About Us Located in the foothills of the scenic Sierra Nevada Mountains, Cascades of Grass Valley welcomes you to a beautiful, homelike community that puts the California Gold Rush Territory at your doorstep. You’ll find us nestled in a quiet, wooded area just minutes from shopping, banking, dining and the Sierra Nevada Memorial Hospital. And we’re just a short drive from historic Nevada City and the Sacramento metropolitan area. Cascades of Grass Valley Lakes offers Assisted Living in The Manor, where you can relax with family and friends in the fireside lounge, play cards and sip coffee in the lovely garden courtyard, or take part in any of our many scheduled activities. We’ll help with whatever you need, from medication assistance to wheelchair transportation to getting you to your monthly bridge club gathering.
