Testimonials
What our patients are saying
I went for my routine physical 5 years ago with Dr. Christa Wittmann. She did not like my GI discomfort and immediately sent me for imaging. She found stage one ovarian cancer (very rare to catch it this early) I went onto successfully fighting this most aggressive form of cancer (serious) She took that time to listen to me and how I felt – I did not suspect anything – she did!
—HealthGrades
Dr. Trainor is an excellent practitioner. She is highly skilled and compassionate professional who consistently goes above and beyond. Her deep expertise, combined with her warm and approachable demeanor, makes her a standout in her field. Thank you!!
HealthGrades
For the first time in 30+ years I feel like I have found a doctor who actually listened to my concerns. She went line by line through my medical history and my family history. Dr Eris is kind and straight forward. She was very thorough in every aspect of my exam and ran lots of bloodwork to cover all concerns I had. Her team is just as wonderful as she is. From scheduling to follow up and referrals; Dr Eris’ team made the whole process very smooth.
—HealthGrades
I have been a patient of Dr. Lazarides for 10 years. He is professional, knowledgeable, caring and has a good sense of humor. Dr. Lazarides takes the time to listen to any of my complaints and works with me for the best solution for me, for my budget, and for my health. The staff at the office are fantastic and friendly. I would not hesitate to recommend Dr Lazarides.
—HealthGrades
Dr. Lena Wu Rivas is by far the best Medical provider I have seen in my 61 years. She is always friendly, thoughtful, and puts our concerns first. I can not speak more highly of her. The staff is always helpful and my experience with other medical professionals in this office has always been above my level of standards.
—HealthGrades
As a physician myself, choosing the best physician is critical. It is without reservation that I would recommend Dr. Hass to friends or family. His intellect, patient care and compassion are extraordinary. Highly recommend.—Dr. Mark Taylor, MD
