NEW YORK, February 13, 2004 - Sentinel Capital Partners, a leading private equity firm that invests in smaller middle market management buyouts, is pleased to announce the sale of its subordinated note holdings in Castle Dental Centers, Inc. in a recapitalization transaction. Headquartered in Houston, Texas, Castle Dental develops, manages and operates integrated dental networks in Texas, Tennessee, Florida and California. Castle Dental provides general dentistry, orthodontic and other dental specialty services through 76 dental clinics with approximately 200 affiliated dentists.
