Andrea at Renew Integrated Health has helped me so much over the last few years and her help continues. Doctors are specified in their education. Andrea knows what they know but looks beyond that. Your body works together and she will go beyond on particular thing and knows how one thing effects another. If I just went by what my cardiologist said to do, I would be in trouble (because I was already starting to be before meeting Andrea She looks at the whole picture not just one thing! So if you're struggling...it's so worth seeing her.

Andrea is one of the most nicest, caring nurse practitioners around! When you walk into her office, you will feel calm and the ambience gives you positive energy. She’s so thorough in her intake of your health history and looks deep into the root of problems. I can attest to her IVs that I received! I was under extreme stress which adversely affected my nervous system negatively and from the first IV that I got, I cannot believe the difference. It really made a huge difference! The concoction she gave me in my IV literally lasted me over 15 days. I had more bounce in my step. The gloom and doom slowly lifted by the nutrients refueling what my body lacked! I felt I had more clarity in my brain and I was able to sleep better & it calmed my nerves! This enabled me to feel better not only physically, but then mentally and emotionally! I continue with my maintenance IVs, and I highly recommend you looking at all she has to offer. There’s many different IVs that she has. I was very nervous and I can assure you also I didn’t even feel the IV go in. She’s that good! I totally recommend Renew Integrative Health!

I love Andrea! I have been seeing Andrea for quite some time, I have been struggling with Hashimoto thyrodisim and some mineral deficiency. Andrea, took time on the very first visit to thoroughly learned about my health history and gain better understanding of my condition. Her approach to treatment is very different from main stream medicine. She cares about your diet, environment you in, daily habits and sensitive to what your able to adjust- in order to improve your overall health. Since seeing Andrea, my health is much better. I learned to better take care of my self and make healthier choices. I have nothing but gratitude and highly recommend Andrea. I had my husband and teenage daughter see Andrea to assess their overall health. I appreciate the call follow ups, check- ins, thorough blood work and overall treatment.

Renew Integrative Health has truly been life-changing for me. Andrea has been nothing short of amazing in helping me manage my fibromyalgia, hypothyroidism, and a very low immune system. Before working with her, I was in a fibromyalgia flare more than half the year. After three years under her care, flares are less than 10% of the time — something traditional doctors could not accomplish in over 17 years. For a few years I also used to be constantly sick — colds, bronchitis, you name it. That cycle is finally broken. Everyone’s journey is different, but if you stick with Andrea and follow her treatment plan, healing is possible. I’m beyond grateful for her knowledge, care, and commitment to getting to the root cause — not just masking symptoms. Highly recommend 💜

I’ve been seeing Andrea for awhile now and she is fantastic. She’s compassionate, and truly cares about getting to the root cause of whatever issue you are coming to see her for. She does a great job of researching symptoms/issues and coming up with solutions based on her expertise, research, and the network of other professionals she works with to solve people’s complex issues. Not only that, but she does a fantastic job managing the human side of these issues and you can tell she genuinely cares about her patients. I was skeptical of the holistic medicine approach when we started, and was forthcoming with Andrea about my concerns. I can happily say she was understanding of them and has proved those concerns I had to be wrong. I can’t recommend her or her practice enough!

We are thankful to have found Andrea and Renew Integrative Health. After a year+ of visits with specialty doctors, multiple medicines and treatments, Andrea was the only provider able to actually pinpoint what was happening with our daughter. She took her time to thoroughly assess our daughter and all of her symptoms, she walked us through each step of treatment with kindness and care and she is feeling better than she has in years!
