Dr. von Merveldt-Guevara Stepped In And Literally Saved My Son’s Life

“In May 2016, my (just turned) 1 year old son went into crisis. He had seizures every few minutes and was consequently diagnosed with Clonic-Tonic seizures, that no anti-epileptic drug would help. Thankfully, Dr. von Merveldt-Guevara stepped in and literally saved my son’s life.
Xavier had been seizing for over 3 days, when Karen told me to get magnesium and give the specific amount to him in his bottle, while we were waiting for the hair analysis results. We gave Xavier the magnesium for just over 12 hours, when the seizures stopped. It was a life saving breakthrough. Karen tweaked his mineral dosages according to his hair analysis, and continues to do so, as he grows and thrives.
Karen saved Xavier’s life. To this day, Seizure Specialists and Pediatric Neurologists are amazed at Xavier’s excellent health, and praise Karen for her work. A slight speech delay, that is being resolved through speech therapy, is the only lasting effects of his life-threatening Tonic-Clonic seizures. Thanks to Karen and her tireless work to keep Xavier in optimal health, he has not seized since that event.  Karen is diligent, careful, dedicated, and kind, and I can’t imagine anyone else being as incredible as Karen was, especially throughout such a difficult situation.
Thank you for saving Xavier, Karen.  I owe you more then I can ever repay. Many hugs and thanks,”
Xavier’s Mom – VA

You Have Healed My Life More Then I Could Have Ever Imagined

“When I met Dr Von Merveldt-Guevara, I was the sickest I had ever been in my life. And that’s saying a lot, since I had been ill since I was 10 years old. Right before I met Karen, my son and I barely made it through the pregnancy, and I was exhausted, overweight (even with strict dieting and exercise), had swollen joints, migrating pains, and terrible blood lab results.
My body wasn’t functioning correctly: insulin resistance, high blood pressure, high blood sugars, extremely high cholesterol, poor circulation, hypothyroid, and the list goes on.
Then, I met Karen. After doing a hair analysis, Karen set me on the path to excellent health. Karen was so kind, understanding, and took the time to help me understand the mineral balancing process. She answered my emails and calls, (even text messages), very quickly and made me feel supported through one of the most monumental health shifts I have ever experienced. All of my diagnoses have been reversed, in less then a year doing the minerals.
Karen, thank you for taking the time and energy to help me be well, you have healed my life more then I could have ever imagined! Much love,”

Give My Baby the Best Start Possible

“Thank you Karen for this wonderful session! Being a counselor and healer myself, I am a very critical person and do not give myself easily into another person’s hands. But when I found out I was pregnant, I wanted to give my baby the best start possible and release as much patterns and old blockages as I could reach. As I teach emotional release work myself, I felt as if I already had released quite a bit.

Nevertheless I feel so much better after this session! With her intuitive acupressure Karen and her spirit helpers release blocks on the cellular level and it feels really good to get those “buttons pushed”. She put my body through a range of movements and motions and I clearly felt that my spine aligned and I “straightened out” on more levels than one.

On some areas, like my ankles, she worked relentlessly for quite a while and I must say that I was surprised about the many pictures I saw (some of them from “past-lives”), which were stored in there.

You don’t have to be a psychic or clairvoyant to experience a wide range of picturesque scenarios in your inner realm. There is no place for thinking as the emotions take over through the motion movement of the body. You feel like you rather watch the process than you participate in it. The more you let go, the deeper the spirits and Karen can work on you and the more good can happen for you.

Allow yourself this session of physical and emotional support, so that you can peel away the denser layers off your spiritual true self and radiate more of who you really are!”

Woken Up to Reality

“Waking up to reality” – After living in all kinds of separate realities all my life, having been highly dissociative with a lot of mental struggle, diagnosed by the age of 12 with Borderline Personality Disorder and later other diagnosis like schizoid, dissociative, ADHD, obsessive-compulsive, depression, eating disorders, etc., I have now woken up to reality (without the need to fight it anymore).

What happened within the sessions? I do not really know. What I do know is, that something happened. It feels as if layers of clouds got pulled away, so the sun of reality could eventually shine through clearly. It feels like giving birth to myself, incarnate and land at the same time. Land in a world of grounding and love for what is.

What I have experienced after the sessions is, that something definitely has shifted, with a newborn ability to discern what is real and what is not, and on which level. Projections show themselves clearly in the mirror and illusions fall dead to the ground.

It is the most ego-less, therapeutic experience I have ever had. Thank You!”

True Inner Self

“First of all: A thousand Thank Yous!!! You cannot describe with words and express, what happens in these sessions with Karen. Guided and in touch with my True Inner Self, I was able to dive into the deepest depth held and protected, to realize “more and more” of my Self. Every single one of Karen’s sessions is an incredibly enriching experience.”

Relief from Migraines

“To those seeking a new approach to healing:

This letter is to express my heartfelt thanks to Karen Merveldt-Guevara. I found Karen at a very low point in my life. At the time I was suffering from headaches nearly everyday. To say I was desperate would be an understatement.

Before I went to Karen, I’d gone the usual route by seeing physicians who would prescribe pills that didn’t work or would tell me I was stressed out. I even went as far as having a CAT scan, which showed nothing significant. Some of my migraines were so severe they put me out of commission for days.

When I met Karen she explained that she used a hands on healing technique that I had never heard of before. It sounded a bit far-out, but I needed to get my life back. Karen worked on me for (two) hours, and I really felt an amazing energy come from her. Almost four weeks later, my headaches seem to have gone. I don’t feel a need for any medication, not even an aspirin. There hasn’t been a western-trained doctor that has come close to giving me relief.

I also had a broken arm that was slow in healing. I was told I would not get my range of motion back. I was unable to bend it and completely straighten it out. My arm, which I never thought would get better has gotten much better!

Another thing that I have noticed about feeling better is that I have a lot more energy, and don’t get into any more dark moods. Being physically healthy helps heal you spiritually as well. I never dreamed that I could feel so much better. I kept praying for miracles, now I know they are possible.

I would recommend Karen Merveldt-Guevara to anyone who is in need of healing. Her techniques for physical and emotional healing work far surpass anything I’ve been through. I’ve been blessed to find her, and truly believe she can help those looking for answers.

Birth to Myself

“Thank you for this profound experience. This kind of treatment can only be done with complete devotion. Your being fully present gave me the chance to let go off myself entirely and to feel safe. I wish to say thank you, too, for liberating my pain, my feelings, my thoughts, and draining them through yourself. I had the feeling to go through my own birth, together with a lot of pain and grief. You breathed with me, and you held and guided me. I had never come that far all by myself. In the end of the treatment I gave birth to myself, anew, and the first time in my life I had the feeling: I’m allowed to live!! Simple as that!! Simply based on the gift to be born.”

Tribal Woman

“Karen embodies the “tribal woman” in her work as a healer and inspiration for all women as we search to reclaim our femininity and health on many levels.

104 Degree Temperature

“To the doubting Thomases and disbelievers: When you walk into a Doctor’s office and you don’t get better, and he has had six shots at it and you‘ve tried antibiotics, homeopathics and vitamin C…You walk in at Karen’s with 104˚F temperature after two weeks and it’s gone to normal after a session of one hour and a half and it stays that way, then you’ll experience, what I have.”

Gary Remes, Massage Therapist, Specialized in Neurofascial Reeducation, Longmont, CO

Ceremonial Healing Treatment

“…It is difficult to find a word that describes this kind of healing session. I’d almost like to call it a “ceremonial healing treatment”. The reason for which I went to see Karen was curiosity, interest and most of all my almost chronic back pain.
With her assistance I was able to go on the journey into my subconscious, a journey to my Self.
A path on which you can stumble over rocks and take them out of the way, a path on which repressed memories become conscious again, a path on which you will reach your Self through your body.
If you are ready to let yourself go with your body and your soul, and you can allow, that somebody else takes over the communication between you and your Self, you can launch a process as interesting and multilayered, opening, rich in experience and fascinating as can be.
My overall energy balance increased after the session, a pleasant and relaxing treat for body and soul. My back pain disappeared permanently in consequence!”

Holistic Diagnosis and Treatment Skills for Complex Health Problems

“I am grateful to Karen von Merveldt-Guevara, in Sedona, for helping me get through several health challenges and back to wellness. She has a unique blend of healing resources, including medical training and credentials (built on her rigorous M.D. from Germany), holistic diagnosis and treatment skills (addressing the mind and spirit, as related to the body), and an intuitive ability for insights and creativity (which seems to elude conventional health practitioners). She has amazed and comforted me with her rapid, consistent and on-target handling of my often obscure and complex health problems over several years. Unlike the heal-and-leave, and narrow-focused professionals, I have been to, she, typically in collaboration with other healing allies, has helped me regain my wellness and provided me with effective health regimens for maintenance. I am a much healthier and happier person because of Karen’s medical competency and health wisdom.”

Larry J. Rosenberg, Ph.D, retired marketing professor and management consultant, Sedona, AZ
