Our Firm

Making Lives Better

At HeimLantz, we work towards a simple but profound goal: making lives better. We are dedicated to serving our clients, serving our teammates, and serving our community. As a part of our mission to make lives better, we adhere to the following core values:

We are eager to partner with you in pursuit of your business and personal goals. Our professionals are so much more than just accountants—we are loyal advisors. We are excellent at what we do and we love doing it! 


HeimLantz was established in 2001 when Carter Heim and Tom Lantz—who each grew successful accounting practices from the mid-1970s through the 1990s—chose to merge their firms. Today, the firm is backed by nearly 50 years of experience. Operating out of offices in Annapolis, Maryland, Alexandria, Virginia, and Lexington Park, Maryland, the HeimLantz team of professionals serves organizations throughout the mid-Atlantic, with a particular focus on the greater Washington D.C., Annapolis, Baltimore, and Northern Virginia metro areas.

Client Satisfaction

At HeimLantz, we utilize the Net Promoter Score to gauge our clients’ satisfaction, identify our strengths, and discover areas of improvement. The survey assigns a score based on respondents’ answers to one simple question—“How likely is it that you would recommend HeimLantz to a friend?”—and the reasons for the rating they give.

We are grateful to share that on our most recent survey, we received an overall NPS score of 88 (on a scale of -100 to +100). This puts us on par with customer service leaders like Tesla (97) and Apple (89). Additional insights from the survey include:

  • 100% of our clients feel we exhibit courtesy and professionalism
  • 100% of our clients feel we demonstrate the appropriate level of technical expertise
  • 100% of our clients feel we produce high quality materials
