Derrel Sims,  UFO Career highlights:

Discovered the alien implant phenomenon in 1960! Later pioneered research protocols, and orchestrated the first public surgeries and testing of alleged implants from the human body (1995).

First UFO researcher to be invited to lecture on “ Alien Implants” by the AMA, at a conference at John Muir Medical Center, on the “Medical Complications of Alleged Human/Alien Contact;” received  Letter of Appreciation (1994). This accomplishment was lauded by the late Dr. John Mack, MD, Harvard medical School.

Discovered phenomenon of “alien fluorescence,” an indelible, sub-dermal traces and patterns that often follow alien/human contact. (Circa 1992)

Derrel has in his possession the largest collection of physical evidence of alien/human contact including skin samples, DNA samples, XRays/MRIs, sonograms, objects with possible forensic traces (glass, wall, etc.), anomalous implants/artifacts expelled from the human body and surgically removed.

Pioneered revolutionary hypnotherapy techniques for reaching beneath screen memories—and Psychological “blocks”.  Some of these are as much as 3 layers deep.  Derrel discovered “screen dreams”, that are activated what a hypnotist, misses the memory of the event, and activates “recall”… Which is not memory at all.

First abduction researcher to initiate reaction from alien, via post-hypnotic suggestions installed behind the abductee’s subconscious.

Developed an extensive questionnaire for alleged alien experiencers employing a variety of analytical techniques including symbolic profiling drawings, handwriting analysis, Neuro Linguistic Programming ( NLP ), and hypnotherapy.

Who Is Derrel Sims?

More than forty years ago, Derrel Sims had his first encounter with an alien presence. As he grew older, he experienced a “less than benevolent” contact with these alien beings that would alter his life forever. As a result, at a young age, Derrel made the decision that he would no longer willingly, be victim to their bizarre quests. Later, this young boy learned how to manipulate some of the mental and physical techniques used on him by these “alien entities.” This would prove very useful later in his adult life as an investigator.

Determined to change his role in life from being the ‘hunted‘ to the hunter, he began to prepare himself for their pursuit. Every path he took, in life, would equip him mentally, physically and intellectually to become an investigator to find out “What they are doing, why they are doing it, why the subterfuge, and of course, Who are they!

As a result, Derrel has spent the past three decades researching the world of alien beings. His area of focus has dealt primarily with medical and scientific evidence of human/alien contact “from the abductee/contact the level. To that end, he has spent years studying and training in a broad range of areas that would provide him with a full array of skills necessary for his search to find evidence of these creatures.

From his accomplishments and certifications in Medical Hypnotherapy, Hypnotic Anesthesia, to his education in Graphoanalysis (handwriting analysis); he has pursued “Other talents” as well, to assist in his efforts to aid abductees, in reclaiming memories of their experiences.

In addition, to learning the methods for memory retrieval, Derrel has acquired considerable training in police, military and investigative work. He has included techniques from his martial art skills and scuba diving skills to assist in these investigations. These assets are critical to aid in the search, rescue and discovery of alien evidence.

This thorough and unusual approach has placed him in a category unparalleled, and often unenvied by others even in the UAP/Ufo field. His unique blend of personal history, coupled with his research and skilled investigative techniques prompts worldwide requests for him to share his knowledge. His last (circa 27 August 2022) presentation was online concerning “UBM’s (unidentified body marks) and traces of fluorescence left by the alien on abductees! This was presented to a cardiovascular surgeon, and other science and educators from Brazil, Spain, Switzerland and other places. The award of that presentation is presented below:

Being the first to discover, (as an Implantee himself in 1960) Derrel share the concept of alien implants, Derrel has been sought by those in the UFO community, as well as those within the medical and scientific communities, to share his breakthrough methods at world wide conferences. In addition to this global recognition, he has been acknowledged for his contributions via a series of awards and commendations. 

His acclaim is further recognized through the many requests he receives annually to appear on a variety of radio and television shows, where he shares his knowledge with thousands across the globe.

It is for these reasons, coupled with a passion that places him in the unequalled position of relating to those whose lives have been interupted, if not disrupted, that he pursues the “elusive Alien” and their secretive machinations.  

On a personal note, Darel went from a concerned observer/abductee to an Alien hunter of Evidence, once the alien came for his son at age 6.  

“Derrel’s statement of fact is simply that “you can take me, I’m a big guy I can handle it. When you come and take my six year old son and mess with his consciousness, I will hunt you down and find out who you are and where you are and what you’re up to I don’t care what planet you think you’re from or what dimension you think you come from. You’re not undetectable and I think I can prove it.”

Additional Information if needed:


Derrel Sims, over a span of more than 3 decades is a full ti me UFO Researcher with a specific interest in me dical/scientific evidence of human/alien contact. Sims feels that people who claim of contact with the alien presence should offer evidence of their positions. He states that it is incumbent upon us to produce evidence of these phenomena if we are to continue to make these claims and we must provide the best evidence to the medical/scientific fields if we are ever to have “academic” acceptance. So me of his work is already reviewed by the Royal Society of Chemical Engineers and is referenced in other works.

Sims is Board Certified Hypnotic Anesthesiologist and a Master Hypnotherapist, with special certifications in Medical Hypnotherapy and Hypnotherapeutic Intervention. He uses a multimodality approach to memory retrieval and has developed specialized techniques for working specifically with alleged abductees as well as for use in more typical therapeutic interventions.

He has a Master Level in Neuro Linguistic Programming (NLP), certifications in Ti me Line Therapy and extensive training in Graphoanalysis, Linguistics and other modalities. His eclectic background and Native American/Irish heritage contribute to his unique approach to life and his me thods of working with others.

Researchers and laboratories are used to exploit and further test his discoveries such as alien implants from cases that stem from 1960 and more recently the first public surgery for alleged alien implants in 1995. Extensive laboratory analysis of surgically removed implants has revealed objects with pathology and metallurgical findings that are so me what beyond our technologies. Each individual case is researched thoroughly and both physical and psychological profiles are taken prior to the procedure.

Sims travels to many parts of the world, conducting expeditions for new physical evidence, providing therapeutic interventions for alleged abductees, and as a speaker. As a UAP/UFO Investigator, he has gained the respect of the scientific world and spoke before 250 Surgeons and Doctors in an AMA sponsored program of continuing education concerning the topic, “Medical Complications of Alleged Human/Alien contact: Implants”. This was a first in the UFO field as well as the medical arena.

“I am confident that the best way to offer “Evidence” to those without a first-hand experience is to continue to pursue evidence collection, analysis, and presentation; to involve researchers and scientists of the highest qualifications, and to maintain rigorous protocols for collection and analysis.” …Sims.

This is the objective of Saber Enterprises and his work with a new “dream team” of scientists, researchers, and medical and mental health professions through FIRST (Fund for Interactive Research in Space Technology).
