The details, handled with care.

When I started EllBee Services, I wanted to support the people who spend their days supporting others. Mental health professionals carry a lot, and the paperwork, billing, and credentialing that come with running a practice can quietly add to that weight. I’ve built a business myself, so I know firsthand how valuable steady, reliable help can be. I’m here to take care of the details so you can be fully present with your clients.

Choosing EllBee Services means partnering with a dedicated team that truly cares about your success and the well-being of your practice.

Why I do this work.

I’m Lesly. Before moving to the United States from the Philippines in 2013, I worked as an executive assistant. Here, I took a role as a business services representative for a behavioral health group, where I saw firsthand how complex mental health administration can be. I went on to earn a certificate in medical billing and coding, and I’m now completing my associate degree in health information management.

When my mother fell ill in the Philippines, her medical bills had to be paid out of pocket. EllBee Services started as part-time work to help support her through her illness. My first client was a local psychiatrist, and referrals from there led to more practices I could support. After she passed, I built it into a full-time business in her honor.

Today, I help mental health practices with billing, eligibility, credentialing, and the everyday details that keep things running smoothly.

  • "I trust her completely and rely on her 110%"

    “I feel like Lesly and I built my practice together from the start, as I have been working with her from day 1. She credentialed me with insurance companies, set up my EHR, and handled every aspect of billing. I trust her completely and rely on her 110%. If it weren't for Lesly, I would be lost and wouldn't be getting paid for my work as a therapist. She's always quick to respond and find a resolution to any problem. If you need a billing provider, I recommend Lesly without hesitation and with full confidence. She makes it all possible for me and I am grateful for her service. “

  • "Reasonable rates and peace of mind"

    "Lesly has been such a help to me in my practice. Lesly took the lead on my credentialing process and is now my go-to person for any billing challenges I face. She is very knowledgeable and responsive and resolves any issues I have had with billing very quickly and thoroughly. With her very reasonable rates, I have peace of mind that lets me focus on the clinical pieces of my work. Lesly has my highest recommendation!"

    -  Jen Malcolm-Brown, LICSW

  • "Predictable cash flow and better systems"

    “Lesly and her team were nothing short of amazing for my practice. When my former billing company did not follow through on claims or credentialing services, Lesly agreed to work with me and got everything straightened out. We now have a predictable cash flow with much better systems in place. She also fought with the insurance companies for reimbursement and was able to recoup almost $20,000 which the other billers had done incorrectly. I couldn't be more thankful for her work and dedication.”

  • "Pleasant, professional, and completely reliable"

    “I hired Ms. Guerin in 2016 to work in my private practice after noticing her competence and initiative in a group practice where we worked. I ran my office on a complex practice management software that she quickly mastered. In addition to managing the routine and special tasks I requested, she has proposed and carried out other organizing and documentation ideas for my office. She handles insurance and patient payments, claims tracking, patient billing, banking, scanning, and filing for me. She is pleasant to work with, professional, and completely reliable. I highly recommend her!"
