Dr. Thom is fantastic and cares so much. I feel so lucky to have been referred to him. He is exceptional and I have many medical issues and he is helping me to cope and eliminate worries of dealing with so many problems with medical care. He even called me on a Saturday evening to ask if I was okay. I can't say enough good things about him. I appreciate him so much!
My app. was for yearly physical but the whole visit was about 15 min. He only listen to my heart and lung!! Nothing else!! Is this normal??
Dr. Thom is a professional that closely listened to my needs. He took more time than I thought he would with me.
I have only seen Dr. Thom once so far; I like his calm and quiet disposition and the fact that he didn't rush the appointment.
Dr. Thom is great - so glad to have him as my new doctor.
"Best ever."
Dr. Thom showed a level of care and understanding that I have received from few. Thank you Stanford & Dr. Thom for the caring, understand & compassion.
My first visit with Dr Thom. Became very comfortable with him. Excellent, including follow-up. Recommendation of a person is not made based on just one interaction/visit.
Really appreciate Dr Thoms excellent bed side manner. He didnt rush my questions and I felt my questions were addressed thoroughly.
Dr. Thom is very detailed and takes his time listening. He was as concerned as I was that we treat the pneumonia correctly and in a timely manner. I was confident that he was taking me in the right direction. He was good at answering all our questions and explaining things in detail. In my and my husbands opinion he is an asset to the clinic.
I hope my husband changes to Dr. Thom - he's excellent.
I was delighted and very happy about my visit with Dr. Thom, whom I met for the first time at this appointment.
