About Us

Tired of constant
Back Pain?

There’s nothing like severe back pain, regardless of the cause, to railroad your life! We believe in the least traumatic treatment that will give you the best outcome. We offer in-office spinal injections as well as minimally invasive procedures. We even have in-office rehabilitation services.


Afraid of a
Long Recovery?

Surgical alternatives to solve back pain don’t always have to involve a prolonged and debilitating recovery. We specialize in solutions that offer you “big surgery, small incision, short stay.”  Among the procedures we perform are endoscopic discectomy and motion sparing total artificial disc replacement.

Our Specialty is the Patient with Spinal Pain

Drs. Diezte and Logan specialize in care for all areas of the spine related to injury, illness, sports-related issues, and congenital conditions.

Progressive developments in minimally-invasive spinal surgery, including endoscopic assisted decompression, percutaneous spinal fusion and adult scoliosis surgical correction, have greatly increased successful outcomes while decreasing recovery times.  Some procedures allow patients to be up for dinner and walking back into their own homes by the next day.

Also, greater use of motion sparing spinal surgery, especially cervical and lumbar artificial disc replacement, helps avoid spinal fusion and make for better treatment, better results and happier patients.  Big surgery, small incision, short stay,” has become a reality with the goal of preventing the need for future surgeries.

I am very impressed with Dr. Logan! His correct, accurate diagnoses and immediate corrective action saved the life of my family member. He not only performed in the highest professional standards, but showed a personal care, comfort, and concern to family members. I would highly recommend Dr. Logan to anyone needing his specialized skills.

I wouldn't see anyone but Dr. Logan and his staff.
Excellent doctor and experience.

Dr. Dietze, I remain in your debt! Because of you, I can live life again, pain free! Thank you from the bottom of my heart! My family thanks you!

AMAZING NEUROSURGEON! Dr. Dietze performed a cervical implant with a 1-stage fusion AND a lumbar implant with a 2-stage implant. He has the BEST bed-side manor! I wouldn't trust my back problems with any other doctor!
