Our mature and compassionate team of caregivers and healthcare providers truly makes Unlimited Care Cottages a special place. Each person chosen to help us care for your loved one becomes a part of our close-knit family.

Candace Estes

Candace Estes

Assisted Living Director


Candace has been in long-term care since 2013 and received her Assisted Living Administrator Certification in 2014. Before starting in long-term care, she worked with underprivileged youth from all over the state of Texas. Her happiness is in helping and serving others and is evident in her chosen careers. She is compassionate and loves to be the person that families can lean on when it comes to helping them make some of the toughest decisions for their loved ones.

Candace meets people in all different situations with a multitude of family dynamics and feels led to help them each step of the way. Her goal as the Director of Unlimited Care is to bring families, care partners, and anyone else involved in a residents’ care together. She forms a true team for each resident in order to make the best decisions necessary for their comfort and care.

Candace is able to leave each day with a feeling of accomplishment in making a difference in someone’s life. She is humbled to be able to do this on a daily basis because it is so therapeutic for her. She pours her heart into each resident and family, so there are naturally days that she must leave with a heavy heart. Her response to these days is to prepare for the next and be able to provide the loving care and help that a new family is searching for.

In her role as the director, she introduces families and the community to our care homes. She is the first person families will typically meet and she guides them through the whole process, even after they move into one of our communities. Her passion and heart are evident when you meet her and become more clear as you become one of her families. Candace’s devotion to Unlimited Care and our residents and families is obvious. With Candace’s support, she makes a very tough experience one where you never feel as though you are going through it alone.

Marlene Wanjala

Marlene Wanjala

Director of Quality and Training


Woodlands, TX (June 27, 2017) – Marlene N. Wanjala has recently been promoted to Director of Quality and Training at Assisted Living by Unlimited Care Cottages. She previously held the position of Care Partner for the last three years and joined the company seven years ago in 2011.
Wanjala received a bachelor’s degree in management from Park University in Austin. She has earned professional certifications in Gerontology and End of Life Care from Houston Community College.
She is now responsible for providing consistent training among all care partners within the caregiving business.
Assisted Living by Unlimited Care Cottages was founded in 1998 by co-owners Buck and Terri Buckholtz. Today, their caregiving business has seven assisted living and memory care personal cottages in The Woodlands and Spring areas.
Each cottage offers a unique, cozy, home-like alternative to larger, more traditional assisted living communities or nursing homes for families in need of care for an aging parent or relative. Staffed 24/7 by full-time, live-in care partners, the cottages boast a high staff-to-resident ratio for the caregiving industry. Private and companion rooms are offered for residents whose needs range from minimum to maximum care with assistance with activities of daily living, such as bathing, dressing, transferring, and medication reminders.
Transitional care for elderly patients who need extra help after a lengthy stay in the hospital or a rehabilitation center, as well as temporary respite care is also offered as space is available.
Cottage residents enjoy home-cooked meals in the kitchen and sitting out on the front and back porch. They can also participate in activities, such as music therapy, and they have access to volunteer services, house call physician services, hospice, and home health services. Other services, such as hair and nail care, are also provided for the residents.
“We are very proud to announce the promotion of Marlene,” said Buck Buckholtz. “She has been a loyal member of our care team and has worked hard to improve her professional education and skills throughout her tenure with us. In her new and expanded role, she is continuing to make a difference in the lives of residents we serve each day. Our philosophy is to take care of the people who take care of our people.”

Sonia Botello

Sonia Botello

Resident Care Coordinator


Hello, my name is Sonia Botello and I am originally from Mexico. I came to the US in 1976 at age 14 and graduated from John H Reagan HS. I became a US citizen in 1996. I got married in 1983 and have 4 beautiful kids and proud to be a grandma of 2 lovely grandchildren. Working with kids and seniors is my passion and I am so fortunate to be able to combine the two. I became employed with Unlimited Care through a former resident, Mr. Dale. I was his private caregiver for 5 years and when he moved into one of the cottages at Unlimited Care, that’s how I met Buck & Terri. I feel like that is when I became part of what I call my second family. I have been with Unlimited Care Cottages for 4 years and my title has progressed to Resident Care Coordinator which involves so many different details that I love overseeing and being involved with. This is truly my life’s calling.

Shannon Hill

Registered Nurse


I started my nursing career later in life. I was blessed to be able to be a stay at home Mom while my children were young. After graduating from nursing school in Missouri, I worked in a hospital on the med-surg floor for 5 years. We then were transferred to Texas with my husband’s job. Thankfully I was able to take a little time off to get settled in our new surroundings. Most recently, before working for Unlimited Care, I worked for a local hospice company

I feel very blessed to be working with such wonderful residents, gifted caregivers, and also Terri, Buck, Candace, and the entire Unlimited Care family.

Mercy Kimuhu

Mercy Kimuhu



Mercy Kimuhu serves the patients at Unlimited Care Cottages as a Licensed Vocational Nurse. Her responsibilities include managing her patients’ conditions, administering prescribed medications, and helping caregivers learn how to best care for them.
Originally from Kenya, Mercy now lives in Spring, TX and has been with Unlimited Care Cottages since 2011. She brought with her previous experience working as a caregiver and a Certified Nursing Aid for The Woodlands Healthcare and several home health care companies. She is currently studying to become a Registered Nurse.
Mercy enjoys being able to care for people and meeting all their needs. She has the heart to provide care that is attentive and complete. It’s a joy for her knowing her patients are happy with the care they receive.
Mercy chooses to provide personal care services at Unlimited Care Cottages because of the small setting. It is satisfying for her to know that she can reach every person in the assisted living community, something that would not be possible in a larger setting.
“Unlimited Care is just like a small community. People here work together and help each other as a team. There’s nothing that can beat that.”
When Mercy is not working, she enjoys traveling back to Kenya to visit her family.

Amber returned to the states, got married, and took the next 10 years to focus on being a mommy to her two sons.

After staying home for year 10, it was time to launch back out into the work force. Amber accepted a position as Administrative Assistant with Carter Home Healthcare. After sitting behind a desk for several years learning the industry she was promoted to Professional Sales Coordinator. She worked in the field for a year gaining experience. Amber then accepted the position of Area Manager with Encompass Home Healthcare.

Tiffany Cutbirth



Tiffany began her career as an RN, graduating from Seton Hall University in 1995. As an RN, she practiced in multiple settings, including internal medicine, school nursing, and home health. Her experiences within the geriatric community as a home health nurse inspired her to complete her Master’s in Nursing as a Nurse Practitioner, where she graduated from The University of Texas Health Science Center in Houston in 2011. She began her Nurse Practitioner career in an office setting for a Family Practice but quickly turned her focus towards providing healthcare services for the geriatric homebound population, a vastly underserved population in great need of alternative care solutions. In 2015, Tiffany decided to create her own practice which enabled her to provide comprehensive care coordination for this critical patient population and their families.
Today, Tiffany owns and operates The Lady with the Lamp where she and her team of Nurse Practitioners and staff continue to provide care for their homebound patients. Her business is located in Kingwood, TX and serves patients in Kingwood, Humble, Atascocita, Spring, The Woodlands, Conroe, and Porter areas with plans for additional expansion in 2017.
