ISI Financial Group, Inc. is a 100% Fee-Only, independent Financial Advisor and Fiduciary located in Lancaster, PA. Because we are Fee-Only advisors, clients sincerely appreciate that we sell no financial products and are paid only for advice, guidance and services. Our clients come to us seeking peace of mind and financial security as we assist them in developing and establishing a clear path to their goals. When planning for your retirement, or already in retirement, it is important to have a team by your side to help you create a blueprint for building your financial house. At ISI we help our clients "sleep well at night" by taking them through our holistic, comprehensive financial planning process and offering a unique experience to each individual, family or institution that we work with. And for those who may not be seeking comprehensive wealth management services at this time, we offer hourly consulting only, to help answer any specific questions you may have, or perhaps you just want a second opinion of your current financial situation from an independent, unbiased advisory firm who you know is legally bound to put your best interests first – always.

Developing a concise, goal-oriented, comprehensive financial plan and then implementing it with the guidance of a trusted, financial fiduciary, is paramount to achieving Financial Freedom and Peace of Mind.


As a member of the National Association of Personal Financial Advisors (NAPFA), we are bound to a written fiduciary oath to always represent our clients’ best interests in all we do. One of the most important ways this is demonstrated is in how we are compensated. Quite simply, as a Fee-Only advisor, we receive no commissions or any other form of compensation from anyone other than our clients. This is something that our clients value greatly and why they confidently put their trust in us without worrying about conflicts of interest. This is in stark contrast to the majority of other firms who often sell products and receive additional forms of compensation. There is a major, significant difference between a Fee-Only and a Fee-Based financial advisor. CLICK HERE to learn about the difference.

Also, we are happy to provide you with a free, consumer-friendly checklist, which you can print out and use in helping you wisely interview any financial advisor to assure you only develop a relationship with a true, Fee-Only Financial Fiduciary.
