About Us

About Our Firm

Background

We have chosen to limit our practice to tax preparation and advisory services and business and individual planning and consulting. Consequently, we do not provide many of the more traditional services expected of a Certified Public Accounting Firm such as bookkeeping services, payroll processing, audited, reviewed or compiled financial statement preparation, investment management or detailed personal financial planning. However, through our extensive network of firms with which we have long-standing relationships, we are able to coordinate and oversee the delivery of these services to our clients.

Our Mission

Our mission is to assist our clients in achieving their financial goals through thorough research, sound analysis, and quality compliance and consulting services delivered with high standards of integrity, objectivity and professionalism.
