Patient Comments

  • Dec 31, 2019

    Great doctor and staff but the wait was long

  • Dec 22, 2019

    I was seen within 30 minutes of my appointment. Dr. Chahin didn't make assumptions. His approach is to look at my condition with a fresh look, discounting prior assessments, and considering new diagnostic tools (genetic testing).

  • Dec 21, 2019

    Dr Chahin has been an excellent DR for me. He understands my disease; and has been very caring and encouraging. He appreciates how I have progressed and keeps me going. He has a very positive attitude.

    Dr. Chahin is amazing. He cares for his patients. He's very knowledgeable, a great person. I'd recommend him to anybody. One of the best doctors I've ever had.

  • Dec 17, 2019

    I came to Dr. Chahin with a difficult condition to diagnose. The two doctors I saw previously referred me to Dr. Chahin because I needed a specialist. After a couple hours of testing, he made a diagnosis and prescribed a course of treatment to eradicate my autoimmune condition. This was a follow up appointment to evaluate the progress of that treatment. Dr. Chahin performed several strength resistance tests of which I previously had mostly failed. However, today, I passed most of the tests that showed my body is responding positively to the course of treatment. His excitement over the positive changes was both contagious and encouraging. He altered my treatment slightly as if to fine tune it based on my success. It appears that Dr. Chahin used a healthy of dose encouragement and reality in discussing my progress. I left feeling very optimistic, yet knowing that I am not “out of the woods” and it was made clear to me what I need to do...without uncertainty.I consider myself lucky/blessed to have Dr. Chahin as my doctor. He empathy, concern, and kindness totally create a healing environment emotionally.

    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
