Dr. Dolores Zumbado

I understand the struggles many of you face when trying to lose weight. I am not a naturally thin person. I studied nutrition for that very reason – to figure out once and for all how I should eat to maintain a healthy weight. I was doing everything right – eating nutritious balanced meals and exercising religiously – but I still struggled with my weight. I consulted physicians (you must be eating too much or not exercising enough, bah), nutritionists (you have food sensitivities, by the way the test is $500), and even friends and colleagues (maybe you’re not eating enough?). My internal preoccupation with weight, and my disgust with my increasing body mass was nearing a tipping point. That’s when it hit me – maybe how we think about dieting is wrong. If calorie restriction and exercise are valid methods of losing weight, why can so few of us do it? Seriously, we Americans can’t all be undisciplined and lazy. So I began to think less about the weight loss paradigm and more about how the body works. With my knowledge of nutrition and my understanding of physiology through my chiropractic training and practice, I realized the importance of integrating the two. There in started my odyssey toward becoming an Ideal Protein coach. The Ideal Protein Weight protocol is backed by sound science, and just makes sense. I have spent the past decade educating the lay public on basic tenets of physiology and how the body maintains a healthy weight.I realized that access to a structured and proven diet plan grounded in science was still not enough. We needed to provide education, mental training, support, and community to eradicate the culture of obesity in this country. I believe you deserve to live a full and healthy life in a body you love. My team of passionate coaches and I want to make that happen for you. Together we can do this! Dr. Dolores Zumbado


Kathe Montgomery

In addition to compassionately coaching many of our clients, I am the administrative whiz who keeps the office running! I majored in dietetics while at the University of Maryland and always had an interest in cooking and nutrition. I lost 35lbs in 4 months on the protocol before joining up as a coach with Dr. Z in 2010. I have raised three children and stayed home for several years to homeschool them. Outside of Dr. Z’s, I enjoy spending time with my family and friends, sewing, reading, walking, and cooking.


Karen Deblasio

I graduated from Palmer Chiropractic College West in 1998. With my medical background, I am a crucial member of the team, reviewing each of our client’s health profiles before they begin the weight loss protocol. I was first introduced to Ideal Protein when I noticed many of my clients dropping significant amounts of weight on the Ideal Protein protocol administered by Dr. Zumbado’s clinic, which was at the time sharing space with the wellness center where I practiced. In 2010, I lost 50 lbs in 4 months on the protocol and shortly after began exclusively coaching Ideal Protein with Dr. Zumbado. I celebrate my job daily and feel truly blessed to bring the same results that transformed my life to others.


Renee Brodsky

I have 8+ years of coaching experience, and have a wellspring of knowledge regarding products and the issues and challenges that our clients face. I lost 25 pounds on the protocol in 2008, inspiring 12 family members, who lost between 10 and 85 pounds, to join the Ideal Protein community. When not coaching, I enjoy spending time with family, traveling, skiing, hiking, bowling, and playing tennis.
