Summer Street's manufacturing roots run deep.  We understand that containing costs, achieving delivery times and managing supplier and customer relationships is critical to remaining competitive.  Even the best of companies can be challenged by stagnant demand, escalating material costs, and aggressive competitor pricing.  The right investments now can often improve flexibility, responsiveness, safety and quality.  Our goal is to help companies create real advantages in both expansion and contraction cycles.

Our management partners will tell you that we seek to grow their companies’ profitability by investing in the equipment, systems, and people that enable them to beat out the competition, fair and square. We’ve helped companies to implement lean manufacturing processes that shaved delivery times by 50%, acquire product lines that doubled sales, and automate production lines to increase gross margins by 20%. The kinds of companies we’re looking for make a proprietary product, one that they’re known for throughout their industry, and they manufacture it efficiently enough to make a healthy margin.

If you could use a partner who isn’t afraid to get their shoes dirty on a plant tour, we look forward to meeting you.
