Marc Rosenblum - CEO, Founder

Job Titles:
  • CEO
  • Founder
  • CERTIFIED FINANCIAL PLANNER
Marc Rosenblum is an experienced and skilled CERTIFIED FINANCIAL PLANNER™ professional. How I entered the financial advisory business, and later hung out my own shingle in the ‘80s to specialize in wealth preservation and retirement planning, originates when I was a child. Before my 6th birthday, my dad died. That was devastating, but worse was watching my mom struggle as she raised three young kids on a teacher's salary. So, as a teenager, to earn my own money and ease some of my mom's burdens, I mowed lawns and worked odd jobs, and in high school and college I sold hot dogs and beer at Phillies and Eagles games - what a gig for an avid sports fan! It was hard work, but I was okay with that. I accepted my circumstances, rolled up my sleeves, and went to work. Soon I started at Temple University in Philadelphia where I majored in business finance and marketing. That's when I started my first job with a life insurance company. Times were different back then, and I went door to door selling policies. I met so many people, put together suitable policies for them, and remain friends with many to this day. Later I worked with an independent life insurance agent, and that led to helping clients with investment and retirement plans. I needed to be licensed to do this, so I studied for and received all the licenses and certifications necessary to be a top financial advisor and planner. Then I decided to take a risk and go out on my own because I'd become very skilled at strategically customizing plans and selecting the most appropriate products necessary to implement those plans. Also, with my mom, there was a need and, finally, an opportunity for me to help her manage her finances and plan for retirement. I wanted to bring my skills and experience to the community as well because it was clear that most people wanted to have a retirement nest egg but had little idea how to start or to make necessary adjustments as they grew older and as their life circumstances changed.
