About Us

Who is Edward Jacks & Company, LLC?

We are one of the oldest small accounting firms in the area - but don't let that fool you. Edward Jacks began private practice over 75 years ago. The firm continues to flourish as son and partner, Jerrold P. Jacks, along with other professionals, provide quality accounting and related services to an ever-increasing group of excellent customers.

Based in Lake Forest, Illinois, we are a family-oriented firm knowledgeable on the needs of a range of today's growing businesses. We form a strong personal and professional bond with our clients because we learn their business needs and offer "hands-on" participation. Many of our clients have been with our firm since we began business, and together we have grown side by side.

Take a few minutes to look over the many services we can provide your organization. While we offer all of the traditional services of a CPA firm, including accounting, auditing and tax preparation, we also offer a number of specialized services. In response to changes taking place in business, finance and tax law, we have developed strength in a variety of management and financial services such as short and long term planning, systems, budgeting, forecasting, financial and tax planning. Our compact size and staff caliber enables us to competently address problems promptly.

Let us help you put your mind at ease. Our staff is committed to taking good care of our clients, meeting their needs and requirements. By doing so, we believe our clients will take care of us. This philosophy has been successful for over 75 years as we pledge the highest level of professional customer service. We would welcome an opportunity to demonstrate our abilities in any capacity and an opportunity to serve your firm.
