests of our clients as we develop and manage customized planning solutions specifically designed to meet your individual goals, needs and aspirations.

As a result, we are able to take the time to deeply understand the needs and concerns of our clients, build strong personal relationships and offer an unparalleled level of service, accessibility and responsiveness.

Perhaps most importantly, after over three decades of success, East End Financial Group remains a truly local company. We are staffed by local employees who understand and appreciate both the challenges and opportunities unique to the East End, and remain dedicated to serving the needs of our clients for years to come.



At East End Financial Group, we genuinely partner with our clients and work directly on your behalf with your other professional service providers, such as accountants, attorneys, insurance providers and even other investment managers.

This approach simplifies the process for our clients, is fully transparent, and enables us to ensure that all aspects of your plan remain on track over the long-term.

In addition, by regularly communicating with your key professional service providers, we are better able to anticipate and adjust to your needs as they evolve over time.

We partner with you and coordinate with your professional service providers to keep your plan on track.



At East End Financial Group, we truly take a team approach to meeting all of your needs. Providing consistent, concierge-level service for our clients has been our hallmark for over thirty years, and remains our top priority.

Simply put, when you need us, we are there for you. To ensure this, we employ an overlapping system of coverage, and keep key team members up to date on your account status so that, in the event your primary advisor is temporarily unavailable, your needs are still immediately met by a team member already fully versed in your account history.

We invite you to take the time to meet our team below or, better yet, in person. At East End, we are always there for you.

John Kosinski 2020

         John J. Kosinski

Our Founder, John Kosinski, passed away suddenly in July of 2022. John founded Kosinski Associates, Inc. in 1980, followed by East End Financial Group, with only $11,000, a telephone book and a dream.  With "A Commitment to Excellence" the East End Financial group was born.  From small beginnings the East End Financial Group grew to the large ensemble practice it is today providing services for small businesses, municipalities, and individuals. 

John was a graduate of Villanova University and went on to earn a master's degree in financial services from American College (MSFS).  He continued to receive credentials as a Chartered Financial Consultant® (ChFC®), Chartered Life Underwriter® (CLU®) and an associate member of the American Society of Pension Actuaries.

John always felt he had an obligation to give back to the community. He served on numerous Civic and Professional Boards, is a past President of the Suffolk County Estate Planning Council and the Riverhead Kiwanis Club, and Chairman of the Board for the Gwen L. Kosinski Foundation benefitting brain tumor research.  John spent over 20 years coaching Youth Baseball and Basketball teams in Eastport and Sag Harbor. He was also actively involved in the "Face of America" cycling events raising money for Disabled Veterans.

John grew up in Bridgehampton, and later made his home in North Haven before moving to the North Fork.  He said: "Outside of my family, the most important thing I've done in my life is helping hundreds of people reach their financial goals."

John's passing is a great loss for so many, but the legacy he built continues. Annmarie Zilnicki, now President, John's sons Joseph and Jack Kosinski and the entire EEFG team continue to uphold John's motto of a "Commitment to Excellence".
