Alexander P. Hersel, M.D.

PMIR Medical Center Founder
Pain Management Specialist


Who Is Who


In medical school, we weren’t given major educational experience in dealing with chronic pain. In my anesthesiology residency, I began to truly understand what a patient’s pain points were. Today, I spend a lot of time with my patients to understand the source of their pain, and I use both Western and alternative therapies to help ease it. When you walk in my office, I truly want the best for you. I don’t settle for mild success but believe in the completion of what we started together.

My wife read about a seminar on pain management at Pharmaca drug store. We attended along with about a dozen other people. Dr. Hersel presented a one hour program on the various conditions that can cause back pain, the cycle of persistent pain and the remedies available. We were both impressed with Dr. Hersel’s demeanor and level of expertise. This being my first exposure to a pain management practitioner in this area, I researched other providers and ultimately narrowed the choice to two, Dr. Hersel and one other. The other provider does not accept medicare patients. I made an appointment with Dr. Hersel for my low back pain. The imaging center is right across from the office so getting the mri and xrays was very convenient. At the consultation appointment Dr. Hersel explained in detail the imaging results and proposed a treatment consisting of two epidural injections two weeks apart. The next week I appeared for the procedure at the surgery center with a locked neck. I hadn’t slept in a bed for two nights and there was no position I could find that was not painful. Although this was not a part of the proposed treatment, Dr. Hersel was very concerned and compassionate. During the preparation for the epidural, Dr. Hersel arranged for the needed mri for my neck for that day and had a prescription for pain medication ready for me when I left. I also had an appointment by phone within a day for a cervical epidural the next week. The pain medication got me through the mri and allowed me to sleep in bed. I’ve just received the cervical epidural and am extremely pleased with the results. I am so happy to have found Dr. Hersel and his staff at the PMIR clinic. Every interaction has been extremely positive, even when I complicated the treatment flow with my locked neck. Many practitioners would have treated the “chief complaint” and not addressed the neck problem at that time. There has been no problem with insurance, either. My experience has been entirely positive and Dr. Hersel and his staff have exceeded all expectations.

I cannot begin to express my gratitude to Dr. Hersel, or lavish enough praise for one of the finest doctors I have ever come across. A nightmarish odyssey with a difficult cervical spine fusion was so debilitating it left me unable to work or function normally. As a result I tried a variety of treatments, saw numerous doctors and was on a tremendous amount of pain medication. I ultimately had a spinal cord stimulator implanted by another doctor who, to put it mildly, made the initial problem far worse. At that point I was in total despair and frankly did not know where to turn. I feel completely blessed to have found Dr. Hersel, and while it may sound corny, he honestly turned my life around. Dr. Hersel did a repair and revision of the spinal cord stimulator and due to his expertise and skilled surgical skills I was able to get the pain relief initially promised as a benefit of the stimulator.
Dr. Hersel is progressive and clearly up on current innovations within his field, however, I would describe him as a bit of a throw back to old fashioned medical practitioners when it comes to taking time to truly get to know his patients. He is so caring, treating the whole person rather than just the site of the pain, and earnestly appears to take pride in helping his patients. In short, he is the ideal when I think of “bedside manner.” I truly feel fortunate to have found Dr. Hersel and the entire PMIR staff. The office is pristine and well run by an extremely friendly and helpful staff. It is my pleasure to wholeheartedly recommend this phenomenal doctor and superior medical practice.

I have been a patient of Dr. Hersel for more than 5 years. During that time, Dr. Hersel has been one of the most gracious, understanding, and patient doctors I have ever had the pleasure of knowing. He has worked very hard to determine the precise source of my chronic back pain and diligently sought to relieve it. Dr. Hersel’s apparent level of knowledge and expertise regarding my significant back situation is beyond reproach. He really makes you, the patient, feel like he cares about you and wants to help you and does in fact help. I suffer from chronic lower back pain that is, at times, unbearable from a motor vehicle accident. Ive been through several procedures over the years. After each one, I’ve found significant relief. I have a pinched nerve and issues with disks in my lower back and neck. I will forever be grateful for Dr. Hersel and the other doctors at PMIR. You’re truly are a wonderful doctor and person. Thank you so much Dr. Hersel for your continued help and kindness.

-Geena Bigelow, Ventura, CA

I want to thank Dr. Hersel for spending these past years working with me to alleviate my pain. Because of the caring ways he has shown me, and my back, he was able to determine that I needed surgery for pinched nerves. He will work to find out how he can relieve your pain. Not just a great doctor, but a wonderful humanitarian — love in his heart, and a smile on his face for all that seek his help. From the bottom of my heart, thank you Dr. Hersel and everyone at the surgery center for everything you have done for me.

-Susan Anderson

Dr. Hersel is the best doctor I’ve ever had — so compassionate and caring. He is the only doctor that has not only given me relief from my severe injuries, but has corrected and helped to improve my way of life. I love him, he is the best doctor in the world! He listens to what my problems are, and we resolve them together! He also cares about me. He makes an effort to communicate and keep in touch with my other doctors to make sure I’m getting the best healthcare I could possibly get!

-Jennifer White

Dr. Hersel answered my questions thoroughly. He was very pleasant and inquiring. He was very explicit and I really like him. Everyone in the office makes sure everything goes right for me and is unusually pleasant.

-Lois Taylor

I had my first appointment with Dr. Hersel and I was so impressed with his level of caring. He was very empathetic about my pain problems, and he has set a treatment plan into place. I may have found my hope. The support staff are all pleasant and accommodating.

-Renee, Thousand Oaks, CA

Dr. Hersel is the most compassionate doctor I have ever seen. I have chronic back pain and I endured two unsuccessful back surgeries befor I saw him for the first time. Dr. Hersel made me feel that he was as happy to see me as I was to see him. His front office staff is very professional and the nurses in the surgical suite are top rate. I cannot say enough about Dr. Hersel and the way he runs his practice. YOU’RE THE BEST!

-Cindy Pasco

Dr. Hersel,

You continue to exceed my expectations as a physician and as a humanitarian. Thank you for taking the time to listen to my situation and empathize with me. It’s amazing that I am holding it together with what I’ve been through this past year: the bi-lateral pneumonia, the chronic body (mostly back) pain, and now this second back surgery. This has brought an enormous amount of stress upon me and my family with also having the responsibility of an infant. This year has drained me, physically, emotionally and financially. But I just want to thank you for being you. There are a lot of people out there who practice medicine for the monetary benefits, not because they truly care about their patients. Though I’m sure you are compensated well (as you should be), you definitely strike me as one that cares for your patients’ well-being and I commend you for that. You are one of a kind and I couldn’t be more proud to say to people when they are in search of help with their own physical troubles, that “Dr. Alexander Hersel is my doctor.” I thank you again for your time and understanding today. God bless you and your family. I wish you and yours many years of good health and happiness. Be well…
