TLDR - the most caring, thorough, knowledgeable , and honest doctor to see if you’re experiencing back pain. 5 stars. Would give 6 if I could. 37m, herniated disc Oct ‘22 in the gym with heavy weights and bad form causing severe sciatica and pain. Nightmare pain I saw 15~ doctors over a 9mo timeline trying to get a definitive game plan to get my life back. Not one was as interested or thorough as Dr. Jim. Using Stu McGills framework (but adding his own expertise being an MD), I left with an affirmative game-plan and confidence that I finally had someone in my corner. He taught me a ton, including some “red flag” symptoms that I was experiencing, that other doctors hadn’t mentioned. Cannot put a price tag on that type of care and attention to detail. As if I didn’t think my first few hours couldn’t be more impressed with Dr. Jim, he ended up giving me a call on Sunday to follow up from an ER visit and check how I was doing. Truly cared about my well being. If you are experiencing pain and on the fence about seeing Dr. Jim and Maria, I would recommend them 100 times out of 100. Truly a guiding light.

Dr. Jim was my saving grace throughout CIRS recovery for my son and myself. He listened to all of my concerns and was very caring to both my son and myself. Under his care, both of us are feeling so much better than we were before. His office is very clean and his staff is friendly and professional. I hope we never need him again, but if we end up mold sick again, he will be our first stop. Thank you Dr. Jim!

Having Dr. Jim and his staff helping me through my injury and the most difficult time in my life has been a blessing. He truly cares about you as a person and wants to do his very best to provide you with the care that you deserve. The appointments are not rushed and he's extremely thorough when treating you. Without Dr. Jim I would be much worse off, so I'm very grateful to have found such a knowledgeable and caring doctor. I have the utmost respect for Dr. Jim.

It has been 10 months since I visited doctor Jim and my back pain has reduced about 70% as long as I continue to do the recommended exercises and walking, Things seem to be working out well. Now just trying to get rid of my morning back pain is the next task. So maybe a new mattress is next on the list. I've been an auto mechanic for over 50 years and I thought there was no help for my back after seeing about a dozen doctors but I guess there is hope with the McGill method.

I highly recommend Dr. Lysander Jim who helped me significantly from CIRS and mold illness. Nothing else took away the pain until I was on his protocol. He is understanding and patient. Go see him!

He was good with figuring out that my house was making me mold sick. A year later I am still sick but I’ve had breast implant illness as well as CIRS from mold exposure. I’m only 30 percent into the shoemaker protocol. Some days are better than others. Hope to make a full recovery very very soon.

Dr. Jim was the 9th medical professional I consulted with for chronic, debilitating back pain. I had been diagnosed with lumbar disc disease and was offered surgery and pain medication but wanted to try physical rehab first. I dedicated myself to traditional PT, but made little to no progress. I was confused, frustrated and heading towards deep depression. I saw Dr. Jim when I discovered that he has studied Dr. Stuart McGill's mechanical approach to fixing back pain. We worked together on a weekly basis for 6-7 months to address my spine issues. Dr. Jim became deeply invested in my case; he checked in with me often and spent many hours outside of my scheduled appointments poring over my many MRI images and reports. It was Dr. Jim that recommended I consult with a specialist to further investigate several cysts in my sacrum before having disc surgery. Had I not seen Dr. Jim, it is likely that I would have had the wrong surgery for my particular issue. I highly recommend Dr. Jim!

Dr Jim is the first and only doctor to truly take the time to properly diagnose me for mold disease. I have been seeing Dr Jim for over one year and every supplement and medication was prescribed after careful testing and attention to every detail. I could not recommend him enough to anyone suffering from mold / CIRS. My healing has been remarkable over the past year and a half of his treatment. Yet as all mold illness goes, I recently had a flare up of symptoms so severe I felt the ER (during a pandemic) was the next necessary step, to make sure nothing life altering was going on. Dr Jim not only called several times to check in on me, but kept his phone on him all evening to be texted updates. I have never had a medical care professional give my mysterious illness such proper care and expert attention. Thank you Dr Jim for being such an outlier in the medical field.
