Su Walker As a professional clairvoyant and medical intuitive for nearly thirty years, Su Walker has been featured on both national and international television. Su is also a lifelong experiencer of ET/UFO phenomena. In September 2013, she was unexpectedly contacted by an extraterrestrial while visiting the Albuquerque, New Mexico area for the first time. A strong friendship with this ET, nicknamed Sandia, began to develop with she and her spouse, Rev. White Otter. For the past five years, this couple has continued to dialogue with and translate for not only Sandia (Commander Tlkm) but also several other extraterrestrials who operate out of a facility beneath the Sandia Mountain. Since June 2015, together Su and Otter have volunteered more than 10,000 hours assisting in telepathic translation for the Twitter account @sandiawisdom.
