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
