The types of service firms that Sterling focuses on include law firms, real estate management companies, not-for-profit companies and staffing agencies. Millman added that "approximately 80% of the loan growth is from new client relationships," and that the "sweet spot" for the loan growth is "companies with credit needs between $3 and $10 million dollars. We find that that is an under-served market place." Millman says that the lending market in New York City is "a very resilient market with tremendous density of small and mid-sized businesses," and with Sterling having such a small market share, "the opportunity for market growth is essentially unlimited for us. That's coupled with the fact that a number of banks are less interested in lending to small and midsized companies than we are." -- Written by Philip van Doorn in Jupiter, Fla.
