Dr. Mahnensmith's bio

This content was provided by Dr. Mahnensmith "I am a God-Revering, God-Loving Servant-Physician. I grew up in rural Indiana. Worship, Basketball, Baseball and Swimming were my passions. I have loved reading. I attended College in Granville OHIO. I attended Medical School at Yale. I married in 1974, uniting in covenant relationship with my best friend and my girl friend of childhood. We have two children, now adult. We have 4 grandchildren, whom we love dearly. I love Schnauzers. I love caring for them. I have served at Duke Hospital, Medford Clinic, Rogue Valley Hospital, Miriam Hospital, Yale New Haven Hospital, Connecticut Childrens Hospital, and Stay Well Community Health Center. I have provided Geriatric Care in four Nursing Homes and I have loved all. I love Gospel Music, Classical Music, Bible Reading, Devotion Reading, Teaching, Gardening, Walking and Biking. I love time with my wife and time with our adult children and their children. I am relational and love to connect with people. I live in Simsbury CT with my wife and with our Schnauzer Jesse - we moved here from New Haven CT to be next door to our grandkids and their parents - to participate in their care and their life daily. We are setting into a small village within Simsbury, which is wonderful. I often ponder life and living and often consider life from the perspective of relationships and sharing and caring. I aim to be faithful to my Call as Servant-Physician, Husband, Father, Grandpa, and Disciple of Jesus Christ. "
