The Marston Company was an anchor of the original mall. With the completion of the complex, the rivalry between May Company and The Broadway was extended from Los Angeles to San Diego. May Centers had built MISSION VALLEY CENTER. Broadway-Hale Stores (under the auspices of its Marston's subsidiary) now presided over their GROSSMONT.

On the opposite end of GROSSMONT CENTER was Montgomery Ward. The store was comprised of 2 levels and 122,000 square feet. It included an attached Wards Auto Center.
