MD Gerboth displayed my test results; walked me through the Cat Scan views explaining in detail what it was showing. He was a great listened, was interested in my questions and gave me excellent easy to understand answers. He laid out a plan for me to follow with more tests and said he would be in contact with me with more information. Heidi his RN was also excellent and a comfort. Both could not have been better. MD very knowledgeable! I felt they both were interested in me and want the best for my well being!!! I look forward to what they can do to maintain my health!

Dr Gerboth has taken time to explain test results, understand how to better manage my health, helped schedule specialized physical therapy to maintain/improves my health, and order specialized medical equipment to maintain my health. He and his staff have been extremely helpful in encouraging me to better manage my health. He is honestly about the problem, sets reason able goals and expectations, personalizes his advice to my specific needs, and provider holistic care. I feel privileged to be his patient!!

Patient verified via Press Ganey

I have no complaints or issues I am uncomfortable with except the for the numerous emails & text reminders for the appointment. I know all people are not dependable about showing up when they have appointments, but I am, and the constant reminders almost feels like badgering. This provider is respectful, prompt, professional, and makes me feel comfortable and cared for.

Overall Rating: 5.0 2026-01-25

Patient verified via Press Ganey

Everyone was helpful and supportive, the front desk, the doctor's assistant, and the doctor. The x-ray was a follow up and Dr. Gerboth wanted to discuss the results in person. An exam corroborated what the x-ray showed. All good news. BTW The appointment flowed smoothly and quickly. From beginning at the front desk until I left the front door was, maybe, 15 minutes.

Overall Rating: 4.0 2025-02-08

Patient verified via Press Ganey

Not sure if the provider understood my whole health history when advising me about this diagnosis. Provider was respectful and professional; not sure his treatment recommendations were well thought out. It seemed that he knew his specialty well, Im just unsure about the future and when to be retested, what symptoms are risky, and what to do in the future.

Overall Rating: 5.0 2023-09-24

Patient verified via Press Ganey

Nurse was very attentive and easy to relate to. Her personality was friendly and caring, and she responded well to our humor. Doctor was clinically efficient and decided the main problem would be addressed by our gastroenterologist rather than him. Was not concerned about the slightly hazy lung CT results and saw no need to treat it.

Overall Rating: 5.0 2023-08-06

Patient verified via Press Ganey

Dr. Gerboth was probably the most attentive medical provider I've had in years. He came into my appointment with knowledge of my medical history and asked questions in a respectful and supportive manner. I felt heard and listened to which for an overweight older female is not a common occurrence. We are somewhat invisible at times.

I was very satisfied with my appointment with Dr. Gerboth. I appreciated his experience, knowledge, thoroughness and Insight into my pulmonary condition. He was respectful and personable in his manner. This was my first appointment with Dr. Gerboth, but I plan to continue to rely on him as I deal with ongoing lung problems.

Patient verified via Press Ganey

Dr. Gerboth was excellent in providing me care. He was well prepared and knew every detail of my medical history! Took his time in reviewing my pulmonary function test and previous chest x-ray! Extremely reassuring about my respiratory issue. I have never left a physician's feeling so relieved and grateful!!

Patient verified via Press Ganey

This is my first time with this clinic. It was professional and I was grateful to get in on a timely manner. It was a consult for lung disease and I will be following up with a test the Dr. Is supposed to set up. I am waiting for that referral for a pulmonary lung function test.
