"Wonderful and amazing people and so very helpful and knowledgeable."



"Katherine is amazing. She has helped me identify so many hormonal and health issues going on in my body that no other doctor was able to fully identify. She goes above and beyond in the testing to get to the root of the problem instead of just masking symptoms with meds. She has me on a protocol that literally gave me my life back. I am 40 with 3 kids. I live a very healthy lifestyle. I eat right and exercise/lift weights and do all the wellness things. But that still wasn’t enough for me to feel good with my underlying health issues. She doesn’t just want you to feel ok and what status quo says you should. She wants optimal health and you feeling great and energized and that’s the gift she gave me. I see her routinely to tweak things as needed. She is caring. She understands. She actually listens and validates and makes you realize that you should feel good and if you aren’t there is an underlying reason. I can’t thank her enough for how much she has helped me. I am a better mom and wife because of her. But most importantly a better version of me because I feel good again. She is truly a gift."



"I cannot say enough about Katherine and her entire staff. As a health coach, she has been terrific and this entire process a game changer for my wellness, habits, etc. She and her entire team are the most professional, caring, genuine, and supportive group you could only hope to have on your health and wellness journey."



"Katherine is the BEST. She is extremely knowledgeable and extremely THOROUGH. Katherine truly cares about her patients and wants them to thrive. All practitioners should conduct themselves the way she does. She is a hidden gem."



"I appreciate the fact that with Katherine I can get input on traditional forms of medicine but also, more effectively, holistic treatments. Great staff as well!"
