To start with, their calling it Atlantis Healing tells me this has very little to do with Native traditions. Sometimes they're claiming Guarani traditions, sometimes Cheyenne. What they call Cheyenne traditions seem to be once again H Storm's version of medicine wheels.

The word Ma'heo'o is Cheyenne, Native American language. This system of energy works will combine the elements of Earth, Air, Water and Fire with the Great Spirit to effectively promote and activate healing in the human condition...The first 4 represent the elements and enables us to connect with and channel Mother Earth's energy Combined with and activated by Great Spirit this becomes a very powerful system promoting great energy channeling ability, use of healing light and color, higher intellect, grounded-ness... It can bring you into contact with your spirit totems, give you your sacred name and balance your body with the 5 elements... Ma'heo'o Reiki was created by Sheryl Carter and employs symbols derived from the Native American Peoples and Mother Earth."
So pretty much it's just using symbols or names they claim are Native. Those "four elements" are old European magic ideas. This is all pretty recent, based on Carter's book published only two years ago. Already they're sometimes claiming it as a "tradition" and even that it's being taught to help Natives, even though all the people they market to sure don't seem Native.

The Ma’heo’o Reiki tradition is one that was established in order to focus on Native American traditions for healing.
Ma’heo’o is translated into meaning the Great Spirit or Great One. It is translated from a Cheyenne word. It is known to be important to this tribe because it moves from the Great Spirit to use energy that combines the four elements of the earth. These elements are the earth, air, water and fire. By calling on these elements and energy, one is able to heal.
While this method employs several different types of traditional Reiki method, it also uses different atonements and symbols in order to focus on the Native American lifestyles and ways of living....

Native American Traditions

Higher consciousness in relation to this is also important with this type of Reiki training. In relation to Native American traditions, it is also sometimes used to bring spirit totems, animals and sacred names to one’s life....
You can easily find several sessions through the internet or by doing research. By combining Native American traditions with Reiki, Ma’heo’o Reiki is known to be able to call on different elements and energies from the universe in order to allow for healing and self-empowerment.
This combination of two traditions helps improve ones ability to heal and reach higher levels of consciousness."
Many of the people teaching it seem to mix and match just about every quick fix belief, seminar, or teaching out there.
