About Seneca
Healthcare District

Seneca Healthcare District was formed in 1947 as an independent special district to meet the needs of our rural community. The hospital opened the doors to patients in 1954. The Skilled Nursing Facility admitted the first patient in 1976. The hospital based rural health clinic was built in 1996. Seneca received Critical Access Hospital designation in 2007 and is a non-profit governmental entity supported by tax dollars.

Seneca Healthcare District is a community-oriented critical access hospital and clinic, located in the beautiful Lake Almanor area with a full range of inpatient and outpatient care. Services include diagnostic imaging, emergency, medical and surgical care. Seneca is more than a hospital; they are a partner in health and wellness both inside and outside its walls. As the healthcare industry becomes more streamlined and impersonal, people are looking for a health care setting that feels more like a family. Seneca strives to provide that kind of family environment by never forgetting that people come first. Seneca is dedicated to patient safety and quality care, which is why they are constantly working to be the provider of choice for their community. They do this in a manner that encourages the efficient use of resources while providing a working environment that promotes the personal and professional growth of their employees.

About Lake Almanor Area

The Lake Almanor Basin and surrounding Lassen National Volcanic Park and Lassen National Forest area spread across a natural wonderland created by millions of years of geologic forces, a crossroad where the granite of the Sierra Nevada meets the lava of the Cascades. Lake Almanor has 52 miles of shoreline located by Lassen Volcanic National Park which boasts the southernmost volcano in the Cascade Range. This area is a playground for all seasons, for all ages and any lifestyle. ​

I have been working at Seneca Hospital for a little over 6 years. The wonderful people I work with are not just fellow staff members, they are family who love and care for each other. They extend that love and care to our patients and their families.

I was born in this hospital and it’s refreshing to work here so many years later in a supportive environment that understands the importance of family!

"I was treated so good. Everybody was kind. I was there for shortness of breath and there were instantly,
3 people taking care of me... treated like friend or family more than patient... only place I will go."

This is a wonderful hospital. Being a transplant city girl, I feel so welcome there. The receptionist, the triage nurse. All the nurses, the doctors, respiratory care specialists, x-ray technicians... are all wonderful.
Every time I've gone there, I have been pretty sick. I was helicoptered out more than 3 times from Seneca. I kept saying can't you help me here? No, you need to go. Because all the folks at this hospital really do care about people.
The medical world would be better if these wonderful health professionals could be everywhere.

Thank you. To all the doctor's nurses and entire staff at Seneca!

You truly are the greatest!!!
