About The Provider
Board-certified physician Jennifer Slack, MD, is enthusiastic about helping patients live healthier, more content lives and working with them to manage and improve chronic conditions. Specializing in internal medicine, she brings 20 years of clinical and leadership expertise in the field. “I love developing long-term relationships with my patients,” she shares.
Since her youth, Dr. Slack has always gravitated toward medicine. Even in grade school, her book reports and presentations focused on societal medical issues. Over time, her fascination with health and science grew and she decided to become a doctor. After earning her medical degree at the University of Arizona College of Medicine in Tucson, she completed her residency in internal medicine at Providence Portland Medical Center and attained certification by the American Board of Internal Medicine.
Dr. Slack has treated patients of all ages in a variety of settings, including office-based practices in Portland and clinics for underserved populations in Arizona and Mexico. Today she brings personalized, whole-person care to patients in the Parkrose area. “The mission of Adventist Health resonates with me,” she says.
When not busy at work, Dr. Slack finds fun and relaxation by hanging out with her two crazy dogs, watching British TV shows, reading books and listening to podcasts. She recently started a new hobby: building Lego sets. Occasionally she enjoys cooking.

I absolutely love Dr. Slack! She is so personable and attentive and I feel like I am being heard after being brushed off by other providers. She is a breath of fresh air!

I have already recommended her to many of my friends and they all are very pleased. In some sense, I don't want to recommend her to too many people because then I won't be able to get in to see her Just joking of course :-)

Dr Slack is superb!

I've been a patient of Dr. Slack since the mid 1980's, following her from one location to the next as she pursued her career. I choose my medical coverage based upon who accepts her as a preferred provider. The primary reasons for my continued loyalty are her professional competence and her ability to listen and allow me to have input regarding my own health decisions. There's a mutual respect between us that is rare.

My visit to Adventist was for a "Well Visit", and as such, had a very general focus, but the one semi-acute concern I raised received scant attention.

I could not be more pleased.
- 3 out of 5 starsReviewed on 5/30/2025
Not at all personable, seemed uninterested, one comment I made was completely ignored. Anything I tried to inject was basically not responded to. I felt zero care or empathy. Unfriendly, I don't recall them even smiling. I left feeling like I had done something wrong, it was unsettling.

I saw Dr Slack at her previous practice and she was much more engaged and interested in providing care. I really don't know why my appointment at the new clinic felt so rushed and perfunctory.

Dr. Slack was treated me very well, listened to my concerns and answered them promptly. She offered help in setting up a referral as well as testing options. Made me feel like I was dealing with a person concerned with my health care and quality of life and not a system or a doctor whose primary function during my appointment was data entry and getting "out of there" as quickly as possible.

I followed Dr. Slack to Adventist because she is a remarkable doctor and person. She has a way of listening and sharing that is both professional and respectful of me as a person as well as a patient. She engages with me and helps me be part of the solution. It is too bad that the medical community doesn't have more doctors like Dr. Slack. I could go on but suffice to say that I have great respect and admiration for her.
