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. […]

It took over an hour and a half to see her but when I finally got called in she was very understanding about my needs and medical understanding.

Dr. Thum is always quite personable, thorough and comfortable to talk to.

This was a last minute replacement when my provider called in sick and I was disappointed in my care.

Dr. Thum has always been very caring and personable. I appreciate that she takes the time to listen to my questions and concerns and she does a good job of putting my mind at ease.

Dr. Thum did some lab work on me, but did not provide advice or guidance when lab work showed no positive results

Dr. Thum was very respectful of my needs, knowledgeable about my health conditions and risk factors, and overall excellent. [...]
