The $3.9-million community rehabilitation and oncology centre welcomed its first patients on January 7.

The building features consulting rooms, a multi-disciplinary gym and an oncology unit with sweeping views of the Grampians.

Oncology patients are treated by visiting specialists from Ballarat Health, Dr Stephen Brown, Dr John Sycamnias and Professor George Kannourakis.

Stawell Regional Health chief executive Rohan Fitzgerald said the organisation was thrilled construction finished on schedule.

"The centre is magnificent," he said.

"It's very impressive for a regional town and we're so pleased to now be providing top health care to patients from all over the Wimmera in a modern, comfortable environment.

"Our oncology and allied health staff have settled in well and everything seems to be running smoothly."

Horsham farmer Bert Sprague has been visiting the oncology unit since the day it opened.

He attends weekly during three weeks of the month to treat pancreatic cancer.

"I'm expected to require treatment for about five months, so coming to Stawell is a lot easier than travelling weekly to Ballarat," Mr Sprague said.

"The facilities are excellent and the view is great. It's also quiet and peaceful."

The centre was funded by the Federal Government, a $180,000 State Government contribution, $120,000 raised by Callawadda shearer Aaron Hemley and several donations from community groups and clubs.
