Isabel is awesome! From the beginning, my experience has been nothing but positive. Isabel is accommodating and communicates well. She listens and was willing to work with me to achieve my goals and build a plan that I can maintain.

Isabel is patient and friendly. It’s only been a week but she checked in with me after my first shot. She remembered all the important parts of my medical and offered great workout advice for the next week. She has answered all of my questions.

I had an outstanding experience working with Isabel LeMasters at the Optimization Clinic in Medford, Oregon, throughout my GLP-1 journey. Her passion for helping others achieve optimal health truly shines in everything she does. She is incredibly kind, supportive, and consistently made herself available whenever I had questions or needed guidance. Thanks to her expertise and encouragement, I felt confident every step of the way and achieved great results. At 70 years old and 80 pounds lighter, I have never been so healthy. I highly recommend her to anyone looking for knowledgeable, compassionate support on their health journey.

I've been working with Isabel for roughly six months as of this review. She is professional, courteous, and listens to her patients. Everything she does is based on science and labs. There's no guesswork. You meet with her face-to-face. She takes pride in using pharmacies that source high-quality products. I have recommended her to friends and family alike. With her help, I've made gains in the gym and lost inches off my waist.

Great experience here at Optimization Clinic. Finally finding something that really works and helps with not having much appetite. I've lost 28lbs in a short time. I would recommend Optimization Clinic to anyone to give it a try. Isabel does well communicating and answering all questions. Isabel reaches out checking to see how youre doing and feeling after every visit. Its not just a stop by and get the shot and leave its setting down and having a conversation and asking questions that gives it a great experience.

I highly recommend Optimization. Meeting with Isabel was informative and very helpful. I will continue to go each week to support my health goals. As a nurse practitioner, Isabel was able to understand what I need and able to give me guidance.
