Oct-2024

For 5 years now I have been struggling with ongoing health issues. I’ve been seeking a Doctor that is intelligent, knowledgeable, and willing to actually hear me. Because I am young — many healthcare professionals brush me off and tell me I just have ‘anxiety’. Dr. Tseytlin was on time, attentive, and answered any questions I had without making me feel lesser or rushed. He even brought up other specialists, recommending that I receive further evaluation as well. Though I don’t have my exact diagnosis yet, I don’t have doubts that he will help me get there. He is an example of how every Doctor should be.

I had a wonderful experience with Dr. Tseytlin and found him to be very caring, compassionate, and incredibly knowledgeable. He thoroughly listens, explains himself, and ensures that I understand our discussions. His depth of knowledge is amazing and bedside manner is perfectly appropriate. I did not have the same experience as some of the negative reviewers on here; it was quite the opposite. I would highly recommend him and would not hesitate to return to him for future concerns. Good doctors like him are hard to find!

Dr. Tseytlin has effectively saved my life, and my ability to live it with relative normality. When we met 2+ years ago, I was almost completely immobile, feeling hopeless, and unsure of what was happening to me. He got me on track almost immediately, prescribed the medicine I now take regularly, and is largely responsible for my success and well-being as I sit here writing this. Can't thank him enough for all of his continued assistance and support.

The disease of RA is painful, depressing, and complicated to understand, Dr.T helps me understand my treatment process by taking his time to explain no matter how many questions I have. He’s professional bedside manner is comforting. He’s always on point with my treatment plan. I know I’m in great hands. Thanks Dr. T for encouraging me to keep pushing forward and helping me to have a better quality of life.

I really like Dr. Tseytlin, and I can be very critical of the care some physicians provide. He listens, he has a nice manner, and he gets to the point. I went in with symptoms that were neurological, but I was getting nowhere fast getting a neuro appt. He knew exactly what it was in seconds, and referred me to the appropriate Dr. I have an appointment in 3 days time to get the ball rolling. The ladies at the front desk are all very personable and professional. Given my experience, I would recommend this rheumatology office.

This is your sign to schedule your appointment now! No need to look elsewhere! Most informative appointment I’ve had in a long time. Such a breath of fresh air. He will help you get to the root cause and not just prescribe a bandaid.

I had been with another practice for almost 20y but my Dr. retired and I was shopping Drs bc I was unhappy with his replacement who did not respect my views/what I felt was best for me. I agree with Sara's review, Dr Tseytlin was a great listener, very informed on Covid treatments and very thorough with my very long medical history. He asked all the right questions and gave good answers. I was impressed, I felt heard and respected and that we collaborated well. I feel like I am in good hands for the long haul. :)

I don't know who the other reviewers saw, but it wasn't the Dr. Tseytlin that I saw. His bedside manner was great and he went through my history thoroughly and had a conversational manner. I felt like I was collborating with him on a diagnosis and course of treatment and felt very listened to and supported. This is a very difficult specialty that takes time to reach a diagnosis but that doesn't mean the care team isn't supportive. I felt like I had a worthwhile and frankly fantastic visit with Dr. Tseytlin. I was more annoyed by the appointment and front office help than any member of the care team.
