About RHL Accountants

Rooted on Chicago’s North Shore, RHL Accountants serves individuals and businesses across the region and throughout the U.S. The firm was built on a simple belief: clients deserve proactive, personal guidance all year, not just at tax time. Founder Robert H. Lewin brings over 40 years of experience as an IRS-licensed Enrolled Agent and Certified Tax Resolution Specialist, delivering trusted advice with integrity and care.

The Journey That Shaped Us

RHL Accountants (Robert H. Lewin, Ltd.) grew from a referral-driven practice built on trust, care, and a hands-on approach clients quickly came to rely on. From the beginning, our focus has been on long-term relationships—not transactions—and on taking ownership of complex financial matters so clients don’t have to. As the firm has evolved, so has the depth of our services, allowing us to support individuals, families, and business owners through changing financial needs with clarity, responsiveness, and confidence.
