I enjoy getting to know my patients and understanding their background. By doing this, I can provide collaborative care to achieve their health care goals. I also feel it's important to educate my patients about their chronic disease processes in order to facilitate their overall health and wellness.

Dr Ewing Haas was great and listened to my concerns. I had a longer wait, but I was at the end of the day and understand that this can happen, especially when spending as much time with other patients as she did with me.
I so appreciated her seeing me after being late due to traffic. She was so kind about it and always provides the best care.
Dr. Ewing Haas is great!
I made this appt 5 months ago to establish a PCP. Way too long to wait. But she came highly recommended.
DeEwing is phenomenal!
The NP had obviously spent time reading through my chart before seeing me. She & the MD had a great working relationship. The entire visit was great & very helpful with my issues.
Very friendly and professional. Easy to converse with.
I would have liked more details regarding follow up steps after leaving my appointment. We discussed several different things, and all were not listed on my papers I was given when I left.
I was listened to fully and all issues were addressed to my satisfaction.
I had a wonderful experience with Dr Haas. She spent more time with me then our appointment was scheduled for and yet I never felt rushed. She patiently let me ramble on about a tragedy I've been struggling with. I felt very cared for and cared about.
Fantastic experience!
Dr. Ewing-Haas is so welcoming, professional, and knowledgeable. She truly is an amazing doctor, and her assistant is very special as well.
Dr. Ewing is top notch- she listened to my concerns, provided recommendations that were practical and was incredibly encouraging. I couldnt ask for more in a provider!
Friendly staff. Awesome doctor. I highly recommend. She addressed all my concerns.
Very positive overall
Dr. Ewing Haas is a treasure and I'm fortunate she's my PCP.
I have already recommended Dr Ewing to several coworkers. She is knowledgeable and kind and a great communicator. Lucky to have her! The rest of the clinic staff was also kind, thorough and efficient.
