Meet the Team 

Meet your Coach, Dr. Tim Zittle

Associate. Partner. Solo Practitioner. Leader. Seven years into my chiropractic career, I looked around and realized that I was building everyone else’s dream but my own. I had been an integral part of creating and growing some of the most successful offices in the country but in doing so had lost sight of what matters most to me- the ability to empower every person I meet towards becoming the best version of themselves as I do the same. 
Professionally and on paper, things had never seemed more successful. I had overcome challenges at every level and had always done so in a way that led to more financial growth and bigger offices. I had achieved everything I had ever wanted from working under a doc as an associate, to building an office alongside of friends, selling that practice to start one of my own and bringing on a team including docs for me to lead. But something was still missing. Personally, I was broken across the board mentally, physically, and financially. I had given away all the abundance I was creating as fast as I received it along with my joy and fire for the life I had once envisioned. I had created a job for myself. A machine that for all its success was still dependent on me. I knew that if I was ever going to achieve my full potential, much less help others do the same, this would need to change. I connected with Dr. Elise Rigney and I dove headfirst into the Chirointensive community, taking the course for myself. 
Fast forward to now, I have a practice I’m in love with and for the first time in almost a decade I’m creating a life that is tailored towards my needs, experiencing freedom across the board. I have hours that allow me to serve people while still pursuing my passions. I speak and teach around the country and coach leaders and their teams on how to work better together. I’m building a team that’s dedicated to my success in the same way I’m committed to theirs and we have a thriving culture of growth and fun that is here to stay. 
I have been so fortunate to be coached and trained by some of the most successful chiropractors and businesspeople the world has ever seen. I have been a coach and consultant both inside and outside of chiropractic and to be able to bring all of that borrowed knowledge to create a space where you can become the best version of you is what keeps my fire burning and my head popping off the pillow ever morning with excitement. 
If we want to go fast, we’ll go alone. If we want to go far, we’ll go together. When you win, we all win. That is the gift of Chirointensive.

Meet Your Coach, Dr. Lauren Cost 

Setting goals and crushing them is something I really enjoy doing. Can you say major Enneagram 3? So, opening an office, and being successful out of the gate, is something I’m very thankful for but also worked really, really hard for. About 2 years into practice though, I was burnt out. I was overworked, overwhelmed, and was not sure where to go next. I felt that even though I was growing my patient base, I was not working "on" my business and I was scared that as we grew, I would have less and less time with my family. I know many other business owners have felt or do feel this way. After “meeting" Dr. Elise through social media, I found that we are very similar to our personalities, goals, and interests. When she created ChiroIntensive I’m sure I was one of the first people to sign up! This program was right up my alley because I love master-minding and bouncing ideas off of other business owners and I love learning new things. Her ability to run a HIGHLY successful business, and team, but have so much personal time and family time, really intrigued me. With all the knowledge that I learned through ChiroIntensive, I ran with it in our office and became even more successful, grew our team, and we became much more organized. 

I’m so excited to be one of the coaches for ChiroIntensive and help other business owners grow their office and love what they do. Dr. Elise and I recently talked about how you don’t even know what is possible if you’ve never seen it done before. This rang so true to me! After seeing the amazing business she grew, I knew that it was possible for me. I value the ideas, content, and personal growth that this program brings and challenges you to become.  I'm ready to share my story of how I got to where I am and helping other business owners reach their full potential.  I love my office, I love seeing patients but being able to be the CEO, I love my amazing team, and I love my family time. I want every business owner to LOVE every aspect of their office as well, so I am very excited to help you on your journey!

Meet Your Coach, Dr. Lara Summer 

As a 8th trimester student figuring her way out in this chiropractic world, I reached out to Dr. Elise looking for an opportunity to learn.  After a phone call that I didn’t realize was an interview, I booked a trip to visit Colorado for the first time ever.  After a morning of shadowing followed by a coffee date, which another interview I didn’t realize was happening, the my future as an associate at Impact Chiropractic was starting to take shape.  I transitioned from student intern, to newbie associate, to senior associate in less than 3 years.  As the lead associate I was leading a team of doctors, in charge of CA trainings, and being the go-to-gal for in office questions and weekly meetings.  Things were beautiful, until the realization hit that I could be doing all of this and earning even more out on my own. After 6 years of associating, it was time to open our sister location as partner.  My first year had massive growth and expansion and I hired my first associate before our 1 year anniversary hit.  Setting and surpassing goals was all about having an intentional mindset first.  Procedures and systems were already in place, so hitting goals was almost easy. Everything you will learn in ChiroIntensive is practical, works, and will set you above any other office in your area.  Business growth isn’t something that may happen to you after this program, it absolutely WILL happen.

Meet Your Coach, Dr. Abby Sirovica 

I have always been a dreamer, questioning why certain things have to be limited in any way.  As a chiropractor I love being able to serve patients but what I didn’t realize that I would love building and growing a business just as much.  When I experienced practice out of school, I worked in an office where we saw patients a full week, utilized extensive care plans they would purchase and spent weekends away from our families to market. I knew there had to be a way that felt in alignment with how I wanted to live and show up for people.  Fast forward 7 years later Grassroots Chiropractic has grown into Grassroots Collective.  We currently have two locations, three doctors and are getting ready to add on two more. We are only getting started. The culture we have is everything. Our people are everything.  We get to truly show up each day fully supported as humans, women and doctors.  The practice is 100% cash, our patients are members, most of them have their full families in within the first month and are utilizing chiropractic as a no-brainer for their family for lifetime wellness.  I own three residential rentals, adding another airbnb within the next month, soon to be three commercial buildings and closing on acquiring a gluten-free, dairy-free wellness cafe within the next 30 days. 


I believe the only thing that limits us is between our ears. I know there are so many ways we can build out joyful lives, supported teams and endless abundance. The best part we can stand shoulder to shoulder along the way with people doing it. Chirointensive was a level up for me and exactly that.  I could go on about all of the ways your systems will get better, your team will grow, your perception of what is possible will expand, how one conversation alone at the live event saved me $10,000 on my taxes but truly what will change is you. You will become a different version of you. If you are scared, good.  If you are uncertain, jump.  The universe has a great way of landing you in a bed of feathers; and if you need someone to remind you, you’ve got this, it is nice to meet you. Let's grow together.
