Dr. Shultheiss talks very, very softly, and at times it was difficult for me to understand what he was saying. But I still think that he is an excellent doctor.

He is very kind and caring. He always listens. He gives his best medical advice but does not steer you in one way or another.

Dr. Schultheiss is professional, friendly and caring. He treats patients with dignity and consideration.

04/23/2024

Dr. Schultheiss explained to me that I had had a bone scan last year that I did not recall. After checking MyChart, I saw the procedure listed, read the results and realized that I had never seen results. I am grateful that Dr. Schultheiss brought that to my attention, and I will now pay more attention to MyChart.

04/18/2024

Always a friendly greeting and asks how I am doing.

01/03/2024

After this appointment I have a lot of faith in Dr Schultheiss.

12/29/2023

Dr Schultheiss is the reason that I continue treatment at this facility. Some of the other medical staff are less than diligent, and are not as knowledgeable or caring as they should be.

12/20/2023

My provider in the group, left and Dr. Schulthiess was new to me. He knew my history, so he was prepared for my visit.

12/13/2023

Very good at explaining things to me

12/07/2023

I am sorry that I moved my care closer to where I am living.

11/21/2023

One problem was the initial contact people weren't aware of the procdure for Infusions. They did not send me to the correct room (for installaton of a catheter and the blood test). This caused a delay in the start of the infusion prodedure.

He gave us knowledge and hope.

I'm sure it will be a fruitful relationship.

Doctor Schultheiss set clear expectations for us regarding treatment and side effects. He listened carefully to my questions and gave clear answers. His treatment effectively treated my cancer.y

08/31/2023

The people are very good; I find it odd that I'd been filling out the 9 pg questionnaire, only to have the Nurse interview me and ask me a bunch of questions that are already answered on paper. No one asked me for the questionnaire, so I asked the Dr. He said give it to the Nurse or Admin in the front desk. A-OK.

08/30/2023

Dr. Schultheiss is a blessing!!!

08/26/2023

Was not happy with the nurse in the lab, maybe she is new?

07/06/2023

I waited 43 minutes for the Dr. to call me. This is unacceptable. My time is valuable.

They were all GREAT! Extremely friendly, down to earth and made my (easy cancer) journey very safe!

11/23/2022

When discussing different drug options it would have helped to have it written down. They all seemed to run together.

11/07/2022

Dr Schultheist offered to consult with a professional in a related area of care to get the additional information I needed. Thanks to his caring concern, I'm sleeping better.

10/22/2022

Very sad. I just wanted a treatment plan for my [condition]. I paid out of pocket knowing my insurance wasn’t going to cover it. I wanted to come there for treatment. I am forced to go somewhere else away from home, friends and family and more money. I’m sad no one seems to care. I know I have [condition] but shouldn’t mean I don’t deserve treatment

10/15/2022

Brilliant doctor who has taken a special interest in my complex medical conditions

10/05/2022

Totally a positive experience and very happy to have Dr. Shultheis as my doctor

08/14/2022

Frustrated over new computer system. Hopefully, that will get better with time

07/18/2022

______ by looking at computer. Not too concerned about my feelings towards my health. I left upset about visit.

07/17/2022

Love you folks.

07/15/2022

I am very hard of hearing so can be difficult to actually understand what provider is saying as his voice is very soft. It also is very caring and kind.

06/29/2022

This visit was for follow up & comparison of PET scans done 1 year apart. At present I don't see *Dr. Schultheiss on a regular basis.

06/24/2022

This doctor is top notch - best I've had - ever!

06/15/2022

Was great.

05/25/2022

He is always so concerned and understands

05/12/2022

I always look forward to my office visits with *Dr. Schultheiss.

05/12/2022

A new computer system was being put into practice - it was distracting to both myself and staff. Provider and staff were professional but seemed bothered they had to focus more on the computer than the patient they were treating.

05/10/2022

He got confirmed what my PC had said about waiting to stop taking aspirin until after I finished with my oncology meds next year. He got back to my PC within 10 minutes of my working with her to approve an estrogen medicine she asked if I could safely take (my CA is estrogen fed). I appreciate the teamwork he and my PC practice.

05/05/2022

Overall, Dr Schultheiss listens to and answers my questions. I will start on an aromatase inhibitor and I know there can be side effects, which Dr Schultheiss mentioned, but I did not write-them down, so I am not sure of them. I won't see him for a few months, but I am glad to know I can use MyChart to ask follow-up questions.

04/27/2022

Great.

04/25/2022

Very pleased

04/20/2022

It was a thoughtful, insightful visit.

04/15/2022

04/11/2022

All my illnesses hit me at 90 yrs. old. I was on the job 30 years only off 5 days sick not much experience with drs. = I was very pleased.

04/11/2022

*Dr. Schultheiss is highly professional, personable, and extremely competent. He instills great confidence and I am very pleased and grateful that he is my oncologist.

03/22/2022

The doctor and staff were polite, courteous and did their best to put me at ease. I have ongoing anemia and it may be a precursor to worse things. Only time will tell.

Great!

01/20/2022

Very pleasant - Not condescending. Understood that I had a lot of knowledge about and had researched my condition. Set up future appointments/treatments 'just in case.'

01/20/2022

Excellent visit.

01/20/2022

My esophageal cancer, came back in Oct. 21, I told *Jennifer F_____ about my problem swallowing, thought that was a red flag, however for the past two months, I haven't got any treatment. Today 1/12/22 I'm seeing *Dr. Sales for rad. treatment, I can't swallow anything *Dr. Schultheiss want to do immunotherapy but I don't know when that will happen? I'm hoping for the best!

01/20/2022

My provider is always prompt and thorough.

11/09/2021

*Dr. Schultheiss is very caring and knows what he is doing. He is one of my favorite doctors!!

11/04/2021

The dr. took time to explain what was going on.

11/02/2021

*Dr. Schultheiss is the best!! He listen and calls Seattle Wash. dr. if anything changes.

10/23/2021

The Doctor listens well to me, and answers all my questions. I enjoy his professional yet friendly manner.

10/22/2021

Karl is the best!

10/06/2021

*Karl saved my life once, hope it can do it again!

09/23/2021

The office was busy, so the wait was understandable.

09/23/2021

Doctor and all assisting staff very professional at all times. My appointments all set by time - 1st blood draw - wait for results 2nd - Hour later - See doctor for about 1/2 hr. - 3rd go to another room for my infusion and/or injection - When waiting were offered drinks and snacks.

09/22/2021

It's always good!

09/14/2021

He is very direct and to the point. He takes care of 'business' and I appreciate that very much.

09/13/2021

I had to call several times to try to make an appointment. It took a week for someone to call me back.

08/25/2021

I have hemochromatosis. I come in every 6 weeks to have iron count the questions I answered about provider are from past visits, but also are about the staff who takes care of me when I have phlebotomy.

07/30/2021

Dr. Schultheiss has his style, one which I find most gratifying. He is the imminent professional, yet shows the humanity that builds confidence in one who is scared half to death! Despite a better than average knowledge, I have never been 'talked down to' nor dismissed. His advice has been spot on and absolutely directed at the issue involved. He does this through listening, being totally up to date on a patient's status and with a carefully crafted sense of humor!

07/20/2021

I was very happy and impressed to hear back from the doctor himself to explain the results of my blood work and plans for the immediate future. Thank you!

07/16/2021

As expected.

07/07/2021

Physician had not received a drug/therapy option and it's applicability in my situation. This option has been discussed 3 months earlier with a phone reminder from me 10 days before this appt. with commitment from doctor, he would review it.

06/23/2021

Oncology phlebotomist is ALWAYS fantastic. Oncology reception/front desk went out of their way to accommodate last-minute change due to foster child.

06/22/2021

Excellent as always.
