I cannot say enough wonderful things about St. John Kronstadt Care Center. We were so blessed that they had an opening when a family member needed rehabilitation. Having had around a dozen family members undergo short stays in similar facilities over the years, I can confidently say that St. John Kronstadt is in a league of its own. At every turn, we encountered truly caring, kind, and friendly people. They deeply understood the needs and wishes of both the patient and our family, and they did everything in their power to help us achieve the best possible outcomes. Even after the stay was over, they continued to support us by assisting with insurance, arranging follow-up care, and calling just to check in on how things were going. There is simply no other place like St. John Kronstadt Care Center.

St. John Kronshdat and Castro Valley have been a lifesaver for our family, especially for our grandmother. The staff there have been so compassionate, kind and loving towards her, making her feel at home. The facility is clean and well-maintained, and the rooms are spacious and comfortable. The meals are nutritious and well-prepared, and the staff are always ready to help with anything that grandma needs. We are so grateful to the staff for taking such good care of our grandma and for providing her with the comfort and security she needs in her golden years. The staff is always available to answer any questions or concerns that we have, and they keep us updated on her progress. We highly recommend St. John Kronshdat and Castro Valley to anyone in need of a caring and compassionate home for their loved ones.

The facility was austere did not offer many amenities. Staff were friendly and accomodating. There were two residents per room. There was only one shower room but several bathrooms for ease of access for residents. The recreation room was also the dining room. There was a small garden with a gazebo. Not much space for residents to walk around if you are looking for that kind of thing.
