The staff at RMPE is top notch! I have two children with growth hormone deficiency and when we moved to Colorado 4 years ago, our pediatrician recommended Dr. Maniatis to take over their care. Our kids have lived in three different states throughout their treatment and while we really loved our other providers, we were thrilled to find this wonderful and caring practice here in Colorado. Every member of this staff from the office, nurses, phlebotomists, and doctor are the absolute best in their field. Both of my kids have now ended their journey with growth hormone deficiency and their treatments were hugely successful in no small part to Dr. Maniatis and his amazing staff. I would HIGHLY recommend this practice to any family who needs a great pediatric endocrinologist!

I have two children with growth hormone deficiency, and RMPE diagnosed and treated them each for 5 years. Each and every visit we were treated with dignity, respect, and friendliness. Everyone who works there is kind and professional, and we were always well/informed of our options and how the treatment was going. I highly recommend this practice!

My son has been treated by Dr. Maniatis and the incredible staff for the past 7 years and we are so grateful for such a positive experience. He recently "graduated" from his treatment and we thank RMPE for providing the support, care, and results that are life changing for him! We left every visit feeling that he couldn't be in better hands and for a parent you can't ask for more!

My son has been going to RMPE for 8 years. We cannot even begin to express how much his experience has positively impacted his life. We are grateful for all of the caring and wonderful providers who played a part in his journey. We felt 100 percent comfortable with the care we got and would 100 percent recommend it to anyone considering using this practice. My son "graduated" with outstanding results and it is bittersweet because we will miss seeing everyone. Do not hesitate to use RMPE for your child and family.

I absolutely recommend this practice! I had 2 boys that saw Dr Maniatis for growth hormone deficiency so we were with him for 16 years total. We saw Dr Maniatis or Mako Sather every 3 months for 16 years so I feel knowledgeable about their practice. They are very professional and run a tight ship. They run on time 100% of the time. Dr Maniatis did a wonderful job explaining all aspects of the defiency and the treatment plan. I felt very comfortable the entire duration of the boys treatment (about 8 years for both boys). My pediatrician at the time kept telling me my boys were fine but I just knew in my gut that something was wrong with how slow their growth was. Dr Maniatis took my concerns seriously and didn’t make me feel like a dumb first time mom. He followed a 3 step diagnosis plan and was very thorough! Turns out I was right, there was something wrong with both of them. But with Dr Maniatis’ help both of my boys got to their full growth potential. We are so very thankful for Dr Maniatis, Mako and their entire practice!! I would give them 6 stars if I could!!! -Nicki Murray
