Welcome to MG Chiropractic, LLC

Call us at (206) 257-4022 today.

We proudly serve the chiropractic needs of patients in the Wallingford and Fremont neighborhoods of Seattle. We focus on giving the body what it needs to heal itself. That process starts with chiropractic care and ends with proper life changes. The life changes can be as simple as heel supports and as “complex” as nutritional support. At MG Chiropractic, we address all aspects of your health.

Chiropractic is a full-body form of healthcare that focuses on healthy joints and an unobstructed nervous system. Without healthy joints, we stop moving, and our bodies begin to break down. And without a properly functioning nervous system, our entire body begins to break down.

Objects in motion stay in motion, a philosophy reminding us that the longer we move, the longer we will continue to move. It’s also a philosophy that best summarizes Dr. Mason Greenslade’s goal to keep patients moving for as long as possible.

Meet the Chiropractor

  • Dr.
    Mason Greenslade

    When I was young, my mother was told I would never live past 21 years old. Conventional wisdom believed that I was stricken with Duchenne Muscular Dystrophy. Several tests, many of which were traumatic, showed symptoms supporting such diagnosis.

Reviews By Our Satisfied Clients

  • "The relief that comes with the unique adjustments Dr. Greenslade has given me is unexplainable. I am a professional dancer and need a lot of TLC for my body. He goes right to the problem every single time. No description of pain by me at all, and he goes straight to my problem area. I slept wrong on my neck one night and the next day without saying anything he went straight to my neck after evaluating my body and adjusted me there! I am always so impressed by his work! Thank you Dr. Greenslade, you have helped my body in so many ways."

  • "Dr. Greenslade is a great Chiropractor. I had no idea chiropractic care could cure a shoulder issue that I had for months. In 3 visits my shoulder was back to 100%.
    No cracking or twisting. A different, much gentler approach to Chiropractic care.
    Great experience.
    Highly recommended."
    Janis R. via Yelp
  • "Dr. Mason saw me when I was having neck spasms. Was in really bad shape -- saw him two straight days and the spasms stopped. Over the next few weeks I got curative treatments and learned exercises that have kept the neck problems away. I also loved that I didn't have to labor through forced cracking and popping! Loved the activator method!!!"

  • "I have been working with Dr. Greenslade for about 2 years. I first decided to meet with him since my shoulder was giving me issues in the gym, while lifting. He has completely fixed my shoulder, adjusted my posture and as an added benefit I am lifting heavier in the gym. He has kept me in tip top shape, and my recovery time has greatly improved. I recommend him to anyone in my gym, who is having issues with shoulders or while lifting."
