An Engineer's Precision, a Patient's Perspective: Meet Dr. Daniel Mok

Dr. Daniel Mok, a board-certified, fellowship-trained Doctor of Osteopathic Medicine (DO), brings a background in medical device engineering, a personal understanding of chronic pain, and advanced training in interventional pain medicine, which treats pain with targeted, minimally invasive procedures, to patients at Barrington Orthopedic Specialists.
Before he ever treated a patient, Dr. Daniel Mok spent his days designing medical devices. As an engineer, he found real satisfaction in building technology that could make life better for the people who used it. Over time, though, he realized he wanted something more personal: to sit across from patients, learn their goals, and shape their care around them.
That desire, along with his own experience living with chronic pain, set him on a path to medicine and, eventually, to Barrington Orthopedic Specialists, where he now helps patients find relief from pain in the neck, back, spine, and joints.
From Designing Devices to Caring for Patients
Dr. Mok earned both his bachelor's and master's degrees in mechanical engineering from the University of Louisville. His move into medicine grew out of the same passion that drove his engineering work: using technology to improve people's lives. Medicine let him take that passion a step further by working directly with patients and tailoring treatment to each person's needs.
His own experience with chronic pain shaped that path in a lasting way. Living through it gave him a firsthand sense of how pain affects daily life, and it strengthened his commitment to helping others in the same situation. After earning his medical degree from the DeBusk College of Osteopathic Medicine, he completed a residency (hands-on specialty training after medical school) in physical medicine and rehabilitation at the University of Kansas Medical Center, followed by fellowship training (an extra year or more of focused training in one area) in pain medicine at Washington University in St. Louis. Pain medicine became the place where his interests in rehabilitation, procedures, and technology came together, all in service of helping patients return to the activities they care about most.
'After experiencing chronic pain myself, I gained a much better understanding of what patients go through and developed a strong desire to help others facing similar challenges.'
Why Spinal Cord Stimulation Stands Out
Dr. Mok offers a range of minimally invasive treatments, including epidural steroid and facet joint injections and radiofrequency ablation, a procedure that uses heat to quiet irritated nerves that send pain signals. Among these options, spinal cord stimulation holds a special place for him. Spinal cord stimulation (SCS) uses a small implanted device that sends mild electrical signals to the spinal cord to change how pain signals reach the brain. For Dr. Mok, the appeal started with the technical side: the chance to work with cutting-edge technology in a way that makes a meaningful difference for patients.
What keeps him invested is what he sees it do. For people who have lived with chronic pain for years, spinal cord stimulation can sometimes bring relief and the freedom to return to activities they have not been able to enjoy in a long time.
Taking a Fresh Look at Difficult Cases
Some of the patients Dr. Mok sees have lived with pain for years, often after multiple surgeries and treatments that did not bring the relief they hoped for. By the time they arrive at his office, many feel frustrated and worry they have run out of options. Dr. Mok understands that frustration, and he believes the right response is patience, careful listening, and a willingness to keep searching for ways to improve their quality of life.
'I think these patients deserve someone who is willing to listen, take a fresh look at their situation, and keep looking for ways to improve their quality of life.'
What to Expect From a Spinal Cord Stimulation Trial
One of the advantages of spinal cord stimulation is that patients can try it before committing to it. The process starts with a trial, an outpatient procedure where you go home the same day. Over the following several days, patients get to see for themselves whether the device makes a real difference in their pain and daily routine.
If the trial goes well and a patient decides to move forward, the permanent implant is placed at the Schaumburg Surgery Center in a similar way. Patients can also expect to go home the same day after that procedure.
An Engineer's Eye in the Operating Room
Dr. Mok's engineering background is unusual among pain physicians, and it shapes how he practices. He has always been curious about how things work and how small details affect the final result. That mindset helps him understand the technical differences between the devices he uses and how those differences can influence which option fits each patient best. In the operating room, it shows up as a focus on precision, careful planning, and a deep understanding of the technology involved.
That curiosity extends to research. Dr. Mok has studied why some patients do not respond to spinal cord stimulation, as well as nerve ablation for knee pain before and after knee replacement. His work earned a Best of Meeting Award at the American Society of Regional Anesthesia and Pain Medicine's annual pain medicine meeting. What excites him most about the field is that it keeps moving forward. Better technology and a growing understanding of which treatments help which patients mean new options for people who may not have had them before.
Why He Chose Barrington Orthopedic Specialists
After completing his fellowship, Dr. Mok was looking for a practice where he could put down roots and become a long-term part of the community. Conversations with the group at Barrington Orthopedic Specialists showed him exactly that kind of place. With more than 45 years of caring for the Chicago area, the practice offered the chance to build lasting relationships with patients and see multiple generations of the same family come through the doors, something he has already witnessed firsthand.
He also values the team around him. Barrington Orthopedic Specialists brings together a diverse group of orthopedic surgeons, rehabilitation physicians, and foot and ankle specialists, each with their own areas of expertise and a shared commitment to their patients. When a patient has a question outside his specialty, Dr. Mok knows he can turn to colleagues he trusts, so every patient gets the right care from the right person.
Helping Patients Get Back to What Matters
For Dr. Mok, success is measured in what patients can do again. A patient picking up their grandchildren, getting back into the garden, or returning to an activity they had given up years ago is what makes the work meaningful to him.
'I'm really in the business of improving function and helping people get back to the things that matter to them.'
Advice for Patients Feeling Nervous
Dr. Mok knows that any procedure can feel intimidating. He reassures patients that spinal cord stimulation trials are very similar to many of the other procedures he performs, and that his team takes care to keep patients comfortable and relaxed from start to finish. Most of all, he encourages patients to bring their questions to him directly.
'The best advice I can give is to sit down with me and talk through any concerns you may have so I can walk you through the procedure and make sure you know what to expect.'
Outside the Office
When he is not caring for patients, Dr. Mok loves to travel and experience new cultures and foods. He is an avid runner, rock climber, and hiker who enjoys the challenge of reaching the summit of a new mountain. Lately, he has been spending more time with his family and exploring the area around their new home. And for a fun fact: he once rang in the New Year in Times Square, an experience he calls exciting to do once, though he is not sure he would want to repeat it every year.
Find Relief Close to Home
If chronic pain has been holding you back, a fresh perspective may be the next step. Dr. Mok sees patients at the Barrington Orthopedic Specialists offices in Schaumburg, Buffalo Grove, and Elk Grove Village, and he is ready to listen, explain your options, and help you work toward getting back to the things you love.
