Hello, I'm Dr. Konstantin Karmazin, a board-certified neurologist specializing in providing high-quality neurological care exclusively through telemedicine. I manage a wide range of conditions with a focus on treating chronic headache / migraines and recurrent seizures / epilepsy. I also provide general neurological consultations, especially for patients who are unsure if they need to wait 6+ months for an in-person visit at their local clinic / academic health center.
I have chosen not to accept insurance in order to provide more personalized and flexible care without the constraints often imposed by insurance companies. This allows me to focus entirely on delivering the highest quality care to my patients, with transparent pricing and no hidden costs. This includes referring my patients to the most convenient and cost-effective resources for lab testing, imaging and other services when needed.
My goal is to provide the same high level of care that you would expect from an in-person visit, but with the added benefits that telemedicine offers. Whether you’re managing a chronic condition or seeking a second opinion, I am here to ensure you receive top-notch neurological care, wherever you are.

My appointment with Dr. Karmazin was excellent. They had the best bedside manner and communication I’ve experienced so far—taking the time to listen and explain everything clearly. I would highly recommend them to anyone seeking a knowledgeable and professional neurologist.
April 20, 2026Michael K.Verified patient
The doctor was great and knowledgable. he was patient and had read through all the history and reports and was patient when I was showing me other reports too. He was very friendly and great to work with....
March 24, 2026Sridhar K.Verified patient
My husband & I highly recommend Dr. Konstantin Karmazin! We live on East coast near many top hospitals but were unable to find a neurologist nearby who could see us in a timely manner. Found Dr. K in WA and were able to get an appointment within days. Via virtual meeting, Dr. provided detailed anaysis of the many test results & info. we uploaded on easy to use portal. It was evident he had reviewed them all prior to our appointment. Dr. also went above & beyond in accessing imaging from another source. Dr. addressed each of my husband's symptoms; possible reasons for them, further testing needed, & specific recommnedations to prevent certain issues progressing & ways to improve each. Answered all questions. After meeting we received a summary of his recommendations. Prior appointment communication with Dr. Karmazin & his Practice Manager, Ms. Hamilton, was excellent & prompt. We couldn't be happier with Dr. K's depth of knowledge, professionalism, kindness, and clear communication!
March 21, 2026Frank O.Verified patient
My experience with this doctor was Absolutely Amazing! He properly dismissed what another doctor had said! It was very important and there is no way that it could have been correct! It was a mistake! I admire him for this! He was on time, very knowledgeable, asked appropriate questions and friendly! What a great doctor!
March 7, 2026Amanda M.Verified patient
Dr. Karmazin took the time to listen to my concerns, explained everything clearly, and made sure I understood the next steps in my treatment. I left the appointment feeling heard and optimistic about moving forward. I truly appreciate the thoughtful and attentive care!
March 4, 2026Carla V.Verified patient
I had a rather urgent issue I needed specialized care for. Neurology consults in my large metro area were booked out for months. I found Dr Karmazin on Zocdoc (his credentials are very impressive) and was able to book an appointment within a week! He took the time to learn about my history and current issues and laid out a very clear plan. I am extremely pleased and grateful that my state allows virtual health care with this most capable neurologist.
February 25, 2026Anne L.Verified patient
I had a Telehealth visit with Dr Karmazin and it was a very positive experience. Throughout the visit he was patient, kind, and had an excellent bedside manner even through a virtual appointment. I never felt rushed and felt truly listened to.
He took the time to clearly explain everything in a way that was easy to understand. I left the visit feeling reassured and well cared for. I would definitely recommend
February 25, 2026karissa L.Verified patient
Dr. Karmazin is an amazing doctor! I felt heard by him throughout the process of diagnosis for my issue, and tests were ordered by my request without hesitation. I left both appointments with him feeling eased in my worry and empowered to take hold of the situation I found myself in with my health. 10/10 recommendation from me!
February 23, 2026Jaiden F.Verified patient
Both the doctor and office staff were amazing . They were both not only professional , and experts but they demonstrated genuine care about our needs, concerns, and provided emotional support during a difficult time. Full package care!

Best doctor's visit I have ever had.
January 26, 2026Anita M.Verified patient
Dr Karazamin is a good listener. He came to the appointment well prepared and reviewed the referral and MRI. He had no experience in VNG or Audiogram. He jumped to conclusions on a couple of key symptoms. He organized his findings. But he did not focus on my core new symptoms. He also downplayed my Menieres Disease diagnosis by a nationally recognized research and treatment medical organization. He recommended three new tests. Provided a skeletal, high level set of next steps. A few off point treatments that have already proven non effective. No short term treatments. No short term treatment for pain, quality of life and safety neurological disorders. Overall disappointed with this Neurologist and will probably seek another opinion/case review by a Dr experienced with Menieres Disease.
November 27, 2025Steve B.Verified patient
Great neurologist! Needed a consultation to discuss dystonia and prior head injuries with new symptoms. Super professional, friendly and a good listener.
Provided me with options for treatment, referrals and future follow up. Easy booking, timely. Highly recommend 10/10
November 22, 2025Ilia G.Verified patient
Worst 33 minutes seen by a Doctor in my life. Please save yourself the headache. He was not sympathetic whatsoever and completely disregarded my need for help by assuming I was a liar about my symptoms... He needs to change jobs.... It was that bad you guys.
October 27, 2025Linda C.Verified patient
Dr. listened carefully and took my concerns into account as the treatment plan was assessed. My questions and concerns were taken seriously and factored into next steps. It was also nice to have more time with a doctor to explain the situation and be able to ask questions without feeling rushed.

He was very friendly and reassuring. Listened and asked questions. Appointment was easy to get when no Neurologist with an office in my area would return a call. Definitely a nice option to have, would see him again.

He seemed to know his field enough to explain it through metaphor. That helps a lot understanding what the doctor is trying to say.

He actually listened to my concerns and had a plan to increase my comfort in place by the end of the visit. It was refreshing to feel heard and justified by a doctor in a world where the patients are often dismissed. Highly recommend him even with it being my cost. You get what you pay for.

Highly recommend this doctor. He asked a lot of questions and also made time to listen to everything I said, and brought up some theories I hadn't considered yet. It's the first time since my symptoms have started where I felt like there was a solid plan to narrow things down. I've spoken to several doctors and none of them were as thorough as he was as far as getting all of the necessary details.
March 22, 2025Andrea S.Verified patient
I reached out to Dr. Karmazin after getting two very different recommendations from two specialists, and he was extremely helpful in talking through both approaches and helping me find the right balance between the two. He thoroughly answered all of my questions and was warm, intelligent, and understanding. I highly recommend him to anyone looking for a specialist or an additional expert to help you wade through complex information, conflicting approaches, additional questions, etc.

Dr. Konstantin addressed all the questions I’ve had for years about migraines and tension headaches. If you’re experiencing similar issues and are looking for a doctor who genuinely cares and takes the time to answer all your neurology-related concerns, I highly recommend Dr. Konstantin.
January 10, 2025Callista C.Verified patient
Really awesome first consultation, he came with clear theories that we can test and an action plan which is not what my experience has been with far too many other specialists that I’ve spoken to about my symptoms
December 19, 2024Alexander B.Verified patient
Dr. Karmazin is young and engaging, putting one more at ease than most other doctors. Confronted with a very unique case and long medical history spanning 45 years, he listened patiently, asked pertinent questions, and then took the adequate decision by prescribing the right examination as well as finding a radiology center very close to where I live where one can quickly get an appointment, staying close to an hour with me, which is longer than most doctors will accord. Highly recommended.
December 17, 2024Rodney B.Verified patient
I had an exceptional experience with Dr. Karmazin. He truly is patient-centered; he’s kind, personable and professional. He took the time to listen carefully to my symptoms and I was heard and understood.
His expertise was evident as he clearly explaining neurological conditions and we created a treatment plan in which I feel confident. I appreciated his patience in answering all of my questions and addressing anxieties I had about my situation.
The thoroughness of the examination was top-notch. I feel confident and optimistic about my health under his care. If you're looking for a compassionate, knowledgeable, and skilled neurologist, I can't recommend him enough. After about a year I found a provider whom I believe can help me.
