Dennis Kamau Wachira, popularly known as DJ Muller, is a father of two and a resident of Bungoma Town.A fan of nightlife, he became an avid party goer in his adult years. Over time, he succumbed to peer pressure and began using alcohol and hard drugs, including bhang and ‘lift’, a smokeless tobacco product considered even stronger than the widely abused Kuber.

He often went on drinking sprees with friend’s whenever he had money, a lifestyle that caused sleepless nights for his mother, wife and two children, who desperately tried to persuade him to change his ways.

Wachira worked as a sales attendant at a spare parts shop in Bungoma County during the day and moonlighted as a DJ in clubs across the county at night.

In August 2024, he started experiencing frequent mild headaches and occasional dizziness. That same month, he fainted three times while at work. Alarmed by his condition, his mother took him to one of the leading hospitals in Kimilili Town, where she disclosed his history of drug and substance abuse. 

After evaluation, the attending physician linked the fainting spells to withdrawal symptoms from addiction.  Wachira was prescribed medication and advised to attend regular counselling sessions to support his recovery journey.

Despite taking his medication and avoiding alcohol and hard drugs, Wachira’s condition worsened. The headaches became persistent and began to interfere with his work.

In early September of the same year, while delivering motorbike spare parts in Eldoret, he suddenly felt dizzy. On his way back to Kimilili, at Kipkaren, he began nose bleeding and eventually lost consciousness.

His family was notified immediately, and he was rushed to the hospital where he had been receiving counselling services. While attending to him, the doctor reprimanded him, suspecting he had relapsed into drug use—despite Wachira’s insistence that he had remained clean.

“The doctor insisted I was using drugs again, yet I had stopped for some time because I was on medication. I was given some painkillers, which I used for a while, and started to feel better,” says Wachira.

“I managed to return to work for the rest of September. Unfortunately, the cravings returned, and I relapsed into using bhang,” he admits.

In October 2024, his condition worsened. He began fainting repeatedly and decided to seek a second opinion at Dreamland Hospital in Kimilili. There, he asked the doctors to help him determine the cause of his frequent blackouts.

“I was advised to undergo a CT scan, which revealed a small lesion in my brain,” he recalls. The hospital informed him that his case was beyond their capacity and referred him to a neurosurgeon in Eldoret. A further review at the Tophill Brain and Spine Center in Eldoret confirmed that Wachira had a tumor in his head, though it could be managed without surgery.

Dr Florentius Koech, a neurosurgeon at the hospital, prescribed medication and discharged him to recover at home. After starting the treatment, Wachira’s symptoms eased. Feeling better, he resumed drinking and using drugs, returning to his party lifestyle.

“I felt completely fine after taking the medication. The headaches and dizziness disappeared, and I was able to work without any problems. At the time, I didn’t think my lifestyle was affecting me,” he explains.

In November and December 2024, he travelled and worked as a DJ at several events, indulging heavily in alcohol during the festive season. On December 28, he hired a car and travelled to Bungoma Town with three friends to plan an event. After receiving a down payment of Sh10,000, he treated his friends to drinks at a local club.

“While at the club, I met friends from Nairobi who were visiting the area. They joined us, and we partied together. During the fun, one of my friends from Kimilili got upset, feeling I had ignored him in favour of the others. I responded rudely, and in the heat of the moment, he struck me on the head—I lost consciousness,” Wachira recalls.

Wachira has no recollection of how he got home the next day—only that he woke up with a severe headache. His wife had travelled to her parents’ home with the children for the holidays. Feeling extremely ill and exhausted, he managed to text her about his condition.

“After that, I lost consciousness and only woke up the following day feeling even worse. I took some medication, but my situation kept deteriorating. I couldn’t move for three days because of the pain. My mother wanted to visit, but I hid from her—I didn’t want her to see me like that,” he recalls.

On January 1, his wife returned and found him in a terrible state. At around 7pm that evening, Wachira collapsed—and remained unconscious through the night and for the next three days.

His mother, Irene Wachira, initially assumed he had relapsed into drug use.

“I thought he was under the influence again,” she says. “But when I saw him, I knew it was something more. His body was cold, and he couldn’t stand. We rushed him to a local hospital, and the doctor told us, ‘If you wait past today, you’ll lose him.’”

Wachira was rushed to a hospital in Eldoret, where doctors had to resuscitate him before performing an emergency surgery. He had been struck on the head—directly where the tumor was located.

“Dennis arrived unconscious, showing clear signs of blunt force trauma to the head. A CT scan revealed intracranial bleeding and a ruptured tumor. It was critical—we had to operate immediately,” explained Dr Florentius Koech, the neurosurgeon who led the procedure.

Dr Koech and his team performed two life-saving surgeries: the first to remove the bleeding and crushed bone fragments, and the second to excise the tumor. Wachira was admitted to the Intensive Care Unit (ICU), where he was closely monitored.

“He was in a critical state, but he responded well after surgery,” said Dr Koech. “He regained consciousness and, remarkably, retained full memory—something quite rare in such cases.”

Wachira spent two weeks in the hospital recovering before he was discharged to continue his healing journey at home.

But what could have been a tragic ending became a powerful turning point.

This brush with death sparked a remarkable transformation in Wachira’s life. He has emerged from the darkness of substance abuse and serious illness with a renewed sense of purpose—and an unexpected discovery of creative talents that are now shaping his new beginning.

But the most astonishing part of Dennis’ recovery wasn’t just medical, it was personal. After surgery, Dennis began to notice an unexpected change: new creative abilities he had never tapped into before.

“I started singing,” he said. “I discovered auto-tune software and began recording my own music. I also got into scripting, designing, and beat-making. These were things I never imagined doing before. It was like the surgery unlocked something inside me.”

His mother, Irene, is now a happy mother after his only son changed his life “My son had used all kinds of drugs. We had almost given up. He is now a different person.”

Now, fully sober, Dennis says he can finally see the value of life and his money. “Before, everything went to drugs and alcohol. Now I’m focused. I’m working on my music, designing clothes, and even producing beats. It’s like I was given a new brain and with it, a new chance.”

According to Dr Koech, Wachira had been diagnosed with a low-grade astrocytoma—a type of brain tumor that initially did not require surgical intervention. Instead, it was being closely monitored, with symptoms managed medically until the injury that triggered the emergency.

“Low-grade astrocytomas typically don’t require surgery unless they begin to grow significantly over time,” Dr. Koech explains. “The standard approach is regular monitoring through annual scans. In Wachira’s case, he had one of the three rare forms of astrocytoma, which is generally non-progressive.”

He notes that symptoms vary depending on the tumor’s size and location. Common signs include persistent headaches, seizures, fainting, and weakness on one side of the body.

“A doctor can often determine the tumor’s location based on the side of the body affected,” he adds. “For instance, weakness on the right side suggests the tumor is on the left side of the brain. If the tumor is located at the front of the brain, it may impair cognitive functions such as reasoning, problem-solving, and even affect vision.”

What made Wachira’s case exceptional, Dr Koech says, was the traumatic injury that caused the tumor to rupture.

“He was admitted with a Glasgow Coma Scale score of 4 out of 15—which is dangerously low and indicated he was on the verge of death,” says Dr Koech. “But he made an extraordinary recovery. Within a week of surgery, he was talking and had regained full memory.”

Wachira continues to visit the hospital for follow-up reviews to monitor his recovery and overall health.
