Cannot say enough good things about Dr Koala, she is my hero! I had a a really tough delivery with my first baby and was experiencing terrible leg pain during my second pregnancy that went unresolved for months, causing me to leave my job. Dr. Koala took my concerns very seriously, solved the problem in my legs so that I was more comfortable in my third trimester than my second. She listened to all of my fears, helped me make a birth plan that was going to be the best for my body and it’s recovery so I could juggle caring for my toddler and my newborn right away. She showed up in my L&D room and advocated for me every step of the way. She found me an anesthesiologist for an epidural with 20min to spare. Protected my perineum by giving me very specific coaching as I pushed. I cannot thank her enough!
I enjoyed my first appointment (12 weeks) with Dr. Koala at Seattle OBGYN Group. After my 8 week appointment, Dr. Koala initially called me to introduce herself and ask if I had any questions or concerns about my pregnancy. She also offered advice I could take right away between our call and my next appointment with her. During the appointment, she was a good listener, and helped put my husband and me at ease by bringing out the ultrasound machine when we couldn’t find my baby’s heart beat using the Doppler. It was a nice plus to see our little one since we won’t get another chance till 20 weeks!!
Dr. Koala is wonderful. She is very responsive when I have questions or concerns and explains everything thoroughly. She’s also been in time for every appointment, which is rare and amazing.
Dr Koala is always professional, personable and gives me the best care. I’ve been seeing her since she delivered my daughter 21 years ago and now both my daughters are also her patients !
Dr. Koala is amazing! She was my OB for both my pregnancies. I highly recommend her. She goes above and beyond and is very personable.
I have been seeing Dr. Diana Koala for more than 20 years and she is incredibly knowledgeable, attentive, kind and comforting. You cannot find anyone better.
Love love love Dr Koala! Been coming to her for the last 18yrs with my first child in my early 20’s and to my last child in the end of my 30’s. My last pregnancy was the most challenging one health wise and she took amazingly care of me and baby. Her presence of calm demeanor is so soothing when things got a bit overwhelming. Her expertise is very much appreciated. She takes her time explaining and you can truly feel genuine in her character. Truly cares for her patients. Thank you Dr Koala for all you do.
This is my first time going to an OBGYN was pretty nervous but she was really great. Straight forward and let me know things I needed to know to continue my journey on getting pregnant.
I have been going here for a long time, Dr and staff are all very professional. Very thorough and give me time to ask all my questions and makes sure I understand everything covered. I have referred other friends as well.
Dr. Koala has been my gynecologist for a long time and I have been impressed with her friendly yet professional manner. She reviews my medical record and follows up to ensure I am current with the necessary vaccinations and medical procedures.I am very happy she is my gynecologist.
Dr. Koala has delivered two babies for me. The first was a high risk delivery via scheduled c-section; the second was a successful VBAC. Dr. Koala was extremely supportive throughout both pregnancies and deliveries and I was well taken care of. Highly recommend.
Dr Koala is such a kind and wonderful doctor and has assisted me with so much. I highly recommend her to friends and clients as well. She’s the best!
Highly recommend Dr. Koala, I have been a patient of hers for almost a decade and have always appreciated her approach to medicine and patient care.
I'm lucky to have Dr. Koala as my doctor! She is caring, thorough and a great listener to patients concerns. She is amazing! I highly recommend her!
Really great prenatal care and birth experience with Dr. Koala. She’s patient, caring, professional, and experienced. I always felt like we were a team making decisions about my care and that she really respected my wishes. During my labor and delivery she checked on me often and I felt comfortable knowing she was nearby, ready for anything. I felt very taken care of. I’m super pleased with my whole experience with her as my OBGYN. She was recommended to me and I would recommend her as well.
