Atakan is dedicated with a fantastic work ethic. Honest, dependable and friendly. Highly recommend

The business does a great job and he is on top of things

It was a pleasure working with the owner of Bio-One Fremont. A huge burden was lifted after he and Atakan sanitized and deodorized the garage and shed after rodents left a nasty mess. They did a great job of filling their trucks with items that needed to be hauled away. He is very responsive to calls, texts and emails. Great job guys and thank you so much!

I’ve known him for many years and can vouch that he is a man of integrity, a natural problem-solver committed to doing the right thing. His positive can-do attitude combined with his efficient professionalism will ensure the successful completion of your project.

I recently hired a professional clean up service in Fremont, CA, and I am thrilled to share that they are trustworthy professionals. From the moment I contacted them, their professionalism was evident. They were prompt, reliable, and displayed a high level of expertise. I felt confident entrusting them with the task at hand, and they exceeded my expectations. I highly recommend their services for anyone seeking reliable and trustworthy professionals for their clean up needs.

Bio-One proved to be an incredible source of support and assistance for my family during a time of unexpected tragedy after the passing of my beloved grandmother. Their team exhibited immense compassion and professionalism as they handled the difficult task of cleaning the affected area with sensitivity and care. Their expertise and attention to detail brought a sense of comfort during an emotionally challenging period. Bio-One's unwavering dedication and understanding helped alleviate some of the burdens we faced, and we are forever grateful for their invaluable assistance in our time of need.

"I am so grateful for Bio-One. I called and spoke with the owner, and he gave me a next day appointment. The price was competitive. I had an infestation of mice, and they were located primarily in the pantry. He reassured me that this was a job his business could handle and walk me through the process so I would know what to expect. On the day of the appointment he sent me a reminder Text and another text to let me know when he was in route. He and his nephew, Mr. Atakan Efe, arrived 10 minutes early to the job. I showed them the pantry and they got to work. They went above and beyond not only cleaning/guttering/disinfecting the pantry, but also cleaned underneath the stove, refrigerator, and the ENTIRE floor. They also plugged the holes where the mice were coming out of. They gave me advice on what to do next. I am above and beyond grateful for them. I feel like I can use my kitchen again. I really appreciate this business for their professionalism, honesty, and hard work."

I've known him for more than a decade and worked with him on a variety of non-profit activities for the past five years. He has drive and a commitment to excellence in everything that he does. What impresses me most is his ability to work across generations and personality types to gain consensus on challenging issues, and then drive to a positive resolution. He always seems to have the end result front and center in his thinking. This helps him see past potential roadblocks and drive to the desired outcome. He's organized, methodical in his approach, and detail oriented. Best of all, he is simply a great person. Someone you genuinely like to be around because he makes you feel important, and puts your welfare equal to his own. In client service, I can think of no better characteristic.
