    the clinician was rude. did not know the purpose of the visit. abrupt. he was in a rush. no evaluation. This was a complete waste of money. I'm in the midst of complaining to every medical board I can find. I want a refunfd!

    I saw that he did not have good reviews, but I needed an appointment as soon as possible. I should have listened to the reviews. I agree that he was dismissive and had a poor bedside manner. I would not recommend him or see him again. On the bright side, he was on time and I had virtually no wait.

    I find that this provider is dismissive as well as gives advice that oversteps his position.

    this was my first time talking to a therapist. I’m not gonna lie. It’s hard. I’m a man and I should be able to deal with my own issues and emotions by myself, but I realized that I just needed a little extra support. I was very pleased at the end of our therapy session I felt a little overwhelmed, but at the same time, realizing things that I didn’t understand or was able to cope with, he was amazing and I really really appreciate his honesty his ability to understand what I’m going through and he was cool about certain things that I said definitely felt comfortable. The whole time was very very pleased.

    He was able to help me get my prescription refill. But I felt as though he was extremely skeptical of me. And was very short with me, and lacked empathy for my situation. He was very quick to shut down what I was saying. But all in all, it didn’t stop him from providing me treatment. I just hope he improves his provider-patient manner.

    Jean-Jeffrey Marcellus Was nothing short of exceptional! He was compassionate, caring, worked diligently to help me find a treatment option, gave me his contact info and contact info and stayed in touch with even after the visit was over and I was receiving care in the hospital. I am so grateful that California contracted with Sesame and because of that I received such exceptional care during the most medically stressful experience my family has ever gone through. I have never experienced this level of care from a telemedicine provider and maybe not even from any provider. After this experience I am considering using Sesame as my telemedicine provider and joining the plan. I already use a concierge primary care but this was service FAR beyond that! 5 stars all the way but I would rate 25 of of 5 stars it was just abi e and beyond exceptional! I cannot stop raving!
