MedReach Application for Improved Access to Specialty Patient Care

Trestle Holdings Inc., (OTCBB:TLHO) a supplier of tissue imaging and network medicine applications, announced today that Maine Health Alliance (MHA), a non-profit organization consisting of approximately 325 physicians and 11 hospitals in Northern Maine, has purchased the company's telemedicine product, MedReach.

MedReach provides real-time integrated medical data sharing among physicians and patients while enabling the remote examination, diagnosis, and treatment of patients.

Using the company's MedReach system, MHA will now offer specialty care to underserved rural patients in Northern Maine by linking six rural sites to the St. Joseph Healthcare System. The participating sites in Maine include Cary Medical Center in Caribou, Maine Coast Memorial Hospital in Ellsworth, Mayo Regional Hospital in Dover-Foxcroft, Penobscot Valley Hospital in Lincoln, and St. Joseph Hospital in Bangor.

"The lack of access to specialty health care has been identified as a statewide concern for Maine and we are excited that we now have the technology to help address this concern," said Sister Mary Norberta, C.S.S.F., FACHE, president and CEO, St. Joseph Healthcare. "We want to be able to provide the best possible care to our patients without having them worry about transportation. "

"We are very pleased to be collaborating with Maine Health Alliance to improve healthcare access throughout the state of Maine," said Michael Doherty, chairman of the board of directors, Trestle Holdings Inc. "We look forward to working with additional healthcare providers, like Maine Health Alliance, to improve patient care through implementing our telemedicine technology."

In addition to improving access to specialty care for rural patients, MHA plans to utilize MedReach to offer distance learning opportunities and continuing education medical courses to isolated health care providers via the Internet. MHA is expected to go live with MedReach in January 2004.
