Clinical Expertise

Family medicine (including newborns and pediatric patients).

Philosophy of Care

I take the time to learn your outlook on life. My goal is to work with you to develop a plan that integrates your health needs with your readiness to make changes. From there it is about teamwork, celebrating success, and creating new plans that address setbacks.

Personal Information

I enjoy puddle stomping and "worm saving" with my three kids in the rainy Washington weather, enjoying the vast variety of food my husband the chef creates, traveling to see family in Honduras, and gardening or visiting the nearby forest. I speak Spanish and have worked and traveled extensively throughout Latin America.

Community Involvement

International volunteer work in Latin America with HIV+ orphans in Argentina and health outreach with indigenous Guatemalans. I have attended international health improvement conferences. I mentor and precept new Nurse Practitioners and Advanced Nurse Practitioner students because this improves the quantity and depth of the care my patients receive, and makes my days more fun.

I always talk highly of Rebecca, she is amazing. I have had lots of bad experiences with the nursing and front desk but I stay cause Rebecca is so amazing.

Great doctor!

I love seeing Rebecca! She's friendly and caring, but doesn't waste time. She remembered what I'd talked with her about before and had good suggestions for things to change. She writes it all down and prints it out for me so that I can remember, too. I was impressed that she remembered stuff from a year ago! (Even if it's just that she checked my chart before coming in, that's much appreciated.) She is flexible about ideas and listening to what I can or can't do, and she was the first one to solve a long-term problem for me.

Dr. MassKrajewski is an amazing doctor! I'm always amazed how well she knows my file and history and as well as her patience and care in listening to all my concerns. She is always familiar with a lot of the newer schools of thought. A+++ doctor!

I've already recommended to friends and family who see Rebecca. I was introduced to Rebecca from a referral as well!
February 04, 2021
The only reason I wouldn't recommend Rebecca is so that I could get in to see her more :) She's excellent at taking care of her patients and adapts to meet their needs in the moment.

I have had a hard time feeling like the providers we're sympathetic to my issues
