    Wonderful provider with kind demeanor who listens to me and answers questions.

  • Sep 18, 2019

    Very good. Very professional. Excellent care. Dr.Chahin and staff were GREAT.

  • Sep 18, 2019

    Dr. Chahin has and continues to provide treatment and evaluations of my health condition that far exceed any I’ve had in the past years.. Dr Chahin does not just evaluate my muscular disorder but he asks, takes the time needed to listen how I am doing and managing day to day. It is so reassuring how Dr Chain remembers me and sincerely cares about my life challenges and progress, his sincere compassion never waivers and with encouragement and further testing when needed throughout the years... Dr Chain has found underlying conditions as they appear and when needed provided further treatment or referred me to my PCP or other provider if needed. It still amazes me how Dr Chahin’s exceptional skills in Neuromuscular with all its complex and unique to each patient variations is addressed with sincere and professional attention to assist me in progressing and living and having the best life I can with this Neuromuscular condition. I wish every provider was like Dr Chahin with his passion and overall knowledge that has continually helped me to live the best I can with this Neuromuscular condition ... his respect for my questions and how he addresses and provides treatment or support is evident in how I continue to live .. Dr Chahin’s exceptional knowledge and passion to apply his skills is not only professional but reassures me that he cares and wants what is best for me ... I am so glad that OHSU Neuromuscular Clinic was able to recruit and keep him. Thank you

    Dr. always friendly and caring

  • Sep 04, 2019

    I can tell Dr. Chahin has my best interest in my medical care and treatment. He is a good listener and I look for this in medical professionals

  • Sep 03, 2019

    I'm very impressed with Dr. Chahin's knowledge in his medical field of expertise. He's been fantastic for me and I would definitely tell anyone that has these kind of problems that you know to try to see him.

  • Apr 30, 2019

    He was great to work with and answered our questions in a calm and clear manner. My problem is new to us and we had lots of questions. Everyone was nice, calm and totally helpful.

  • Apr 27, 2019

    I have seen many other neurologists through the years who were unable to diagnosis my muscle disease. Dr Chahin did give me a confirmed diagnosis and has prescribed treatment for this disease. He also ordered related cardiac tests. He has been very thorough and competent in his care. He is kind and compassionate, and an excellent doctor. He answered all of my questions, and explains things well. He also informed me of clinical trials of gene replacement therapy that will be happening in the next few years that would enhance the treatment this disease. I have recommended Dr Chahin to a friend, and would highly recommend him to others.

  • Apr 27, 2019

    Dr Chahin is knowledgeable, caring, and good at explaining one’s disease and what options are available for treatment. I would highly recommend him to anyone suffering myositis diseases. I appreciate his enthusiasm with a patient when all is going well too!

  • Apr 24, 2019

    Dr. Nizar Chahin is the most knowledgeable and genuinely compassionate physician I have known through the course of my neurolomuscular disorder. I have seen the most progress in my condition while under the care of Dr. Chahin. I feel like a person vs a patient with a condition that Dr. Chahin is treating, he really is genuinely caring about the ways my neuromuscular condition affects my life and always listens and answers questions.

    Dr Chahin is wonderful. His desire to help amazes me and his attitude is always positive. In my opinion, he is the best. And staff is always accommodating and helpful.

  • Apr 03, 2019

    Drs very positive and encouraging, take time to listen and explain.

  • Apr 02, 2019

    I am so very thankful for the Myositis Clinic. To be able to discus my health with two brilliant specialists, Dr Chahin (Neurology) and Dr Ghetie (Rheumatology) leaves me feeling protected, cared for, blessed.

  • Mar 15, 2019

    This providers been wonderful, has taken the time to make sure all of our questions are answered, and had gone to bat to make sure we're getting the best care possible.

  • Mar 14, 2019

    He listened to my explanation of my physical symptoms and asked many questions. He explained the next phase of treatment and answered all my questions.

  • Mar 08, 2019

    Excellent provider. He is creative and easily establishes rapport. I have a problem which thus far has had an illusive diagnosis and he seems up to the challenge.

  • Mar 07, 2019

    A very caring compassionate Doctor.

  • Mar 07, 2019

    Dr. Chahin, I've been seeing Dr. Chahin for two years maybe more, and... he actually rescued me after I had been in treatment with another previous doctor up at OHSU, in the Rheumatology department and... he... took, he saw the symptoms and what was going on and my disease process and he got me on track, and has been incredibly connected to the case and he has even called me in off hours. He's followed me through other things that have happened. So, I would say and he's got a good knowledge because he's worked with a lot of people like me and my disease... process so... I trust what he has to say, so... I probably would have given a ten, it's but you have to know how to*

  • Feb 22, 2019

    He's a very experienced doctor. Very helpful and kind.

  • Feb 10, 2019

    Dr. Chahin is the best. Thorough, kind, knowledgeable about FSHD. I don't know what I would do without him. He found in my MRI that I had no more muscle left in my lower back which another doctor and the doctor providing the MRI failed to notice. This saves me from going back for further injections which won't work in my case. He's continuing to monitor my MD and provide solutions where possible.

  • Feb 10, 2019

    Dr. Chahin was on time, introduced himself, was prepared and had looked over my record, listened attentively, asked insightful questions, explained the plan, and wrote up the order for labs. And he was respectful, kind and is very intelligent.

  • Jan 25, 2019

    Very professional practitioner. Empathetic, informative, smart and actually asked if I had questions (unlike Dr.Karam who was annoyingly opposite).

  • Jan 23, 2019

    The treatment Dr Chahin offers and provides has helped my condition in many ways. The knowledge combined with acknowledging me as an individual has helped me feel confident that I am seen as an individual with a medical condition who has unique strengths and weaknesses ... Dr Chahin is always professional and thorough and able to show compassion and genuine concern for my well being. I notice the attention to detail and how he hears me when I speak ... Dr Chahin is the best in knowledge and options for my condition and is always providing supportive options for how my rare condition affects my life. It has always been reassuring that OHSU has providers that are experienced and very knowledgeable ... Dr Chahin exceeds the standards I had grown accustomed to having ... his knowledge and bedside manner combined have and continue to help me in all the ways I have been affected by my condition .

  • Jan 23, 2019

    He was everything you hope for in your doctor

  • Jan 22, 2019

    Very pleasant and professional.

  • Jan 18, 2019

    Very thorough! The doctor and the interns asked questions, did a very thorough physical exam, and explained to me what he was seeing and thinking. He explained the tests he planned on doing as well. I was impressed that at the end of our visit, he shook my hand, looked me in the eye and told me thetests he ordered would take 4-6 weeks to get all results. The Dr. said “Don’t worry, I will call you when I have all of my results.” I have been chasing my illness for many years, have seen more specialists than anyone should have to see in their lifetime, this is the first time I have walked out of a doctor appt. feeling that THIS DOCTOR really wants to help me, he is hearing me. I look forward to seeing him again!

  • Jan 07, 2019

    My provider very through and explain everything that so I could understand it and I thought it was a great doctor.

  • Dec 20, 2018

    Dr Chahin was friendly, kind and professional. He explained my condition and diagnosis and treatment in a way that was easy to understand. He reviewed my test results. He recommended genetic testing to confirm my diagnosis.He had researched my medical history, and had confirmed my muscle disease dated back to 2001. I appreciate his thoroughness in looking into my condition. I would highly recommend Dr Chahin to others.

  • Dec 20, 2018

    This doctor is one of the most amazing doctors I've ever had. I'm 64 years of age and I've seen a lot of doctors in my time, and he goes above and beyond any measure that needs to be done for patient care. The man is just awesome. I have nothing but great things to say about him. Thank you.

  • Dec 19, 2018

    It was excellent.

  • Dec 16, 2018

    Hi, my wife and I I'm very pleased with Dr. Chahin. She is extremely compassionate and has helped me out a great deal. I'm just grateful to have him as my neurologist and I just feel like he really fight for us in advocate for us and has done all the right things to help help me out. So yeah. I look forward to continue seeing Dr. Chahin and my wife and I are just grateful for everything he has done for us. Thanks very much, Dr. Chahin.

  • Dec 14, 2018

    I met with about 6 other doctors before Dr. Chahin, and he was the one able to diagnose my illness (polymiositis). Dr. Chahin is very caring and knowledgeable.

  • Dec 07, 2018

    Dr. Chahin made a rapid diagnosis of my current condition and a significant change in my treatment. I was pleased to hear his treatment plan. I think this new direction will make a significant change to my condition.

  • Dec 05, 2018

    Dr. Chahin has been... I've been with him for 2 1/2 years. He is the one who recognized the disease that I had and who helped me out greatly. What I have appreciated about him is even on his off time at home or weekends, he has given me a call when things have turned... when I've had a problem he's been there. He's attentive when I'm there in the in the office with him. I'm in a clinic with he and Dr. Gettig, so I have been very happy. Sometimes Dr. Chahin can be excitable, but we both have a great understanding together and I have appreciated his expertise. That's all. Thank you.

  • Dec 05, 2018

    I think that Dr. Chahin is very professional and you know what? He's friendly too when you're scared to death about this crazy disease that you have, so I would rate him... I did rate him a 10, like I said, professional, caring, has lots of questions to ask you, you know, about the last 3 months since he saw you and I like that he does a lot of blood work too just see how I'm coming along and I guess that's it. Friendly, professional, caring, knowledgeable. Those are all the reasons that I give him a 10.

  • Nov 30, 2018

    The best!! I appreciated the thorough exam and explanations. I feel in safe hands now. Everything went smoothly!!
