    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.
