Meet Dr. David Glazer, Founder of Function4Life
Back pain isn’t just an inconvenience. It can steal your time, your energy, and your ability to fully enjoy everyday life.
For example, something as simple as lifting your child, finishing a workout, or getting through your workday can become frustrating when pain keeps coming back.
That’s why Dr. Glazer takes a different approach.
Unlike traditional chiropractic care or cookie-cutter physical therapy programs, his treatment focuses on functional, movement-based solutions tailored to your body and lifestyle.
Every plan is one-on-one and personalized. Most importantly, the goal is to address the root cause of pain, not just the symptoms.
As a result, patients can move better, stay active, and prevent the same issues from returning.
Before becoming a chiropractor, Dr. Glazer worked professionally as a Nationally Certified Massage Therapist after earning a Bachelor’s Degree in Allied Health Sciences from Bridgewater College.
He later completed advanced education including:
Doctorate of Chiropractic
Bachelor’s Degree in Life Sciences
Master’s Degree in Sports Science & Rehabilitation
Today, he combines over 10 years of clinical experience with a deep understanding of movement, rehabilitation, and athletic performance.

How our treatment differs from traditional chiropractic care or physical therapy
If you are searching for a long-term solution that keeps you active, strong, and pain-free, this section will help you understand exactly how Function 4 Life can support you.
1. What makes Dr. Glazer’s approach different from traditional chiropractic or physical therapy?
Function 4 Life focuses on functional movement and long-term performance, not just temporary pain relief.
Instead of quick adjustments or generic exercise sheets, every patient receives a customized treatment plan built around their goals, lifestyle, and activity level.
First, Dr. Glazer performs a detailed movement assessment.
Next, he identifies the root cause of the issue.
Then, he creates a plan that improves strength, mobility, and stability.
As a result, patients can recover faster and reduce the risk of future pain.
2. What types of conditions do you treat?
The clinic commonly treats back pain, low back stiffness, pelvic and hip discomfort, muscle soreness, and movement related injuries. Care often includes exercise therapy, stretching, lower back strengthening, and guided progressions back to workouts, running, or daily activities.
3. Do you offer prenatal and postpartum chiropractic care?
Yes. Dr. Glazer provides prenatal care to help reduce pregnancy related back and pelvic discomfort while keeping mothers active safely. Postpartum care focuses on recovery after delivery, addressing core weakness, hip pain, and helping women return to exercise with confidence.
4. Do you work with athletes?
Absolutely. Dr. Glazer works with runners from 5Ks to ultramarathons and supports athletes at the high school and collegiate level. He provides injury rehabilitation, prevention strategies, and performance guidance so athletes can continue training without unnecessary setbacks.
5. Is this practice only for athletes?
Not at all. While many patients are active adults, care is designed for anyone who wants to move better and feel stronger. Whether your goal is staying active with your kids, returning to the gym, or simply getting through the workday without pain, your plan is tailored to you.
6. What credentials and certifications does Dr. Glazer hold?
Dr. Glazer is a BirthFit Professional and Coach, a Credentialed McKenzie Practitioner and Mechanical Pain Specialist, an Elite Provider for Active Release Techniques, a Certified Kinesio Taping Practitioner, a Functional Movement Screen Specialist, a Level 1 CrossFit Trainer, a Level 1 Sports Performance Coach through USA Weightlifting, and a Deep Tissue Therapeutic Laser Therapy Practitioner.

“I went to Dr. Glazer during my second and third trimester of pregnancy. Because of his chiropractic care, I remained comfortable through the last day of my pregnancy. I began seeing him for some lower back discomfort. After one visit, it was gone! I highly recommend Dr. Glazer for anyone who is expecting to prevent pregnancy aches and pains.”
“Thoughtful, intelligent practitioner who has helped me tremendously.”
“Coming here was one of the best things I ever did!”
“One of the best parts of your treatment plan was to allow my training to continue… I had to scale back my mileage, but I wasn’t grounded. Just working smarter and incorporating dedicated exercises and focused stretching/strengthening… and tweaking as I came in with a new complaint each time. You rock!”
