Our Mission & Philosophy

The mission of Healing Grove Health Center is to share the love of Jesus through Health Care, Soul Care, and Culture Care, thus bringing "the healing of the nations" to our community.

True healing is only experienced once our bodies, minds, and souls are each restored. At Healing Grove Health Center, we achieve this intensive restoration for each patient through cutting-edge, personalized care. By wholly mending our individual health, we can gradually heal our neighborhoods, our communities, and our world.

Restoring your health     |     Understanding your soul     |     Empowering your culture

“Then the angel showed me the river of the water of life, as clear as crystal, flowing from the throne of God and of the Lamb down the middle of the great street of the city. On each side of the river stood the tree of life, bearing twelve crops of fruit, yielding its fruit every month. And the leaves of the tree are for the healing of the nations.

No longer will there be any curse. The throne of God and of the Lamb will be in the city, and his servants will serve him. They will see his face, and his name will be on their foreheads. There will be no more night. They will not need the light of a lamp or the light of the sun, for the Lord God will give them light. And they will reign for ever and ever.”

Revelation 22:1-5

Our name “Healing Grove” comes from the passage above. In this passage we are given a beautiful image of heaven, where God’s lush river nourishes the city. The trees along the riverbanks bring healing – an allusion to the Tree of Good and Evil that brought death in the Garden of Eden. However, the trees don’t just bring healing to individuals; they bring healing to entire nations.

It’s a profoundly holistic vision of healing in the Kingdom of Heaven. That image of healing inspires us at Healing Grove Health Center to bring holistic healing to the city of San Jose. It’s our hope that a diverse group of nations right here in our city comes together to seek after God’s healing.
