I love the doctors and staff at Advanced Specialty Care. They are all friendly and professional. Dr. Mello has worked to get my hormones at their peak.

Bob B.

Provider: Gary Gregerson

I am so glad that I found Advanced Specialty Care for Women! The staff there is wonderful! Bethany Mello and the staff helped me improve my health & I feel like a new woman! They are wonderful at what they do, they listened to me and helped me understand what I need to do for my optimal health.
I went to see them about birth control & found out I had a problem with my thyroid & insulin resistance.
I am so appreciative that they caught this and brought it to my attention.
I particularly liked the fact that Bethany referred me to their health & wellness coach, Jennie Coleman in their office; when I wanted to try to avoid a certain medication.
Jennie helped me make better lifestyle choices & attain my weight loss goals.
I truly feel so much better!!! Thank you to all of you at Advanced Specialty Care for Women!

Rochelle P.

Provider: Bethany Mello

I'm so thankful for Dr. G who did my total hysterectomy. He cares about the well being of his patience beyond what he treats. Thank you also to Bethany Mello for taking the time to see past the normal to help me, and of course Jenni for the support I've gotten from her in the last 4 months on my weight loss... I recommend them all to anyone!

Rhonda C.

Provider: Gary Gregerson

I couldn't be happier with my experience with Dr. Gregerson. He's very warm, genuine, and truly wants what's best for you. I am 2 months post-surgery and I am beyond pleased with my results.

Jannae M.

Provider: Gary Gregerson

I would absolutely recommend Josiah Smith in the future to any and everyone that asks me about hormone optimization therapy. He is the best in the business. He practices in holistic therapies and you can't do better than that. He wants to holistically show that you can be well, and I'm living proof that you can do that.

Joe C.

Provider: Josiah Smith

I sleep better, look younger, feel younger, and essentially am 9 years younger based on my inside tracker all thanks to Josiah.

Melissa H.

Provider: Josiah Smith

I have not taken my migraine medicine in 2 months. I have no shoulder pain, zero, and I have complete range of motion in my shoulder and it's just been a miracle thanks to Josiah and the regenerative therapies.

Alisa S.

Provider: Josiah Smith

I don't need my inhaler anymore, and I was told that I would be on them for life, and it's a huge, huge improvement in my overall health. Yeah, and that was something that's very important to me. I have Josiah to thank for this.

Jennifer W.

Provider: Josiah Smith

A week ago, I thought I was gonna be compromised my whole life, that I would have half-kidney function, and now I actually think I have it just about back to normal. I've been through a lot with my health and it's just a testament that if we look outside the conventional box, there are other alternatives available that can truly work with the body's capacity to heal. Thank you Josiah.

Roger D.

Provider: Josiah Smith

TruDOSE has truly transformed my life! After two years of waking up daily with severe hives following gallbladder surgery-despite diet changes and allergy testing-I finally found relief. Within days of my first TruDOSE session with Josiah Smith at Advanced Specialty Care, my hives reduced by 75%, and after my second session, they disappeared completely. I'm now hive-free and living life fully again. Thank you, TruDOSE, Josiah, and Advanced Specialty Care, for giving me my life back!

Jennie C.

Provider: Josiah Smith

TruDOSE with Josiah Smith has been life-changing! After 10 years of struggling with psoriasis and rheumatoid arthritis, my confidence and energy were at an all-time low. I was hesitant about pharmaceutical treatments due to side effects and costs, but TruDOSE gave me hope. Within three days of my first session, my scalp was completely clear, patches on my arms and shoulders disappeared, and my energy soared. The pain and inflammation from my arthritis significantly decreased, and I now feel confident wearing anything I want and waking up energized. I can’t wait for my next session—thank you, TruDOSE!
