John DiMatteo, CFP®, AIF®

CEO | Financial Advisor

I grew up in Stratford, Connecticut, in a close family with almost all my relatives living nearby. We enjoyed Italian feasts on a weekly basis with all of them, and it was so special having my grandparents with us. I attended Bunnell High School and played football, basketball, and baseball as a kid, including with the Stratford Eagles National Championship team of the early ’70s. (We tied 0-0.)

At the University of Connecticut, I joined Sigma Phi Epsilon fraternity and met many great friends whom I remain close with to this day.  I earned a bachelor's degree in chemical engineering because at the time I liked math and science.  When you're young, it is difficult to know exactly what and where you want to be. 

I moved to Houston, Texas, shortly after graduating and made my first bad investment in Houston real estate.  I worked in the oil production service field (mud engineer) for two years and then sold Teflon-lined valves to the chemical industry for three years, and enjoyed traveling the country. 

Family values stay with you for life.  The opportunity arose to join my mother and father’s property/casualty insurance business, and I soon decided I liked working with and helping people much more than math and science.  The decision was timely because I moved back to Connecticut and met my beautiful wife, Kim, shortly thereafter.  Kim also joined the firm, along with my three sisters and brother-in-law.  Our parents taught us early the virtues of hard work and always putting our clients’ needs first, as well as the importance of giving back to the community we serve.  I believe this is why we successfully grew the firm from a small 500-square-foot office to a thriving 5,500-square-foot building in Shelton with close to 30 employees.  We serve thousands of families in the Fairfield and New Haven county areas, providing all types of property/casualty, life/health insurances, tax and accounting services, and comprehensive financial planning services.

In 1993, I obtained my CERTIFIED FINANCIAL PlANNERTM professional certification, and I’ve focused on the financial planning side of the business ever since.  I really feel my strength in mathematics and science have been a benefit to our clients, especially my attention to detail. I take great pride in working with my nephew and godson, Johnny Esposito, who represents the third generation of the family, joining the firm in 2017; and Diane Lemanski, my wonderful financial assistant who has more than 30 years of experience.  Having the next generation learning the business now ensures we will be here to help your next generation, too.

In 2005, we created the DiMatteo Family Charitable Foundation in honor of Tony as he successfully battled colon cancer. To date, we have raised more than $400,000 for various local charities including the Kennedy Center, Boys and Girls Club of the Lower Naugatuck Valley,  Spooner House,  BH Cares, and many other worthy causes over the years.

I’m lucky to be married to Kim, and we have three fantastic children (yes, that’s a proud father talking!). Our oldest son, Anthony, graduated from the University of Connecticut and works for a large national insurance company; our middle daughter, Jessica, attends the University of Connecticut; and our youngest son, Michael, attends the University of Tampa. 

Our family enjoys traveling, especially to Redington Shores, Florida, and Florence, Italy.  We are active and exercise regularly, especially racquetball and horseback riding. Kim grew up riding on her mom’s horse farm in Bethany and her passion for horses has rubbed off on Jessica over the years. We now have a horse stable at our home and enjoy riding on the trails of Bethany regularly.

John Esposito


I am originally from Shelton, Connecticut, and have lived there all my life until recently moving to Middlebury, Connecticut, with my beautiful wife, Amanda, and son Luca. I grew up in a close-knit Italian family on both sides, the Espositos and DiMatteos. I attended Shelton High School where I played soccer and became a part of the founding lacrosse team in 2004.

In 2008, I was accepted into Western New England University on a lacrosse scholarship but ultimately decided to join and help found WENU’s rugby program. We won the NERFU D4 championship the first year as a team. I still support the rugby team to this day by donating and playing the annual WNEU Rugby Alumni game. I received a bachelor’s degree in finance in 2012.

During summers while in school, I did everything from servicing pools, install cubicles, intern at Sikorsky, and travel the country organizing 3v3 soccer tournaments for kids. In my junior year of college, I met and started dating my future wife, Amanda.

One of the highlights of my college career was getting the opportunity to study abroad in Florence, Italy. There, I was able to visit my family roots in Calabria, Abruzzo, and Naples and meet some of my cousins and visit with an aunt and uncle, whom I hadn’t seen since I was a toddler.

After graduating from college, it was tough finding a job as the economy and job market were still recovering from the great recession of 2008. In the meantime, I went back to working on pools and cleaning windows and eventually found a job in Boston developing business for a corporate payment and foreign exchange trading solutions company based out of Canada. After a short while there, I received a call to interview at GE Capital in Norwalk, Connecticut. It was a great opportunity, I took the interview and landed the job as a portfolio analyst in commercial lending operations. Two years later, the news hit that GE was selling off the lending business and our jobs would be terminated.

I thought this would be a great time and opportunity to follow in the family footsteps and join the business that my grandparents built. So here I am today, enjoying coming into the office; seeing my mother, two aunts, and two uncles; and being able to work with them on a professional level to help grow the business and pass on the legacy of my grandfather and grandmother to a third generation.

I truly enjoy what I do now: helping people just like myself, sometimes older, sometimes younger, prepare for and navigate through retirement. I also love helping small businesses take their practice to the next level in setting up retirement plans, finding the best fit for them, and training their employees on the benefits and investments within the plan.

My time is mostly taken by my young family and continuous home improvement projects. However, in my spare time, I enjoy hunting and fishing, woodworking, and mixed martial arts.   

Diane Lemanski

Financial Assistant

I am originally from Long Island in New York and attended high school and college there. I graduated from Queens College, City University of New York with a BA in accounting and worked in Manhattan for New York Life Insurance Company for 10 years in investment and financial accounting. My family still lives on Long Island so I am often there to visit them and my many lifelong friends.

I continued to commute to my job in New York by train after getting married and moving to Shelton, Connecticut, my husband’s hometown. When our daughter was born in 1994, it was the right time to change jobs and work closer to home. I started working for a local CPA preparing tax returns and the bookkeeping for our clients' small businesses. Our son was born soon after and I was happy that I could continue to work in my field doing something that I enjoyed. Some years later, I began working for an Enrolled Agent who was also a Financial Representative. It was great to combine my tax and accounting experience with various types of investment products for individuals and families. I joined DiMatteo Financial in 2017 as John DiMatteo’s financial assistant and I also assist in the Tax department with individual tax returns during tax season.   

I enjoy my job very much especially being able to help our clients achieve their financial goals. It is very rewarding to help them save for retirement, college, and for the short-term and to assist them with their financial questions. My husband has been in a financial career for many years and our two children are recent college graduates. They are following our path in the business world and work for large companies in Philadelphia and Chicago.  We spend a lot of our free time visiting them and looking for interesting places to go on family hikes.  My husband and I are also busy with our aging parents who need a lot of our assistance now. This has helped me in my position at DiMatteo since retirement planning is a big part of it.  I am very grateful for the opportunity to work at DiMatteo Financial.
