WESTBOROUGH, MA-In a transaction that brings the property to full occupancy, WorkflowOne Inc. has leased 116,000 sf at 1-5 Sassacus Dr. The pact is a renewal and expansion more than doubling the firm’s presence in the 165,000-sf building. The remainder is leased to Relizon, a business communications company.

Both deals were struck under the stewardship of Invesco Realty Advisors, which has owned 1-5 Sassacus Dr. since 2000. Consummated in 2004, the 51,000-sf Relizon lease even featured the same brokerage firms in Richards Barry Joyce & Partners representing the Dallas-based landlord and Cresa Partners bringing in the two tenants. Cresa VP David Ross from the firm’s Boston office and colleague David Reinhart were involved in both leases. RBJ principal John Lashar, who also negotiated the Relizon lease for Invesco, was on that end again in the WorkflowOne lease, joined in the latest deal by RBJ VP Paul Leone.
