Again, I would highlight what I said above: I was listened to, I was questioned thoroughly about my symptoms, I was given a confident path to follow for recovery, I know when and how to check back in if I am experiencing some off the path symptoms.

I am truly grateful for the exceptional care I have received from Dr. Ruderman. Throughout my journey with sarcoidosis, he has been a steady, compassionate, and knowledgeable guide. His expertise in rheumatology, combined with his genuine concern for my well-being, has made all the difference in my health. If it were not for his professionalism, attention to detail, and dedication to finding the right treatments, I honestly don't know what would have happened to me. He listens, he explains, and he makes sure I always feel supported and understood. Dr. Ruderman is not just an outstanding physician_he is a blessing in my life. I cannot thank him enough for the care he has provided and the confidence he has given me throughout this difficult journey. If you'd like, I can make it shorter, more emotional, more formal, or more direct_just tell me!

Dr. Ruderman has been my Rheumatologist for many years. He is incredibly knowledgeable, great to work with, and he understands that while he specializes in Rheumatology, his patients are more than just his area of focus. I always appreciate his willingness to listen and go over treatment options, and I know that he will give me the information I need to make choices in partnership with him when medication, testing or intervention is needed. He keeps in mind my complicating factors and communicates his thoughts on how my other medical issues will be impacted by whatever he and I are doing Rheumatologically. I feel lucky to have him as my doctor and an integral part of my care team.
