Chicago-based architectural firm Harley Ellis Devereaux (HED) is joining forces with Deems Lewis McKinley (DLM), a 57-year-old architecture and engineering services firm headquartered in San Franicisco.

The merger, whose terms were not disclosed, is expected to strengthen HED’s presence in the K-12 and Community Education markets, where DLM has established itself as a recognized leader. (Its tagline is “Improving Education through Design,” and 95% of its clients are educational institutions.)
