Stefani’s coaching is delivered with passion, enthusiasm, and creativity! I take my development seriously and see it as a means to grow both personally and professionally. Going through her program helped me to get to a new level of awareness. It’s not just a single book, study, or assessment…the whole package provides results that are, and will continue to be, life changing.

Lisa Perfetto, Director, Quality Assurance and Operations Support at Independence Blue Cross

Stefani’s executive coaching has my highest recommendation. Many tools are utilized to provide a high level of self-awareness (that is truly life altering) along with realistic action planning to build upon your strengths. Lots of great resources are skillfully presented with expertise and are supplemented with invaluable one-on-one coaching sessions.

Rachel Kucera, Sr. Consultant, HR Business Intelligence & Metrics at Lincoln Financial Group

I highly recommend Dr. Yorges as an executive coach. Stefani has an excellent reputation and is extremely skilled in leadership development tools and techniques. She uses her extensive experience to give context and pragmatic value to professional development. She is an expert at what she does and has a lot of value to offer.

Tracy O’Connor, Human Resource Manager at Johnson Matthew

Stefani’s outstanding coaching has been extremely valuable in my career. She has helped me excel as a leader while also improving the quality of my life. If you have the opportunity to work with her, I highly recommend you take advantage of it. Using an exclusive cognitive mapping process, Stefani has the ability to both inspire and accelerate her clients to realize their goals.

Heather Ergler, Senior Manager, Vanguard

Working with Stefani has been an absolutely transformative experience! In just six months, she helped me in so many positive, productive ways in both my professional and personal life. Through my work with Stefani, I have built a solid toolkit to help me achieve my goals. A wonderful experience!

Amanda Jefferson, Executive Director, Summer Search Philadelphia

Stefani is an awesome executive coach, I highly recommend her. I recently had the privilege of getting to know her through an individualized leadership development program that my company sponsored. It can often be difficult to analyze oneself and share core thoughts and behavioral motivations with others; Stefani employs a coaching style that is comfortable to engage with, while also being instructive and intellectually challenging. I thoroughly enjoyed working with her over the past 6 months, and found her observations to be insightful and valuable to me on many levels.

Charles Rayfield, Vice President, Corporate Controller at Providence Service Corporation

I found the executive coaching extremely helpful. Eye-opening! Stefani held me accountable for what I committed to work on between our sessions. I really benefited from Stefani’s knowledge and the encouragement she provided. I will reap the rewards for many years to come.

Jennifer Barrett, Director of Leasing and Development, Liberty Property Trust

I cannot say enough wonderful things about the executive coaching that Stefani provided. Stefani is very knowledgeable, but also has a fantastic coaching style that kept me engaged and “on the hook” for the goals I set for myself. Every day I think about something I learned or talked about with her!

Carole McCabe, Scale Leadership Consulting

I wanted to express my gratefulness to you for your investment in me this past year.  I have a greater sense of inner peace, contentment, and resolve since having gone through the experiences of this past year.  Your part in my growth was in no sense little.  God continues to reveal me to me.  While this is painful, I think I realize for the first time how much He truly loves me.  For this I truly thank you.
