Father & Son Team

Imagine the power of having two qualified financial planners working together to design a customized financial plan for you. They always say that two minds are better than one. But what about having two minds for the price of one?

When you work with O'Neil Financial, that is exactly what you will get. Bill and Mark work together as a team. We brainstorm, collaborate, and exchange our thoughts to deliver one great financial plan that is custom tailored to fit your unique situation. We work with you to ensure that your plan is successfully implemented from beginning to end. Also, we encourage you to meet with us frequently, so we can monitor the progress of the plan and make changes as needed.

The Father


William J. O'Neil started O'Neil Financial over 1982. He brings a tremendous amount of education and professional qualities to the financial planning table. Yet if you were to ask any of his clients what is the most important trait Bill had to offer before choosing to work with him they would say it was his integrity. Bill will be the first to tell you that finding a financial planner that you can trust and feel comfortable working with should be your #1 priority.

Bill O'Neil is a well known, reputable, and highly regarded financial planner throughout the community. He works diligently with his son, Mark, on each and every client they come in contact with to protect the reputation and integrity of the firm. As one of our clients, you will enjoy the same level of confidence and satisfaction that is shared amongst all of our investors.
