And many more. Numbers have always been my passion, and fortunately for me, I’m passionate about people too. And when you connect numbers with what they mean to people, you can transform the financial planning experience. That’s what drives me.”

Ken Koppitz

Ken Koppitz Senior Wealth Advisor / Registered Principal
Investment Advisor Representative of Commonwealth Financial Network. Series 7, 24, 63, 65
Licensed in 14 states

Ken enjoys challenging people to grow and encouraging them to pursue things they might not otherwise have done had they not met him. He thinks of what he does as legacy planning – but not in the traditional financial planning sense of the word.

“Over the years I’ve witnessed clients in their later retirement years start to think about how they will be remembered when they’re gone. By starting to think about this sooner rather than later, clients are more likely to feel a sense of fulfillment with regard to how they’ve lived their life and their ability to make the world a better place. It’s not necessarily always about the numbers in the account, but oftentimes it can help these legacy-defining activities happen.”

Growing up without much, Ken’s parents emphasized hard work and savings. He got in the habit of saving a portion of every dollar he earned whether it was from birthdays, holidays or from his paper route he started when he was twelve. Through his own savings, he was able to buy and race BMX bikes as a kid and purchase his first car at 17. Ken found great satisfaction in saving, knowing that by simply deferring the gratification he could accomplish something with far greater impact that really mattered to him. He now enjoys helping others do the same.

Ken and his wife Michelle enjoy spending time with their two kids and dog. Music is a constant in the Koppitz household – both listening to and, for the kids, performing. And, Ken has never outgrown playing cars with his friends – he enjoys driving on tracks throughout the country, providing classroom instruction and in-car high performance driver coaching. Additionally, he’s been involved in Audi Club’s Teen Driving Clinic helping refine the driving skills of hundreds of new teen drivers over the years.

Jodi L. Manthei

Jodi Manthei Senior Wealth Advisor / Registered Principal
Accredited Investment Fiduciary (AIF) Series 7, 24, 63, 65
Registered in 23 states
Life Insurance Licensed

Jodi summarizes her work philosophy with three words: Listen. Organize. Guide. She listens to clients and thought leaders, organizes economic data, market trends and client information, and makes it all personal by providing guidance in financial planning and portfolio management.

“Connecting to people and organizations with shared values of integrity, positivity, perseverance, compassion and the spirit of generosity has been the most amazing experience of my life.”

My grandfather was an international business consultant. As a child, I visited his office and he explained how they reviewed all the pieces of a company and developed a strategy to help the company get stronger. I loved the idea of taking those puzzle pieces and putting them together to help individuals and families. As an Advisor, my passion is to guide clients to make good decisions. Ultimately, I saw the resulting sense of well-being created in my clients once they had a plan and someone they trusted to share their goals and concerns. Our clients are phenomenal people who I enjoy and learn from every day. I truly care about them and am humbled and amazed at the many ways in which they express their appreciation.”

Over the years, Jodi’s clients have watched her raise four very active children which included the usual sports, music, and urgent care visits. Whether they are hanging out by the backyard grill, traveling, golfing, hiking, biking or playing Scrabble, their high energy friends and family tends to expand to include just a few more loved ones… or loved-ones-to-be.

Above all, Jodi loves making connections. Just like her father, her brain automatically goes to “What do we have in common that will help me know you better?” She met her very first client walking home from Wall Street on her way to the NJ commuter train. A few words started a conversation and by the time they reached their destination, he said, “I could use an IRA. Maybe we should talk more.”
