"I was diagnosed with triple-negative breast cancer, stage 2b, in April 2023. They recommended chemotherapy and immunotherapy simultaneously. A friend of my mother's, who was also a patient of Dr. Sandra’s, referred me to her. Sandra’s deep knowledge and wisdom about the microbiome and internal balance were crucial for me in detoxifying from chemotherapy and regenerating my health and internal balance afterward. Her guidance helped me navigate through the vast information available and focus on what was most impactful for my healing.
Sandra's support also strengthened my connection on an energetic and spiritual level through meditations, prayers, mantras, and chants. She guided me to connect with myself in profound ways. Considering chemotherapy was the hardest thing I’ve ever done; those meditations and mantras and singings provided me with strength and a deeper connection to myself during the most challenging time of my life.
I share this because if there are others going through a similar journey, they should know about these complementary approaches to help them heal and navigate such a tough treatment. More than anything, it’s about finding oneself, recovering, and healing."
Ariana Moore, Texas. USA

“I'm Jason from Massachusetts, USA. Dr. Sandra literally saved my vacation, I had food poisoning and lost consciousness at breakfast, Dr. Sandra was at the next table, she realized what was happening, she came immediately; She gave me electrolytes. Colloidal silver, activated charcoal, he gave me the schedule to take all this in 8 hours, I was feeling much better, here I am 24 hours later and I feel very good, I was able to eat again and I feel full of vitality, Sandra literally saved my vacation “Thank you Sandra.”
Jason. Massachussets, USA

“Hello, I want to share my testimony, which was wonderful, with Dr. Sandra Rangel. I did my treatment approximately 4 years ago, at that time I managed to lose 8 kilos, kilos that I had not been able to lose since I had my daughters. Apart from losing weight, I achieved other very positive things in my life, among them was that I managed to gain a lot of energy. We did the treatment with supplements, food, readings and more. All this helped me a lot to learn to eat better, better lifestyle and to be able to apply it also at home with my husband and my daughters. At this moment I have managed to maintain the weight that I managed to lose at that time and it has been wonderful, thank you!”.
Maria Cecilia Puente, Colombia. (Overweight and optimum health)

“This is not only a thank you, but also a congratulations and a life testimony for Dr. Sandra Rangel. Her coach has truly been wonderful. I have confirmed this over the years. It has been a blessing in my life to have found her, because I was able to change many habits that I had and that has contributed to improving my health, improving ailments that I have had, and above all, to becoming aware of what is best for my body and mind and also for my family. I truly invite you to get to know her entire protocol. I have tried other doctors and I always, always conclude that Dr. Sandra is extremely comprehensive, so I have no choice but to congratulate her, thank her, invite you and give you my testimony that her entire methodology truly transformed my life.”
Jenny Amaya. Miami, USA. (Overweight and optimum health)
Hello, my name is Derly Olarte, I live in Dubai and today I want to share my testimony about the process I have experienced with Dr. Sandra Rangel. Thanks to all her knowledge and light, she has been a great guide on my path that has allowed me to learn and make changes in different aspects in favor of a much healthier and quality life.
Thanks to her, my healing process has been wonderful, full of growth and learning; of being more conscious and understanding the way to feed my physical and spiritual body. Thanks to her, I WOKE UP and understood the damage that sweets and flour cause to my body, and that there is a way to eat delicious and nutritious food based on organic ingredients, gluten-free, without added sugars and without genetic modifications.
I made many changes to my habits, and I can not live without them anymore.
These habits strengthened different systems of my body such as the immune system, the nervous system, the digestive system, etc. They changed the texture of my skin, my hair, and I experienced the difference between a vital, light and energetic body; to a heavy body, low on energy and full of toxicity.
Today I thank life for Sandra, for being part of my path, for sharing each of her knowledge with me, for helping me in this stage of healing, for all the love she transmits, and for all the benefits that are reflected in me thanks to this holistic work.
Thank you Sandra for all your love and all your energy, may there be many more people who have the opportunity to heal by your side.
Derly Olarte Camargo, Dubai.

“Thank you for placing Dr. Sandra Rangel in my life; she has taken such good care of me. With Your help, she has worked with me through the good times and the not-so-good times because sometimes I have felt sad, but Dr. Sandra, with the words God puts in her mind, has never let me fall. Here I am, still in God’s hands, with Dr. Sandra’s treatment. I had no strength left; the pain was too much, which is why I say that God placed this doctor in my life.”
Socorro was diagnosed with stage four cancer with multiple metastases when she first came to my consultation. After going through chemotherapy and other treatments, she was tired of battling cancer and wanted a different approach, which led her to seek my help. During our treatment, her cancer stopped progressing, she changed her lifestyle, lost excess weight, regained hope and purpose, and even started her own organic garden!
Socorro lives in Texas, and it has been seven years since I first met her.

"Since 2015, I was diagnosed with an anxiety disorder, initially mixed with depression, and later with 'Burnout Syndrome' (professional burnout, emotional exhaustion, burnout syndrome, work fatigue).
For several years, I sought various medical and therapeutic treatments for this condition, which greatly affects my daily life. I found Dr. Sandra, and her holistic approach has helped me tremendously." Rosa Robles, Colombia.
In early June 2018, I was diagnosed with cancer in my right breast. Unaware of the toxic effects of conventional treatments, I underwent a mastectomy, chemotherapy, and radiotherapy. It was then that I met Dr. Sandra Rangel, who introduced me to natural health methods and products to help mitigate the side effects of my treatment. With her expertise, Dr. Sandra formulated health supplements and personalized dietary changes to reduce the adverse effects of conventional chemotherapy.
Unlike many other patients I met during chemotherapy, my side effects were less severe, thanks to the supplements I was taking and the strict diet changes I followed diligently. Today, my medical check-ups show no signs of malignant cell reproduction.
I am deeply grateful to Dr. Sandra Rangel for her invaluable guidance and to God for orchestrating everything for my healing journey.
Lilia Espinoza, Colombia.
“At 36 years old, at the end of 2022, I was diagnosed with kidney cancer and the first thing I did was think of Dr. Sandra.
I met Sandra a few years ago in Miami, since we were working together, and she was the first person I thought of, so I looked her up immediately.
The program that Sandra offers is impressive, it made me see on a physical level what was happening, on an emotional level I thought everything was resolved and I realized that it wasn’t, on a mental and energetic level we also worked.
Something that I remember a lot in the first appointment that brought me a lot of calm was when Sandra told me not to ask why? Ask yourself why is this happening? What is the learning that you have to take from here?
At this moment I am completely healthy and during the treatment with Sandra I became pregnant, which was a longing in my heart and I had been looking for it to happen for a long time. I experienced many Miracles in the treatment and I am so grateful, the program I did with Sandra transformed me and my family and everyone around me.
This program was vital in all areas of my life. I honestly don't know what I would have done without Sandra."
Andrea Castellanos. Venezuela.
Pablo was diagnosed with pancreatic cancer in October 2021 and is completely healthy. “Dr. Sandra deserves all the credit here; she was a great support for us. I was very fortunate to have the support of Dr. Sandra who, with dietary changes, lifestyle changes, supplements, meditations and more helped my healing, I bless the Lord and I am very grateful to Dr. Sandra and also another person who has been a blessing and an impressive support is my wife, Tatiana.”
Tatiana: “It has been an adventure, the first person I called was a friend who went through cancer and she recommended that the first thing I had to do was to call to Dr. Sandra. That's what we did and we started to change many things, foods, kitchen utensils, lifestyle, supplements; Dr. Sandra was essential, instead of wasting time with other things or people, Sandra has all the knowledge and experience you need to recover from cancer. I received a new husband who is not only healthy but also a new human being.”
Pablo Espinel, Palm Beach, USA
