Dr Thum and her staff are always attentive to my needs, spend appropriate amount of time with me, I never feel rushed. I feel they are there for my best interests and to resolve and health issues or questions I have.

I love Dr. Thumb. She makes me feel so comfortable and really gets to know me. She makes sure all my questions are answered and lets me k ow what next steps are whether it's checking up in a year or doing a follow up exam. I won't go to any other gyno. She's the best.

She was a new doctor for me, but made me feel comfortable right away.

Dr. told me to get blood work done but I dont know where or what to ask for or how to even go about doing that. I had asked for the test to be done there and then and it didnt happen. Dr was very late to my appointment (1hr) and then rushed through. I didnt feel very important.

excellent care, explains everything clearly and thoroughly, well informed re my health

I saw Dr. Thum because the last health care provider, Dr. [...], was extremely difficult to see do to her extremely busy and limited work schedule. After years of struggling to get appointments in a timely manner, I decided to find a new doctor. Dr. Thum took the time to review my mammogram results and gave me handouts that I could take home and read to further understand my mammogram results. I appreciate the fact that I was able to get an appointment in a short amount of time and I look forward to seeing her in the future.

I always come away from my appointment with the feeling that Dr Thum genuinely cares about women's health issues, as well as my overall well being.

My time with Dr. Thum was very rushed and curt. Felt like I was being rushed out and my appointment was nearly 2 hours late.

She was very helpful in explaining my condition.

getting the appointment was difficult. I had to call 4-5 times and finally a supervisor put me on a list to be called. I understand this has been fixed but it was very took me 3 months to actually schedule the appointment!

Dr. Thum is a very caring and nice person.

my care provider did not listen any of my symptoms or discomfort or problems that I faced during pregnancy or after surgery.i haven't felt any time that I have been seen by any medical doctor throughout my pregnancy and postpartum period.she neither have any time to address any of my issue nor pay attention to any of my problems or discomfort .I wanted to be seen by a doctor in most of my pregnancy period appointments.but only a few appointments have been made by my care provider the others were made by the nurse practitironers.

Dr. Thum is wonderful and always seems to have plenty of time to discuss my issues. She's respectful and aware of my previous history.

My care provided is very approachable, easy to talk to.

I just felt a little rushed, so I didn't get a chance to ask the questions I would have liked.

Dr Thum never seems to be in a hurry & always makes eye contact.

Since this was my first visit with this provider, it felt rush, like she didn't have much time to spend with me.

I waited over an hour (in the waiting room and the patient room combined) just for the doctor to come in and tell me there really isn't anything she can prescribe me to help my situation except for one medication that I specifically told her I did not want to take. She kept trying to push me into taking that medication but in the end she ordered some blood tests to see if I was able to take any other medication. She seemed very uninterested in helping me find any other way of dealing with my health problem except for short term things that I have already and am already doing.

Dr. Thum was very empathetic and a patient listener during our visits

Typically good and pleasant experiences- most appointments the provider was slightly late and the interactions seemed somewhat rushed.

I needed to have a referral for an ultrasound but I had to call twice asking for the order to be sent. It took over a week for the specialist office to receive the order, which didn't leave much time for scheduling considering how quickly they wanted me to come back to have it done. [...]

I'm disappointed at the time frames given for appointments, it is not patient friendly.

Took along time to get to see Dr Thum but she is very good so I can see why

I have been with Lisa Thum for 15+ years. Always the best experience,

Each time I go in I end up waiting for at least 20 mins, onetime 45. Then my appointment is only 5 mins long. I finally have access to Mychart (after 6 months) and it upsets me that what is written in my charts is not what happened in my appointment. I always leave my appointments feeling as though I am leaving without any information. […] This is my first time pregnant and information is what I need. I feel as though stuff should be gone over in a routine matter rather then "Do you have any questions". […] This is what has led me to leave my provider at 6 1/2 months pregnant and go to a midwife. […] Another thing is when trying to access my charts/ pay bills it seem that my information is never entered in the system so I have to call in and give my information all over again. […] It is very frustrating and seems very unprofessional. […]
