    This was a very good experience. Doctor was totally aware of my cancer background and was able to acknowledge the care I have been receiving at Kaiser. He made me feel I would be able to contact him should I need in the future. He also said things that have given me more hope for my situation.Thanks for his availability and kindness.

    I cannot express enough how grateful I am to Dr. Gubens. Back in 2021 when I received my initial diagnosis I faced the unfortunate obstacle of health insurance constraints which prevented me from seeking his expertise. However my family rallied together and we decided to pay for a second opinion. That decision proved to be life-changing.My previous care team had been unable to identify the crucial bio marker I needed but Dr. Gubens guided us in the right direction. He immediately recognized that they were using an outdated test and recommended the UCSF 500 panel testing. Thanks to his expertise and recommendation we finally found my ALK bio marker allowing me to begin the necessary treatment without delay. It truly felt like he was my lifeline during that time.Now two years later I am finally able to switch my care to Dr. Gubens and I am filled with joy. During my most recent visit my initial impression of him was only reinforced. Dr. Gubens is not only an empathetic and compassionate doctor but also an active and attentive listener. He thoroughly articulated my health history and demonstrated a deep level of care and concern. I was impressed by his thoughtful and engaged approach and I never felt rushed during the appointment.To find someone so esteemed in their field yet so down-to-earth and genuinely caring is a rarity. Dr. Gubens' intelligence and humility shine through and I am beyond grateful for the positive impact he has had on my life. His expertise has made a significant difference in my journey towards better health and I am truly fortunate to have him as my healthcare provider.

    Dr. Gubens is an excellent physician and he was very attentive to our questions and my mom's condition. He did a lot of preparation before hand and patiently explained to us the situation my mom is in and the potential options for her. He answered our questions in detail and seemed very experienced. He respected our opinions and gave room to us to consider the benefits and risks of different options. He was energetic and passionate about helping his patients. We are very fortunate to have him give us actionable advice and we appreciate his great efforts! Look forward to seeing Dr. Gubens again!

    Dr. Gubens reviewed my lung cancer case (diagnosis and treatment plan) as a second opinion and every aspect of his review and our meeting was excellent. Dr. Gubens was extremely well prepared and had carefully reviewed all my charts and test results. Dr. Gubens explained clearly my cancer its diagnosis and treatment plan and confirmed that it was correct. He patiently answered all my questions and concerns and provided his written notes/outline at the end of our meeting. I recommend Dr. Gubens enthusiastically. Thank you.
